    Institute for Advanced Study/Princeton University Joint Astrophysics Colloquium
    “Probing Behind the Man in the Moon: Results from NASA’s GRAIL Mission”

    Location: Bloomberg Hall Lecture Hall
    Time: 11:00 AM
    Speaker(s): Jay Melosh, Purdue University
    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: NASA’s GRAIL mission to the Moon was completed in 2012 when both spacecraft were intentionally “de-orbited” (i.e. crashed) into a nearside mountainside. This orbital mission measured tiny variations in the Moon’s gravitational field by continuously monitoring the distance between two co-orbiting spacecraft (dubbed Ebb and Flow) to a precision of less than 0.1 micron. The resulting enormous improvement in the gravity field reveals buried structures otherwise hidden from view, from the underpinnings of large impact scars and the nearside lava flows down to a detection of the Moon’s core and perhaps an inner core. We have finally achieved a clear understanding of the previously mysterious mascons that posed a navigational hazard to the Apollo spacecraft and can now document a complete catalog of all of the ancient and, in many cases, otherwise invisible scars of large impacts that have breached the Moon’s crust. The Moon’s gravity field turns out to be qualitatively different from that of the other terrestrial-type planets in our solar system, but is now yielding insights into the nature of the earliest crusts of planetary bodies.

    “How Stellar Feedback and Cosmic Rays Shape Galaxies and Their Halos”

    Location: Peyton Hall, Dome Room, Room 201
    Time: 11:00 AM
    Speaker(s): Tsang Keung, University of California, San Diego

    Description: Stellar feedback is an indispensable component in galaxy evolution, which regulates star formation, drive galactic winds, and shape the galaxy structures. With the Feedback in Realistic Environment (FIRE) simulations, I demonstrate the importance of stellar feedback with a few examples: 1. how stellar feedback modifies the underlying dark matter halo structures, 2. how stellar feedback produces diffuse dwarf galaxies, e.g. ultra diffuse galaxies. In the second part of my talk, I will focus on an important kind of stellar feedback cosmic ray (CR) feedback, which we have recently implemented in the code GIZMO and coupled to the FIRE stellar feedback model. I will demonstrate its strong effects on galaxies, e.g. star formation, galactic wind, and circum-galactic medium, but the effects highly depend on the CR propagation model. I will then show how to constrain those models by comparing our simulations with the observed gamma ray emission. Finally, I will discuss the ongoing research and future direction on CR feedback.

    “Ice Fishing for Neutrinos”

    Location: Main Building Auditorium, 3141 Chestnut Street, Philadelphia, PA 19104
    Time: 1:00 PM
    Speaker(s): Francis Halzen, University of Wisconsin - Madison
    Note: Online registration is requested at their website.

    Description: The IceCube project at the geographic South Pole melted eighty-six holes over 1.5 miles deep in the Antarctic icecap to construct an enormous astronomical observatory. The experiment recently discovered a flux of neutrinos reaching us from the cosmos, with energies more than a thousand times those of neutrinos produced at accelerator laboratories. These cosmic neutrinos are astronomical messengers coming from some of the most violent processes in the universe and from the biggest explosions since the Big Bang. Recently it was discovered that some high-energy neutrinosand cosmic raysoriginate from sources powered by rotating supermassive black holes.

    “The Planck Legacy: Inflation and the Origin of Structure in the Universe”

    Location: David Rittenhouse Laboratory (209 South 33rd Street), Room A8
    Time: 4:00 PM
    Speaker(s): George P. Efstathiou, University of Cambridge and Kavli Institute for Cosmology

    Description: I will review the latest results on cosmic microwave background (CMB) anisotropies measured by the Planck satellite. These measurements agree extremely well with a spatially flat, cosmological constant dominated cosmology with nearly scale invariant Gaussian fluctuations, as predicted by inflationary models of the early Universe. However, there are some discrepancies with other astrophysical measurements, most notably with direct measurements of the Hubble constant. The Planck measurements also show the emergence of a hierarchy in the parameters defining inflationary models. Should we worry about these results? I will argue that these peculiarities may be pointers to new physics.

