    Princeton University/Institute for Advanced Study Early Universe/Cosmology Lunch Discussion
    “Extreme Emission Line Galaxies (EELs) as a Platinum Redshift Sample for Galaxy Clustering Measurements with LSST”

    Location: Institute for Advanced Study, West Building, West Seminar Room
    Time: 12:30 PM
    Speaker(s): Adam Broussard, Rutgers, The State University of New Jersey

    Description: The Large Synoptic Survey Telescope (LSST) is projected to observe approximately 25 billion galaxies, which will be incredibly useful for measurements of galaxy clustering and large scale structure in the Universe.  One of the primary limiting factors in a galaxy clustering analysis, however, is the determination of photometric redshifts for a large sample of these galaxies.  While the longstanding expectation is that red sequence galaxies with a strong Balmer/4000 Angstrom break have the spectral shape that provides the most precise redshift fits, we consider the alternative of galaxies that exhibit extreme emission lines (EELs).  We find that EELs are numerous enough to beat the shot noise and are therefore a promising sample for LSS measurements.

  • Tuesday, October 22, 2019
    Institute for Advanced Study/Princeton University Joint Astrophysics Colloquium
    “Red Supergiants: New Perspectives on Dying Stars”

    Location: Bloomberg Hall Lecture Hall
    Time: 11:00 AM
    Speaker(s): Emily Levesque, University of Washington
    Note: Coffee and refreshments are available from 10:30 am in the Bloomberg Hall Commons Room. Lunch will be provided for all and available in the back of the Dilworth Room. Please enter the Dilworth Room using the last door in the hallway.

    Description: Red supergiants (RSGs) are the helium-fusing descendants of moderately massive (10-25Mo) stars. As the coldest and largest (in physical size) members of the massive star population, these evolved stars serve as ideal "magnifying glasses" for scrutinizing our current understanding of massive stars and their role as supernova progenitors. RSGs are the observationally-confirmed progenitors of Type II-P, an intermediate evolutionary phase in the lifetimes of some stripped-envelope SN progenitors, and a crucial step in the formation and population statistics of massive interacting binaries (including those that will ultimately produce compact object binaries and gravitational waves). This talk will provide an overview of our field's current knowledge of RSGs, identify some of the most pressing open questions about these stars and their role as supernova progenitors, and consider the importance of RSGs in the coming decade as the next generation of observatories comes online.

    Deep Learning for Physics
    “Talk #1: Machine Learning Techniques for Many-Body Quantum Systems; Talk #2: Autoregressive Simulation of Many-body Quantum Systems”

    Location: Jadwin Hall, PCTS Seminar Room 407
    Time: 11:45 AM
    Speaker(s): Giuseppe Carleo, CCQ, Flatiron Institute, Or Sharir, Hebrew University of Jerusalem
    Note: Each talk will be preceded with lunch at 11:45 am. The talks will be held from 12:25-1:30 pm. Please check the specific date for room location.

    Description: Registration for each event is free, but required.  Please click on the registration link below for each date, as it becomes available.

    Talk #1: Machine Learning Techniques for Many-Body Quantum SystemsIn this introductory seminar I will cover the main machine learning techniques so-far adopted to study interacting quantum systems. I will first introduce the concept of neural-network quantum states [1], a representation of the many-body wave-function based on artificial neural networks. Theoretical aspects of these representations, including the problem of including symmetries, and their entanglement capacity will be discussed. Then, I will show how neural-network quantum states can be used in a variety of applications. Examples will be given for data-driven, experimental analysis in the context of quantum state tomography [2]. I will also show how these states can be used in variational applications to theoretically study the physical properties of interacting many-body matter, highlighting recent applications to frustrated magnetism [3] and fermionic systems [4].[1] Carleo, and Troyer - Science 355, 602 (2017); [2] Torlai, et al. - Nature Physics 14, 447 (2018); [3] Choo, et al. - arXiv:1903.06713 (2019); [4] Pfau, et al. - arXiv:1909.02487 (2019).

