Title: Impact of Central Massive Black Hole Accretion on the Event Horizon, Host Galaxy, and Beyond Abstract: Astrophysical black holes are surprisingly simple physical objects. Their gravitational field can be fully described by two parameters: mass and spin. We cannot directly observe black holes as no light escapes from the event horizon. However, we can … Continue reading "CRA Seminar: Labani Mallick (U Manitoba) Virtual"

Title: Transcending the Limits of Theoretical Physics with Deep Learning Abstract: Astronomy has recently experienced a profound transformation, driven by the acquisition of extensive datasets generated by increasingly sophisticated instruments. … Continue reading "CRA Seminar: Yuan-Sen Ting (ANU)"

Title: Identification and characterization of GW bursts with the BayesWave algorithm for expanded GW detector networks Abstract:  The global gravitational-wave detector network currently consists of four interferometers: LIGO Hanford (H) and … Continue reading "Special CRA Seminar: Christine Lee (AU)"

TITLE: Gravitational wave and electromagnetic signatures of binary black holes with circumbinary gas ABSTRACT: Binary black holes (BHBs) embedded in dense gas hold the promise of so-called "multi-messenger astrophysics": when … Continue reading "CRA Seminar: Zoltan Haiman (Columbia, on sabbatical at GT)"

Title: “Trinity neutrino observatory: progress of the Demonstrator phase” Abstract: In this seminar, I will present the Trinity’s pioneering efforts in Earth-skimming tau neutrino detection. I delve into the evolution … Continue reading "CRA Seminar: Mariia Fedkevych (GT)"

Title: Going wider and deeper in the search for gravitational waves Abstract: Gravitational waves (GWs) are oscillations of spacetime itself due to strong dynamical gravity. Since its first detection by the Laser Interferometer Gravitational-wave Observatory (LIGO) in 2015, a network of the ground-based GW detectors detected 90 signals from compact binary mergers by 2020. In … Continue reading "Leo Tsukada -Penn State Un"

Title: Unveiling the TeV Sky in Neutrinos and Gamma rays Abstract: The search for the origin of cosmic rays as well as the signatures of new physics, are closely tied to precision measurements, of both point and diffuse sources of very-high-energy Galactic and extra-galactic emission. The IceCube Neutrino Observatory has been observing a bright, diffuse … Continue reading "Mehr Un Nisa (MSU)"

Title: Insights from Local Simulations of Accretion Disk Coronae: Two-temperature effects, thermal conduction, and radiation transport Abstract: I will present a series of local accretion disk models, i.e., stratified shearing-box magnetohydrodynamic (MHD) simulations, for radiatively efficient accretion flows (REFs), which for the first time, include the effects of field-aligned free-streaming thermal conduction and radiation transport. … Continue reading "CRA Seminar: Chris Bambic Princeton UN"