    Institute for Advanced Study Informal Astrophysics Seminar
    “Rare Views of Galaxy Cluster Laboratories”

    Location: Bloomberg Hall, Astrophysics Library
    Time: 11:00 AM
    Speaker(s): Brenda Frye, The University of Arizona and Steward Observatory

    Description: Galaxy clusters as astronomical tools generally offer two advantages: to boost the brightnesses of objects in the background, and to study the dark matter in the lens.  We can now introduce a third use: to unveil properties of the underlying dark matter by the detection of caustic crossing events which can yield magnification factors of 10,000 or more.  We review the approach to detect a new set of massive objects such as galaxy clusters by their rest-frame far-infrared colors (and not by the Sunyaev-Z'eldovich effect).  We move on to present Hubble Space Telescope WFC3-IR imaging in the fields of six classical giant arcs discovered using a combination of Planck and Herschel space facilities.  We construct lensing models from the many examples of image multiplicities, and compare our results with galaxy over-densities identified by more conventional methods.  We conclude with a discussion on the emerging field of caustic crossings, for which we address the question of which are the very best giant arcs for the detection of microlensing events in high magnification regions.

    Rutgers University Astrophysics Seminar
    “Detection of Cool Accretion Disk around the Galactic Centre Black Hole Sagittarius A*”

    Location: Serin Hall, Room 401
    Time: 1:30 PM
    Speaker(s): Elena Murchikova, Institute for Advanced Study
    Note: Refreshments to follow in room 332W.

    Description: A supermassive black hole Sagittarius A* (SgrA*) with the mass M_SgrA*= 4x10^6 M_sun, deduced from the orbits of nearby stars, resides at the centre of our galaxy. Building up such a massive black hole within the 10^10 year lifetime of our galaxy would require a mean accretion rate of ~ 4x10^{-4} M_sun/yr. However, X-ray observations constrain the rate of hot gas accretion at the Bondi radius (10^5 R_Sch = 0.04 pc) to \dot{M}_Bondi~3x10^{-6} M_sun/yr, and polarization measurements constrain it near the event horizon to \dot{M}_{horizon}~10^{-8} M_sun/yr. What happens to the gas in between, what its physical state, its source, and the exact accretion mechanism present a long standing puzzle, primarily due to the absence of model-independent probes at intermediate radii. Here we report a detection and imaging of the 10^4 K ionized gas disk within 2x10^4 R_Sch in a millimetre hydrogen recombination line H30alpha: n = 31 -> 30 at 231.9 GHz using the Atacama Large Millimeter/submillimeter Array (ALMA). The emission was detected with a double-peaked line profile spanning 2,200 km/s with the approaching and the receding components straddling SgrA*, each offset from it by 0.11 arcsec = 0.004 pc which indicating a rotating disk of a mass 10^{-4} - 10^{-5} M_sun at a mean hydrogen density 10^5-10^6 cm^{-3} depending upon whether or not we assume the presence of a uniform density disk or an ensemble of orbiting clouds. This detection provides spatial and kinematic information on the accretion disk on scales a factor of ~10 smaller than what was possible before.

    “Wonders of Viscous Electronics”

    Location: Jadwin Hall, Room A10
    Time: 4:00 PM
    Speaker(s): Gregory Falkovich, Weizmann Institute of Science

    Description: Quantum-critical strongly correlated systems feature universal collision-dominated collective transport. Viscous electronics is an emerging field dealing with systems in which strongly interacting electrons flow like a fluid. Such flows have some remarkable properties never seen before. I shall describe recent theoretical and experimental works devoted, in particular, to a striking macroscopic DC transport behavior: viscous friction can drive electric current against an applied field, resulting in a negative resistance, recently measured experimentally in graphene. I shall also describe conductance exceeding the fundamental quantum-ballistic limit, field-theoretical anomalies and other wonders of viscous electronics. Strongly interacting electron-hole plasma in high-mobility graphene affords a unique link between quantum-critical electron transport and the wealth of fluid mechanics phenomena.