    Talk #2: Autoregressive Simulation of Many-body Quantum SystemsUnderstanding phenomena in systems of many interacting quantum particles, known as quantum many-body systems, is one of the most sought-after objectives in contemporary physics research. The challenge of simulating such systems lies in the extensive resources required for exactly modeling quantum wave-functions, which grows exponentially with the number of particles. Recently, neural networks were demonstrated to be a promising approximation method of quantum wave functions. However, thus far, this approach was mostly focused on more traditional architectures such as Restricted Boltzmann Machines and small fully-connected networks. In this talk, we propose a method for scaling this approach to support large modern architecture. Though significantly more expressive, such architectures do not lend themselves to the conventional methods for employing neural networks for simulating quantum systems. A key part of the simulation is to sample according to the underlying distribution of particle configurations. Current methods rely on Markov-Chain Monte-Carlo sampling, which is too expensive for use with modern architectures, effectively limiting their usable size and capacity. Inspired by recent generative models, we propose a specialized deep convolutional architecture that supports efficient and exact sampling, completely circumventing the need for Markov Chain sampling. We demonstrate our approach can obtain accurate results on larger system sizes than those currently accessible to other neural-network representation of quantum states.

    Institute for Advanced Study / Princeton University Bahcall Lunch

    Location: Dilworth Room
    Time: 12:15 PM

    Description:  

  • Tuesday, October 22, 2019
    Pheno & Vino Seminar
    “Functional Methods and Universal One-Loop Matching in HQET and Beyond”

    Location: Jadwin Hall, Room 303
    Time: 4:00 PM
    Speaker(s): Marat Freytsis, Rutgers University

    Description: Functional methods, in particular efficient reorganization of the one-loop effective action, have recently made a reappearance in simplifying the problem of computing matching and running effects in Lorentz-invariant effective field theories (EFTs) such as the Standard Model Effective Field Theory. This has lead to the appearance of universal one-loop effective actions, where such effects are now known in closed form for arbitrary field-content. These insights have not yet been brought to bear on modern kinematic EFTs such as heavy quark (HQET) and soft-collinear effective theory despite their greater focus on precision and the inclusion of higher-order effects. I will present some first steps in developing functional one-step matching formulae for EFTs where Lorentz symmetry is broken (or at least obscured) using HQET as my focus but also commenting on more complicated multi-mode EFTs as well.

  • Wednesday, October 23, 2019
    Princeton University Star Formation/ISM Rendezvous (SFIR)
    “Cosmic Ray Transport and the Galaxy Gas Cycle”

    Location: Peyton Hall, Dome Room, Room 201
    Time: 11:00 AM
    Speaker(s): Chad Bustard, University of Wisconsin-Madison

    Description: Despite representing only a billionth of the gas population, cosmic rays have enough energy to significantly shape the structure of the ISM, the supernova-driven outflows that emanate from it, and the surrounding circumgalactic medium (CGM), which contains a large fraction of the baryons in the galactic ecosystem. They exert this influence, however, through micro-scale interactions with plasma fluctuations on scales of order 1 AU. Fully realizing the macroscopic, observable effects of cosmic rays, therefore, requires a truly cross-disciplinary effort between astronomy and plasma physics. I will present two recent projects in which I leverage novel numerical techniques and plasma physics-based cosmic ray treatments to simulate cosmic rays in galaxies. This talk will go from small-to-large scales, building in complexity from intuition-building studies of the Parker instability (Heintz, Bustard, and Zweibel 2019) to the role of cosmic rays in the complicated environment of the Magellanic System (Bustard+ 2019, in prep). We find, in each study, that cosmic rays shape their surroundings to promote a flux of gas, magnetic fields, and cosmic rays from disks, develop a cosmic ray dominated halo, and significantly affect the gas phase structure in halos and the CGM. This cosmic ray impact on the galaxy gas cycle promises to narrow gaps between observed and simulated outflows, with the Large Magellanic Cloud being an intriguing, nearby example. Future work to more thoroughly characterize the cosmic ray flux out of the multiphase, turbulent ISM is necessary.

  • Wednesday, October 23, 2019
    University of Pennsylvania Physics & Astronomy Colloquium
    “Finding Other Earths – New Frontiers in Exoplanet Science with Next-Generation Doppler Spectrometers”

    Location: David Rittenhouse Laboratory (209 South 33rd Street), Room A8
    Time: 4:00 PM
    Speaker(s): Cullen Blake, University of Pennsylvania

    Description: The Doppler technique is a key tool for discovering and characterizing planets orbiting other stars. By measuring periodic shifts in stellar spectral lines as a star and its planets orbit around the system center of mass, exoplanets can be discovered. In some cases, the masses of these planets can even be directly measured. These measurements allow us to probe the internal compositions of these newly discovered worlds, constrain models of planet formation, and put future direct measurements of planets atmospheric properties into context.  Over the past three decades, advances in technology have made it possible to achieve 1 m/s velocity precision in the measurements of Sun-like stars. However, if we hope to detect analogs of terrestrial planets like those in our solar system orbiting Sun-like stars, velocity precision will need to improve substantially. Earth induces just a 10 cm/s wobble in the Sun. Understanding a host of astrophysical and instrumental noise sources becomes important for measuring stellar velocities with a precision below 1 m/s. I will describe NEID and MINERVA-Red, two new instruments that my team here at Penn helped build, which are designed to push the limits of ground-based Doppler measurement precision and open up new scientific opportunities in exoplanet detection and characterization.

