We investigate the impact of stellar rotation on the formation of black holes (BHs), by means of our population-synthesis code SEVN. Rotation affects the mass function of BHs in several ways. In massive metal-poor stars, fast rotation reduces the minimum zero-age main sequence (ZAMS) mass for a star to undergo pair instability and pulsational pair instability. Moreover, stellar winds are enhanced by rotation, peeling-off the entire hydrogen envelope. As a consequence of these two effects, the… Expand

Intermediate-mass black holes from stellar mergers in young star clusters
Intermediate-mass black holes (IMBHs) in the mass range $10^2\!-\!10^5\, \mathrm{M_{\odot }}$ bridge the gap between stellar black holes (BHs) and supermassive BHs. Here, we investigate theExpand

Modeling the outcome of supernova explosions in binary population synthesis using the stellar compactness
Following the collapse of their cores, some of the massive binary stars that populate our Universe are expected to form merging binaries composed of black holes and neutron stars. Gravitational-waveExpand
Hierarchical black hole mergers in young, globular and nuclear star clusters: the effect of metallicity, spin and cluster properties
We explore hierarchical black hole (BH) mergers in nuclear star clusters (NSCs), globular clusters (GCs) and young star clusters (YSCs), accounting for both original and dynamically assembled binaryExpand
Dynamics of binary black holes in low-mass young star clusters
Young star clusters are dynamically active stellar systems and are a common birthplace for massive stars. Low-mass star clusters (∼300–103 M⊙) are more numerous than massive systems and areExpand
Properties and Astrophysical Implications of the 150 M ⊙ Binary Black Hole Merger GW190521
The gravitational-wave signal GW190521 is consistent with a binary black hole (BBH) merger source at redshift 0.8 with unusually high component masses, ${85}_{-14}^{+21}$ M ⊙ and ${66}_{-18}^{+17}$ MExpand
Binary population synthesis models for core-collapse gamma-ray burst progenitors
Long-duration gamma-ray bursts (GRBs) are understood to be the final fate for a subset of massive, stripped envelope, rapidly rotating stars. Beyond this, our knowledge of the progenitor systems isExpand
Mass and Rate of Hierarchical Black Hole Mergers in Young, Globular and Nuclear Star Clusters
This work presents a fast semi-analytic approach to simulate hierarchical mergers in nuclear star clusters, globular clusters (GCs) and young star clusters (YSCs), finding that multiple formation channels are favored to reproduce the observed BBH population. Expand
Black Hole Mass Function of Coalescing Binary Black Hole Systems: Is there a Pulsational Pair-instability Mass Cutoff?
We analyze the LIGO/Virgo GWTC-2 catalog to study the primary mass distribution of the merging black holes. We perform hierarchical Bayesian analysis and examine whether the mass distribution has aExpand
GW190521: A Binary Black Hole Merger with a Total Mass of 150  M_{⊙}.
It is inferred that the primary black hole mass lies within the gap produced by (pulsational) pair-instability supernova processes, with only a 0.32% probability of being below 65  M⊙, which can be considered an intermediate mass black hole (IMBH). Expand
