Institute for Advanced Study Informal Astrophysics Seminar - Title & Abstract Updated
“Time-Domain Approaches to Investigating the Tension in H0”

Location: Bloomberg Hall, Astrophysics Library
Time: 11:00 AM
Speaker(s): Danny Goldstein, California Institute of Technology

Description: State-of-the-art local and primordial measurements of the Hubble constant (H0) are currently in tension at the 4.4 sigma level. New physics and systematic errors have been invoked as potential explanations. I will discuss two new, independent techniques for measuring H0 from time-domain astronomy that can help distinguish between these and other scenarios. The first is to use time delays from strongly gravitationally lensed supernovae to constrain H0 geometrically. The second is to construct a distance-redshift relation using electromagnetic counterparts to gravitational wave events. I will describe experimental efforts that are currently underway to carry out both of these measurements, namely the Zwicky Transient Facility lensed supernova search and the Dark Energy Camera neutron star merger follow-up program.

Joint Princeton University Thunch & Gravity Group Lunch Seminar - Updated
“Implications for the Stochastic Gravitational Wave Background from a Massive Quasar-binary”

Time: 12:30 PM
Speaker(s): Kris Pardo, Princeton University

Description: The collective inspirals of very close-separation supermassive black holes (SMBHs) are expected to produce a stochastic gravitational wave background (GWB) at nHz frequencies, which is accessible to pulsar timing arrays. However, we have yet to detect this background or find any SMBH binaries that are sufficiently massive or at small enough separations to contribute appreciably to the GWB. Using Hubble Space Telescope imaging, we have identified a pair of rapidly-growing supermassive black holes (M>4.e8 solar masses) at z=0.2 that are separated by only 400 parsecs. While this pair is not currently in the GW-emission regime, it points to a population of SMBH pairs that should have merged by today, unless there is a final parsec problem. Using estimates for the number density of such sources, we place limits on the expected GWB amplitude. I'll discuss the issues surrounding these calculations and how we can expect to learn more about the GWB and SMBH dynamics as we search for more of these SMBH pairs.

Lunch will be available outside the auditorium starting at 12pm on Thursday. If you would prefer to eat during the talk, you are welcome to do so, but we ask that you clean up after yourselves even more carefully than you normally would, the Physics colloquium happening in this same room a few hours later.

Lunch will be catered by IQuisine; sign up for it by 12 pm Wednesday here:

Rutgers University Astrophysics Seminar
“The Origin of Multiphase Galaxy Outflows”

Location: Serin Hall, Room 401
Time: 1:30 PM
Speaker(s): Evan Schneider, Princeton University
Note: Refreshments to follow in room 332W.

Description: Star-forming galaxies are often observed to host galactic winds - gas that is flowing out of the galaxy in phases ranging from cold molecular clouds to hot X-ray emitting plasma. While these multiphase outflows are routinely observed, theoretically constraining their origin and evolution has proven difficult. Explaining the prevalence and velocities of the cool ionized phase (T~10^4 K) in particular poses a challenge. In this talk, I will discuss a potential dual origin for this cool gas. Through a series of extremely high-resolution simulations run with the GPU-based Cholla code, I will show that in high star formation surface density systems, dense disk gas can be pushed out by the collective effect of clustered supernovae, explaining the low-velocity material. Simultaneously, shredding and mixing of these clouds increases the density of the hot phase of the wind, leading to large-scale radiative losses that produce high velocity cool gas. In addition to explaining the nature of outflows themselves, these multiphase winds could potentially be a source of the cool photo-ionized gas that is found in abundance in galaxy halos.

Location: Princeton University, Peyton Hall, Grand Central
Time: 11:00 AM

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).

