Gravity Group Lunch Seminar | Oliver Philcox, PU "Have we exhausted the galaxy two-point function?"

Gravity Group Lunch Seminar | Oliver Philcox, PU "Have we exhausted the galaxy two-point function?"
Fri, Apr 2, 2021, 12:00 pm

Throughout the past three decades, the analysis of spectroscopic surveys has focussed around the two-point function of the galaxy overdensity field, masquerading either as the correlation function or the Fourier-space power spectrum. Today, theoretical interest has shifted towards other statistics, in particular the higher-point functions.

Condensed Matter Zoom Seminar | Eugene Demler, Harvard | "A new perspective on magnetic polarons from cold atoms"
Wed, Mar 31, 2021, 2:00 pm

What can we learn about a many-body system when we measure every constituent particle? Current experiments with ultracold atoms provide snapshots of many-body states with single particle resolution. I will present a recent application of this method to study magnetic polarons in antiferromagnetic Mott insulators.

Mon, Mar 22, 2021, 12:30 pm

A priori it would be surprising if all low-luminosity supermassive black holes, such as those in the centers of M87 and our own galaxy, had accretion disks aligned with their spin.

A PGI Special Seminar, "What's on the horizon? A discussion on the scientific prospects of the next-generation Event Horizon Telescope"
Wed, Mar 10, 2021, 3:00 pm

The Event Horizon Telescope (EHT) has produced the first image of a black hole for M87, opening the possibility to test general relativity and our understanding of black hole accretion and high-energy plasma physics. 

As the community is preparing to take the next steps, we want to discuss current challenges and future prospects of EHT...

PGI Virtual Seminar Series | Eliot Quataert, PU "Horizon-scale Modeling of Black Hole Accretion"
Mon, Mar 1, 2021, 12:30 pm

Abstract: In this talk, I will provide an overview of theoretical models of black hole accretion aimed primarily at non-specialists. I will focus in particular on efforts to understand the dynamics of, and radiation from, plasma in the near-horizon environment, both analytically and using numerical simulations.

Mon, Mar 1, 2021, 12:15 pm

Morphogenesis, the emergence of functional form in a developing organism, is one of the most remarkable examples of pattern formation in nature. Despite substantial progress, we still do not understand the organizational principles underlying the convergence of this process, across scales, to form viable organisms under variable conditions.