    Institute for Advanced Study Informal Astrophysics Seminar
    “Characterizing Star-Planet Systems with Precision Spectroscopy”

    Location: Bloomberg Hall, Astrophysics Library
    Time: 11:00 AM
    Speaker(s): Megan Bedell, Center for Computational Astrophysics, Flatiron Institute

    Description: More than two decades after the discovery of the first exoplanet with radial velocity (RV) measurements, vast quantities of data exist from dedicated planet-hunting spectrographs. These spectra play an important role not only in the discovery and characterization of planets but also as a rich source of information about bright stars in the solar neighborhood. I will summarize efforts to gain insight into the planet formation process via extremely precise (0.01 dex) differential abundance measurements of nearby stars with and without planets using RV spectra. I will also discuss recent work on extending the power of next-generation RV spectrographs to detect Earth analogs around these stars.

    Princeton University Thunch Talk - Tittle Added
    “Galactic Archeology of the Brightest Cluster Galaxy M87”

    Location: Peyton Hall, Room 033 (basement)
    Time: 12:15 PM
    Speaker(s): Alexa Villaume, University of California, Santa Cruz

    Description: The galactocentric radial metallicity gradients of GC systems can be used to probe the assembly histories of galaxies but doing so is complicated by: 1.) a GC system is an aggregate population of several (or many) different subpopulations of different origins, and 2.) computing the gradients with respect to projected galactocentric distances can artificially flatten the gradient. I describe a hierarchical statistical framework measure the radial metallically gradients of the GC subpopulations and its application the brightest cluster galaxy M87 using spectroscopically-derived metallicities for a large sample of GCs. Contrary to much previous work I find that the metal-rich and metal-poor subpopulations have different gradients, indicating they were affected by separate events. Moreover, I find the gradients change between the inner and outer halo, indicating that M87 has at least two merger events in its assembly history. I describe the results of doing weak chemical tagging'' on  physically-motivated spectral stacks of the GC subpopulations and compare these results to the stellar parameters derived spatially-resolved spectroscopy for the galaxy light of M87. I will discuss these results in context of the formation and assembly history of M87 and assess how well predictions from cosmological galaxy formation simulations match our results.

    Rutgers University Astrophysics Seminar
    “Interpreting the Kitchen Sink: a Path Towards Better Understanding Galaxy Evolution”

    Location: Serin Hall, Room W330
    Time: 1:30 PM
    Speaker(s): John Forbes, Center for Computational Astrophysics, Flatiron Institute
    Note: Refreshments to follow in room W332.

    Description: Galaxy formation is a field currently overwhelmed by data, from large surveys to cosmological simulations. As the simulations continue to improve their matches to the observations, some have been left wondering whether the basic picture of galaxy evolution is settled. I will argue that this is far from the case, and that a sophisticated new generation of semi-analytic models and statistical techniques are needed to simultaneously address the strong degeneracies that persist in the problem of galaxy evolution and to coherently comprehend the vast quantities of extant and forthcoming data.

    Princeton University Astroplasmas Seminar
    “Two-temperature, Radiative GRMHD Simulations of Sgr A* and M87”

    Location: Peyton Hall, Dome Room, Room 201
    Time: 12:30 PM
    Speaker(s): Andrew Chael, Princeton University

    Description: The Event Horizon Telescope (EHT) is a global VLBI array with a 25 microarcsecond resolution, fine enough to image the black hole shadows in Sgr A* and M87. The ionized accretion flows around both the black holes in Sgr A* and M87 are hot (T>10^11 K) and diffuse, and thus expected to have an electron temperature that is distinct from the ion temperature. Standard general relativistic magnetohydrodynamic (GRMHD) simulations of these systems only solve for a single fluid temperature dominated by the ions, making it difficult to directly connect simulations to images from the EHT and multiwavelength observations. We have implemented a method for evolving a two-temperature electron-ion fluid in radiative GRMHD simulations implemented in the code KORAL. I will discuss two sets of 3D, two-temperature GRMHD simulations I performed both for Sgr A* and M87, their implications for EHT and multiwavelength observations, and the prospects for connecting images of Sgr A* and M87 to the underlying plasma processes that heat and accelerate electrons in accretion flows.