Princeton University/Institute for Advanced Study Early Universe/Cosmology Lunch Discussion
“Inhomogeneous Initial Conditions and the Start of Inflation”

Location: Institute for Advanced Study, West Building, West Seminar Room
Time: 12:30 PM
Speaker(s): Patrick John Fitzpatrick, Massachusetts Institute of Technology

Description: The robustness of inflation to inhomogeneous initial conditions for matter fields and the spacetime metric is under investigation. If inflationary expansion fails to begin under sufficiently inhomogeneous initial conditions, such that inflation requires fine-tuning of its initial state to occur, then its naturalness is challenged. I will present results for the range of initial conditions which give rise to inflation, based on numerical calculations which evolve the equations of motion of the scale factor and the inflaton field coupled to its quantum fluctuations and metric perturbations through a well-defined set of nonlinear interactions in the Hartree approximation. These results address to what extent inflation can occur under inhomogeneous initial conditions for a few standard slow-roll single-field inflationary models, in calculations which include effects of gravitational back-reaction of perturbations on the background dynamics and on the perturbations themselves, and which have wide applications beyond the inflationary models I will present. Our findings are consistent with recent simulations involving full (3+1) numerical relativity. However, by relying on certain well-studied approximations, our numerical approach can be applied more efficiently to a wide range of models, and can track the evolution of perturbations across a wide range of scales, thereby complementing the recent numerical-relativity simulations.

Organizers are Jo Dunkley, Princeton University, and Matias Zaldarriaga, Institute for Advanced Study. The lunch will be held either at Princeton University or the Institute for Advanced Study. Check the calendar for the meeting location. This week's meeting is at the Institute for Advanced Study. Attendees can bring their own lunch or stop at the IAS Dining Hall. The West Seminar room is in a building which is a short walk from the main dining area.

Princeton University Data Science / COMPASS Seminar
“Improving Bayesian Hierarchical Modeling for Supernova Cosmology via Selection Effects”

Location: Peter B. Lewis Science Library, Visualization Lab, Rm. 347
Time: 4:00 PM
Speaker(s): Lucas Makinen, Princeton University

Description: Distant supernovae are less likely than closer ones to be selected in astronomical surveys. To avoid the bias this phenomena introduces to our estimation of Dark Energy parameters, we incorporate selection effects into a hierarchical probabilistic framework, which estimates these parameters as a function of data and prior knowledge. The project is multidisciplinary by nature, featuring a combination of cosmology, astrophysics, data science, and computational optimization. The current goal is to calibrate our inference machinery to be able to handle the newly-released Dark Energy Survey data.

Every week we discuss data science methods and applications from papers, reviews, software releases, etc. We also have demos for useful/fancy methods by locals and visitors through the COMPASS program. The setting is informal. Material should be presented directly from the source or on the white board, demos should be hands-on. We collect links to documents, source code, tutorials, etc. for later perusal in this github repo. If you would like to present at the data science seminar, please contact the organizers Peter Melchior (melchior[at]astro.princeton.edu), Adrian Price-Whelan (adrn[at]astro.princeton.edu), Christina Kreisch (ckreisch[at]astro.princeton.edu), Lachlan Lancaster (lachlanl[at]princeton.edu).

“The Black Hole Shadow in M87”

Location: Princeton University, Peyton Hall, Auditorium, Room 145
Time: 11:00 AM
Speaker(s): Dan Marrone, University of Arizona
Note: Coffee and refreshments are available from 10:15 am in Peyton Hall Common Room.

Description: The Event Horizon Telescope (EHT) is an international collaboration to observe black holes at horizon-scale resolution. The EHT uses the technique of very long baseline interferometry (VLBI) and submillimeter telescopes all over the globe to perform VLBI experiments at 1mm wavelength, where we expect to resolve the event horizons of two targets, M87* and SgrA*. In 2017, the EHT performed its first experiment, using eight observatories at six geographic locations. In this talk I will report on the first results from that experiment, the image of the nuclear black hole in M87. From these data we have improved our understanding of this source, measured its mass, and provided a new test of General Relativity. I will also describe the path to these results and the next steps for this project.

