Physics - Astrophysics, Gravitation, and Cosmology Seminar

Gravitational waves carry unique information about the most energetic events in the universe, including the merger of

binary  neutron stars or stellar-mass black holes.  These merger events are the end product of

still-weakly-constrained astrophysics: supernovae and the evolution of massive single and binary stars.  Simply

by opening a new window on the universe, gravitational wave detectors will identify many nearby mergers and measure many

of their properties.  Individually and as an ensemble, these measurements enable sometimes straightforward and sometimes

surprising inferences about the processes which formed them  (e.g., the range of black hole masses and spins; possibly,

which object formed first).  In this talk, I briefly summarize recent progress on the interpretation of detected compact

binary mergers.
