Title: How Black Holes Dine above the Eddington "Limit" without Overeating or Excessive Belching Abstract The study of super-Eddington accretion is essential to our understanding of the growth of super-massive … Continue reading "CRA seminar: Prof. Shane Davis (University of Virginia)"

Probing neutron star physics with gravitational wave detections The recent detection of the binary neutron star merger event (GW170817) has marked the beginning of multi-messenger astronomy with gravitational waves. In … Continue reading "CRA Seminar: Prof. Huan Yang (Perimeter Institute)"

Observational tests of general relativity with black hole inspiral, coalescence, and ringdown Prof. Lee Samuel Finn (Penn State University) Website: https://www.phys.psu.edu/people/lsf5 Abstract: As far as it has been tested, general relativity “works”; however, tests of general relativity are spotty in their coverage and - especially in the dynamical regime - leave much to be desired … Continue reading "CRA Seminar: Lee Samuel Finn (Penn State University)"

Title: “I Like to Myself Believe That Planet 5 Turns Slowly” Abstract: Within the general framework of the core-nucleated accretion theory of giant planet formation, the conglomeration of massive gaseous envelopes is facilitated by a transient period of rapid accumulation of nebular material. While the concurrent build-up of angular momentum is expected to leave newly … Continue reading "CRA seminar: Prof. Konstantin Batygin (Caltech)"
