"Multimessenger astronomy of compact binaries from the vantage point of computational gravity"


Prof. Vasileios Paschalidis , University of Arizona
[Host: Kent Yagi]
ABSTRACT:

We live in an exciting era where strong-field gravity has become a central pillar in the study of astrophysical sources.   For the first time in history the detection of gravitational waves and simultaneous electromagnetic signals (multimessenger astronomy) from the same source have the potential to solve some of the most long-standing problems in fundamental physics and astrophysics. Computational gravity plays an important role in the success of the multimessenger astronomy program. Using the vantage point of computational gravity, in this talk we will we focus on how observations of colliding neutron stars can teach us about the state of matter at densities greater than the nuclear density, and with a critical eye assess what we have learnt so far from the first observation of a binary neutron star (event GW170817). We will also discuss how multimessenger detection of collisions of binary black holes may inform us about their environments andthe nature of black holes.