    Princeton University Astroplasmas Seminar
    “Fragments from the Origins of the Solar System and our Interstellar Locale (FOSSIL): A Cometary, Asteroidal, and Interstellar Dust Mission Concept”

    Location: Peyton Hall, Dome Room, Room 201
    Time: 12:30 PM
    Speaker(s): Neal Turner, Jet Propulsion Laboratory / California Institute of Technology

    Description: Comets and asteroids preserve the least-altered materials remaining from the birth of the Solar System.  However, the few visited by spacecraft are diverse in composition, and touring enough of these small bodies for a representative sample would be costly and time-consuming.  A team of us is therefore developing a proposal for a mission to measure the makeup of large numbers of comets and asteroids via the dust they shed into the Zodiacal Cloud. The mission concept, Fragments from the Origins of the Solar System and our Interstellar Locale (FOSSIL), would carry four identical Dust Telescopes whose combined collecting area would yield measurements of the orbits and compositions of tens of thousands of the zodiacal particles, along with about a thousand of the interstellar particles that are constantly traversing the Solar System.  These measurements would enable FOSSIL to reach four science objectives: (1) determine whether Jupiter-Family Comets' fine-grained components preserve unprocessed presolar molecular cloud particles, or show signatures of processing in the Solar System; (2) determine whether the rocky composition of the contemporary local interstellar cloud's dust population is consistent with being the feedstock for the formation of the Solar System; (3) determine whether comets' and asteroids' organics are genetically related, or formed from distinct reservoirs; and (4) determine the numbers and orbits of micron-sized particles originating from each of the three categories -- comets, asteroids, and interstellar dust -- in the Solar debris disk at 1 AU. FOSSIL's panoramic view of primitive Solar System bodies' chemical diversity, and its comprehensive measurement of interstellar dust sizes and compositions, would contribute to answering three of the major questions posed in the most recent Planetary Science Decadal Survey: What were the initial stages, conditions, and processes of Solar System formation, and the nature of the interstellar matter that was incorporated?  What were the primordial sources of organic matter?  And how have myriad chemical and physical processes shaped the Solar System?  FOSSIL also would contribute to heliospheric science by measuring interstellar particles' deflection in the Solar wind, and to astrophysics through its measurements of the only debris disk where we can study individual particles and their parent bodies -- our own Zodiacal Cloud.  Furthermore, by measuring both the particles' orbits and their compositions, FOSSIL would link decades of ground-based meteor trajectory data, lacking compositions, to decades of laboratory studies of meteorites and micrometeorites, lacking orbits.  In particular, FOSSIL would tell us which families of bodies are the most likely sources of existing laboratory specimens. Each of FOSSIL's four Dust Telescopes consists of a Dust Trajectory Sensor (DTS) and an impact ionization reflectron-type time-of-flight mass spectrometer, the Composition Analyzer (CA).  The DTS and CA are derived from and would use similar technology to previous and current flight instruments, especially the Cosmic Dust Analyzer (CDA) onboard Cassini, the Lunar Dust Experiment (LDEX) onboard the Lunar Atmosphere and Dust Environment Explorer (LADEE), and the Surface Dust Analyzer (SUDA) instrument in development for Europa Clipper. In summary, FOSSIL would be a low-risk mission to survey the composition of the Solar System's primitive material at a cost far lower than sending probes to a representative sample of small bodies.  Building on in situ and returned sample measurements of cometary, asteroidal, and interstellar particles' compositions from the Giotto, Vega, Ulysses, Stardust, Rosetta, Cassini, and OSIRIS-REx missions, FOSSIL would enable breakthroughs in understanding our Solar System's largest visible structure, the Zodiacal Cloud, and reading its record of the origins of our planetary system.