    Hamilton Colloquium Series
    “The Event Horizon Telescope: Imaging a Black Hole”

    Location: Jadwin Hall, Room A10
    Time: 4:00 PM
    Speaker(s): Shep Doeleman, Center for Astrophysics | Harvard & Smithsonian

    Description: The Event Horizon Telescope (EHT) is a Very Long Baseline Interferometry (VLBI) array operating at the shortest possible wavelengths, which can resolve the event horizons of the nearest supermassive black holes. Observing at mm radio wavelengths enables detection of photons that originate from deep within the gravitational potential well of the black hole, and travel unimpeded to telescopes on the Earth. The primary goal of the EHT is to resolve and image the predicted ring of emission formed by the photon orbit of a black hole and to eventually track dynamics of matter as it orbits close to the event horizon. A sustained program of improvements to VLBI instrumentation and the addition of new sites through an international collaborative effort led to Global observations in April 2017: the first campaign with the potential for horizon imaging. After 1.5 years of data reduction and analysis we report success: we have imaged a black hole. The resulting image is an irregular but clear bright ring, whose size and shape agree closely with the expected lensed photon orbit of a 6.5 billion solar mass black hole. This talk will cover the project and first results as well as future directions for a next-generation instrument that is aimed at real-time black hole video.

    “Einstein’s Dream — From the Big Bang to Black Holes”

    Location: McDonnell Hall, Room A02
    Time: 8:00 PM
    Speaker(s): Robbert Dijkgraaf, Director, Institute for Advanced Study
    Note: A free lecture open to the public.

    Description: We are living in the golden era of gravitational research, realizing Einsteins vision that by studying the geometry of space and time we can determine the origin, composition, and fate of the Universe. Cutting-edge technology has opened up many new windows in science, from the detection of the remnants of the Big Bang and gravitational waves to the image of a supermassive black hole. Yet, deep questions remain about the dark matter, dark energy, and the nature of quantum space-time.

    “Atomic Qubits in Silicon”

    Location: Jadwin Hall, Room A10
    Time: 4:00 PM
    Speaker(s): Michelle Simmons, University of New South Wales, Australia

    Description: Phosphorus atoms qubits in silicon have demonstrated extremely long (up to 35 s) coherence times with >99.9% fidelity in the highly manufacturable material silicon. Their small size, combined with the magnetically quiet environment of isotopically pure silicon, make them analogous to ion trap qubits but in a scalable solid-state system. One of the long-term challenges for semiconductor qubits is to understand, and control, the local electromagnetic environment of the qubit down to sub 10nm length scales. Scanning probe techniques, combined with molecular beam epitaxy allow us to engineer fully crystalline devices at the atomic scale and directly probe the qubit wave function with exquisite precision. We will discuss the progress and vision for this approach.

    Hamilton Colloquium Series
    “The Revolution of Silicon Photonics”

    Location: Jadwin Hall, Room A10
    Time: 4:00 PM
    Speaker(s): Michal Lipson, Columbia University

    Description: We are now experiencing a revolution in optical technologies, where one can print and control massive optical circuits, on a microelectronic chip. This revolution is enabling a whole range of applications that are in need for scalable optical technologies and it is opening the door to areas that only a decade ago were unimaginable.

    In the past decade, the photonic community witnessed a complete transformation of optics. We went from being able to miniaturize a handful of devices to being able to define and control the flow of light using thousands of monolithically integrated optical components all on a silicon chip. The main drive for silicon photonics is the ability to transmit and manipulate ultra high bandwidth with low power dissipation. Today there are hundreds of products being developed and commercialized towards this goal.

    The field of silicon photonics is rapidly evolving and is now enabling completely new applications, ranging from Lidar to biomedical devices. This is partly due to the development of novel chip-scale technologies, novel devices and novel materials compatible with silicon photonics. Many of these technologies and devices can manipulate light across the whole VIS, IR and the Mid IR spectrum. I will discuss these emerging applications, as well as the advancement brought by these novel devices and materials.

    The key challenges of the field relate to the scalability of the systems in bandwidth, size and power. Some of these challenges are fundamental and require innovations that break traditional tradeoffs. Novel approaches for switching, modulating and amplifying light have emerged that can open the door to applications that rely on such scalable systems. I will describe the challenges of the field and some of the recent innovations that can potentially address these challenges.