“Search Optimization, Natural Selection and Self-Organized Criticality on the Landscape”

Time: 4:00 PM
Speaker(s): Justin Khoury, University of Pennsylvania

Description: The most pressing fine-tuning puzzles of the Standard Model the cosmological constant and weak hierarchy problems, as well as the Higgs metastability  can all be understood as problems of near criticality. I will present a natural selection mechanism based on search optimization on the string landscape. The working assumption is that cosmological evolution on the multiverse has occurred for a finite time, much shorter than the exponentially-long global mixing time for the landscape. I will argue this imposes a strong selection pressure among hospitable vacua, favoring those that lie in optimal regions where the search algorithm is efficient. This satisfies the basic requirements for natural selection: a diverse gene pool, offered ab initio by the landscape; vacuum replication through cosmological expansion; and competition for a finite resource, namely the fraction of comoving volume. Optimality is defined by two competing requirements: search efficiency, which requires minimizing the mean-first passage time, and sweeping exploration, which requires recurrent random walks. Optimal landscape regions reach a compromise by lying at the critical boundary between recurrence and transience, thereby realizing the idea of self-organized criticality. The framework makes concrete phenomenological predictions: 1. The expected lifetime of our universe is ~10^{130} years, consistent with current Standard Model metastability estimates; 2. The SUSY breaking scale should be nearly Planckian; and 3. The predicted cosmological constant is M_Pl^4/N, which can account for the inferred vacuum energy if our optimal region contains N ~10^{120} vacua. Importantly, these predictions do not rely on anthropic reasoning and instead follow readily from optimality.

“Discovering the Electro-Weak Force, Seeing a Supernova Explode, Peering Inside the Sun, & Watching Neutrinos Oscillate”

Time: 4:00 PM
Speaker(s): Lawrence Sulak, Boston University

Description: Cosmological hypotheses and oracular dreams of grandly unifying all the forces of nature foretold: neutrinos might weigh a tiny bit, those elusive particles might blow up stars, and the protons (and your ashes) would transform into light in $10^29$ years. Indeed, that man can live to 100, without the radioactivity in his bones killing him, proves that nucleons survive for at least $10^26$ yearsfar longer than the big-bang light in the sky which dates our universe to a mere $10^10$ years. Testing the unification theories demanded new technologies to search for ultra-rare interactions. The pioneering experiment would need fast, isochronous, single photoelectron light sensors; a $N_2$ calibration laser; reverse osmosis water; and fast, inexpensive waveform digitizersushering in an era of massive, totally-active, Cherenkov ring-imaging calorimeters. Successive detectors morphed the target medium of the initial detector (ultrapure water) into heavy water, seawater, solid water, and even clear and scintillating oil. The two neutrino sources for the seminal experiment -- the atmosphere and Supernova 1987a -- evolved to include near and far accelerators, our sun, and nuclear reactors.I will relate the demise of the simplest unifying theory while tracing the tortuous path from a deficit of atmospheric neutrinos to a definitive observation of neutrino oscillationnow enabling ambitious dreams of tomorrow: untangling the mystery of CP violation and hypothesizing the lepto-genesis of the cosmos.This lecture is dedicated to the memory of physicist Val Fitch, Princeton inventor of an early water Cherenkov counter and unraveler of CP invariance.Twitter: #PrincetonPhyColloq

“MUSE and GRAVITY”

Location: Bloomberg Hall, Astrophysics Library
Time: 11:00 AM
Speaker(s): Tim de Zeeuw, Leiden Observatory and Max Planck Institute for Extraterrestrial Physics

Description: This informal seminar will highlight results obtained recently with the transformational instruments MUSE and GRAVITY on ESOs Very Large Telescope at Paranal. For MUSE, the focus will be on an ongoing study of the internal dynamics, stellar populations and slope of the initial mass function of 33 bright galaxies within the virial radius of the Fornax cluster. The results connect the properties of the stellar populations to the internal dynamical structure. They provide insight into the structure of the cluster, which is dominated by the gravitational potential of the central galaxy NGC1399, and serve as a benchmark for (simulations of) the assembly and evolution of galaxies in a cluster environment. GRAVITYs interferometric measurements with the four 8m telescopes include the detection of the gravitational redshift and relativistic transverse Doppler motion in the highly-elliptical 16-year-period orbit of the star S2 around Sgr A*, the detection of looped motion of flares in Sgr A* at 30% of the speed of light near the innermost stable circular orbit of the central black hole, the measurement of the size of the broad-line region in 3C273 as well as a direct spectroscopic measurement of the properties of the atmosphere of a bright young planet orbiting HR8799e.
