Explaining LIGO's observations via isolated binary evolution with natal kicks
D. Wysocki, D. Gerosa, R. O'Shaughnessy +5
We compare binary evolution models with different assumptions about black-hole natal kicks to the first gravitational-wave observations performed by the LIGO detectors. Our compari…
The evolutionary roads leading to low effective spins, high black hole masses, and O1/O2 rates of LIGO/Virgo binary black holes
K. Belczynski, J. Klencki, C. E. Fields +31
All ten LIGO/Virgo binary black hole (BH-BH) coalescences reported from the O1/O2 runs have near zero effective spins. There are only three potential explanations of this fact. If…
The Effect of Pair-Instability Mass Loss on Black Hole Mergers
K. Belczynski, A. Heger, W. Gladysz +9
Mergers of two stellar origin black holes are a prime source of gravitational waves and are under intensive investigations. One crucial ingredient in their modeling has so far been…
Comparison of LIGO/Virgo upper limits with predicted compact binary merger rates
Krzysztof Belczynski, Michal Dominik, Serena Repetto +2
We compare the current LIGO/Virgo upper limits on double compact object volumetric merger rates with our theoretical predictions. Our optimistic models are a factor of 3 below the…
