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. This influx of data has opened up numerous new avenues for exploration in the field. However, this boon is accompanied by its own set of … 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 Livingston (L), Virgo (V) and KAGRA (K); the commissioning of LIGO India is also well underway. As the detector network continues to expand, it is … 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 they are detected both through gravitational waves (GWs) and electromagnetic (EM) observations, they will enable novel science.  This is true both for massive BHBs, whose … 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 of the Trinity project focusing on the Demonstrator phase, detailing its concept, development, and deployment. I will  discuss its operational challenges and highlights the instrument's … Continue reading "CRA Seminar: Mariia Fedkevych (GT)"
