Merging black hole binaries: the effects of progenitor's metallicity, mass-loss rate and Eddington factor

Understand

The first four gravitational wave events detected by LIGO were all interpreted as merging black hole binaries (BHBs), opening a new perspective on the study of such systems.

• Here we use our new population-synthesis code MOBSE, an upgraded version of BSE (Hurley et al.
• 2002), to investigate the demography of merging BHBs.
• MOBSE includes metallicity-dependent prescriptions for mass loss of massive hot stars.
