The black hole mass spectrum from single and binary stars by Mario Spera (Marie
Curie Global Fellow, Northwestern University, USA)
Thursday 10 Jan 2019, 16:00 → 17:00 Europe/Rome
Aula Conversi (Dip. di Fisica - Edificio G. Marconi)
Description
Since the first observation of the gravitational-wave signal from two BHs
with mass larger than 25 Msun (GW150914) by the LIGO interferometers, ten
additional BH mergers were observed, and six of them have BHs with mass
larger than 30 Msun. The models that predict the formation and evolution of
binary BHs (BBHs) are still uncertain. In this talk, I will present the BH
mass spectrum and the statistics of BBHs obtained with the SEVN code. SEVN
is our new population synthesis code that implements up-to-date stellar
evolution prescriptions. I will also discuss how stellar dynamics shapes
the distribution of merging BBHs in star clusters and its implications on
the merger rates of BBHs.
