Ajith (ICTS-TIFR) Abstract Type : Poster Abstract Category : Extragalactic astronomy Abstract : Coalescing binary systems comprising compact objects (neutron stars or black holes) are believed to be the primary sources of gravitational waves (GWs) for ground-based GW detectors like LIGO. These compact objects are the end products of stellar evolution. One can use the method of population synthesis to create astrophysical models predicting the evolution of these binary stars; here we consider the case of binaries in galactic fields. Since several physical and astrophysical processes governing binary evolution are not very well understood, different models differ greatly in their predictions of coalescence rates as well as the mass and spin distributions of compact objects. GW observations of compact binaries can constrain population models, shedding light on the uncertain physics and astrophysics of compact binary evolution. In this talk I will discuss the use of Bayesian statistical inference to extract the properties of coalescing compact binary populations, and to constrain population synthesis models. |