    “The Milky Way's Stellar Streams and its Galactic Bar”

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

    Description: As clusters of stars orbit our own Milky Way, a gravitational tidal interaction unfolds and the clusters tear apart into distinct morphological and kinematic structures.  From our understanding of gravity, the distribution and motion of these stellar structures enable us to work backwards in time and thereby study our Milky Way's past and evolution. Stellar streams additionally provide promising prospects for detecting dark matter substructure through disturbances in the streams structure - for example in the form of distinct under densities in their stellar distributions. Palomar 5 (Pal 5) is an old globular cluster orbiting our Galaxy, while disrupting into thin leading and trailing stellar arms. In this talk, I will show that a previous encounter between the Pal 5 stellar stream and the Milky Ways Galactic bar has punched a hole in the stream, which can explain new observations finding that leading arm of Pal 5 appears to be a lot shorter than the trailing arm. My work implies that caution should be applied before interpreting stream gaps as evidence for dark matter subhalos. Additionally, I will discuss ongoing work on the Milky Ways Galactic bar and what we might learn about the bar through its interaction with stellar streams, through simulations of dwarf galaxies interacting with the Milky Ways disk and by using Gaia DR2.

    “The Chiral Anomaly in Dirac Semimetals”

    Location: Jadwin Hall, Room A10
    Time: 4:00 PM
    Speaker(s): Nai Phuan Ong, Princeton University

    Description: I will talk about recent experiments on the chiral anomaly in Dirac semimetals. In field theory, Dirac fermions of zero mass must segregate into left- and right-handed populations that do not ever mix. In this limit, chiral symmetry (handedness) is a global symmetry of the Lagrangian. However, quantum effects induced by coupling to a vector gauge field kill the symmetry. This is known as the chiral (or axial) anomaly. The first example appeared (1968) in the decay of neutral pions into 2 photons (the Adler-Bell-Jackiw anomaly). Since then, anomalies have been implicated in many important problems, e.g. the $U(1)_A$ problem, renormalizability of the electroweak theory, and the fermion-doubling problem in lattice QCD. It is also directly related to the Atiyah-Singer index theorem. In 1983, Nielsen and Ninomiya predicted that the chiral anomaly should be observable as well in bulk semimetals that feature protected 3D Dirac cones. Breaking of time-reversal invariance in a magnetic field B converts the Dirac electrons in a semimetal to Weyl fermions. The chiral nature of the Weyl fermions become manifest in the lowest Landau level (in intense B). An electric field applied parallel to B shifts the left and right-moving branches to produce an axial current. I will describe experiments on $Na_3Bi$ and GdPtBi which show the dramatic emergence of the anomaly, and focus on issues peculiar to the anomaly in crystals. I will describe a litmus test that sharply distinguishes this quantum effect from (classical) artifacts caused by current jetting.

    Location: Princeton University, Peyton Hall, Grand Central
    Time: 11:00 AM
    Speaker(s): Discussion Leader TBA

    Description: Each week, we hold a relatively informal seminar/discussion series in Peyton Hall with an emphasis on extra-galactic and large-scale structure astrophysics. During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is projected onto a large screen, and a guest explains the paper, section by section, in greater detail than may be explained within the text of the article. To aid with discussion, only the article PDF is presented -- no powerpoint-style slides. Galread discussions are very friendly and interactive. If you would like to present at Galread, please contact Andy Goulding (goulding[at]astro.princeton.edu) or Jenny Greene (jgreene[at]astro.princeton.edu). The group's website is: http://web.astro.princeton.edu/events/seminars/galread. The discussion paper is here:

    Time: 12:30 PM
    Speaker(s): Everyone Welcome

    Description: The Monday Planet Lunch will be held weekly. We discuss recent papers from astro-ph and hear from the occasional exoplanet visitor. Graduate students are particularly encouraged to attend. The format will be informal and inclusive, spanning at a minimum exoplanets, the solar system, and astrobiology. Moreover, we plan on discussing multiple topics each time we meet, and not to tether a lunch to one organized presentation each sitting. The purpose is to foster wide-ranging and cross-fertilizing interaction and to keep the local community up to date on developments across the spectrum of associated activities. Joel Hartman is the organizer.
