Astronomy Seminar Series artwork

A Good Hard Look at Cosmic Supermassive Black-Hole Growth

11:30 am – 12:30 pm (CDT)Streaming Live

Speaker: Niel Brandt (Penn State University)Host: Jonelle Walsh

The 7 Ms Chandra X-ray Observatory exposure on the Chandra Deep Field-South (CDF-S) has provided the most sensitive extragalactic X-ray survey by a wide margin. About 1050 X-ray sources have been detected, primarily distant active galactic nuclei (AGNs) and starburst/normal galaxies. The unmatched deep multiwavelength coverage for these sources allows s... read more  »

Roads Not Taken

11:30 am – 12:30 pm (CDT)Streaming Live

Speaker: Cameron Liang (Institute for Defense Analysis)Host: Stephanie Ho

I will discuss some highlights of research topics in my graduate school and postdoc experience. I will discuss my perspective and the technical skills I gained along the way. I will focus on my experience transitioning out of academia, and how my background helps transition into the world of data science and my current research role.      ... read more  »

How Bright is the Radio Sky? (We Don’t Know) (yet)

4:00 pm (CDT)Hawking Auditorium

Speaker: Jack Singal (University of Richmond)Host: Doojin Kim

The actual level of diffuse radio emission on our sky is surprisingly uncertain.  Almost all investigations that depend on understanding the radio sky, including cosmic microwave background and 21 cm cosmology foregrounds, rely on just one measurement – the 408 MHz Haslam map from the 1980s, which traces its absolute calibration to highly uncerta... read more  »

Accelerating Solitons

3:00 pm – 4:00 pm (CDT)MIST M108

Speaker: Andrew Royston (Pennsylvania State University)Host: Falk Hassler

We show that the leading semiclassical behavior of soliton form factors at arbitrary momentum transfer is controlled by solutions to a new wave-like integro-differential equation that describes solitons undergoing acceleration. We work in the context of two-dimensional linear sigma models for concreteness, but our methods are purely semiclassical and ge... read more  »

When Stars Go Nonlinear: Large Amplitude Tides and Stellar Oscillations

11:30 am – 12:30 pm (CDT)

Speaker: Nevin Weinberg (University of Texas, Arlington)Host: Jonelle Walsh

Tides significantly impact the structure, evolution, and fate of many types of close binary systems, including short-period exoplanets, stellar binaries, and coalescing binary neutron stars.  In many of these systems, the tide’s amplitude is so large that it cannot be treated as a small, linear perturbation to the background star.  In this talk, ... read more  »

Linearized Supergeometry of 11D,N =1⁄8 Superspace

3:00 pm – 4:00 pm (CDT)MIST M108

Speaker: Anindya Sengupta (Texas A&M University)Host: Falk Hassler

In 1978, Cremmer, Julia, and Scherk wrote down a (component) theory of eleven-dimensional Supergravity. Soon, in 1980, Brink and Howe gave a superspace formulation of this theory. The component theory required that dynamical fields to be on-shell for the closure of 11D,N=1 Supersymmetry. The same on-shell requirement followed from the Bianchi identities... read more  »

Prospects for Observing Exoplanets in the Coming Years with JWST

11:30 am – 12:30 pm (CDT)Hawking Auditorium

Speaker: Caroline Morley (University of Texas, Austin)Host: Stephanie Ho

As exoplanet astronomers, we currently stand at a threshold: with current and near-future discoveries from TESS, we have now discovered many of the nearby planets we share our neighborhood with. The Hubble and Spitzer space telescopes, as well as dedicated ground-based efforts, have provided a taste of the diversity of atmospheres these worlds have. The... read more  »

Black Holes in the Early Universe

4:00 pm – 5:00 pm (CDT)Hawking Auditorium

Speaker: Dan Hooper (University of Chicago)Host: Doojin Kim

Cosmology textbooks typically assume that the early universe was dominated by relativistic particles. But if even a relatively small number of black holes were created after inflation, they would make up an increasingly large fraction of the total energy density as space expands. I’ll argue that it is well-motivated to scenarios in which the early uni... read more  »

Worldsheet Correlators in AdS3

3:00 pm – 4:00 pm (CDT)Streaming Live

Speaker: Lorenz Eberhardt (Institute for Advanced Study)Host: Falk Hassler

We revisit the computation of string correlation functions in AdS3 with pure NS-NS flux from a worldsheet point of view. These correlators contain all the perturbative information about the spacetime CFT and the existence of winding strings in AdS3 makes them very rich. We propose a solution to the problem of computing these correlators. The winding cor... read more  »
