Common origin for black holes in both high mass X-ray binaries and gravitational-wave sources
K. Belczynski, C. Done, S. Hagen +2
Black-hole (BH) high-mass X-ray binary (HMXB) systems are likely to be the progenitors of BH-BH mergers detected by LIGO/Virgo/KAGRA (LVK). Yet merging BHs reach higher masses ($\s…
The connection between merging double compact objects and the Ultraluminous X-ray Sources
Samaresh Mondal, Krzysztof Belczyński, Grzegorz Wiktorowicz +2
We explore the different formation channels of merging double compact objects (DCOs: BH-BH/BH-NS/NS-NS) that went through a ultraluminous X-ray phase (ULX: X-ray sources with appar…
Impact of inter-correlated initial binary parameters on double black hole and neutron star mergers
J. Klencki, M. Moe, W. Gladysz +3
The distributions of the initial main-sequence binary parameters are one of the key ingredients in obtaining evolutionary predictions for compact binary (BH-BH / BH-NS / NS-NS) mer…
On the accuracy of mass measurement for microlensing black holes as seen by Gaia and OGLE
Krzysztof A. Rybicki, Łukasz Wyrzykowski, Jakub Klencki +3
We investigate the impact of combining Gaia astrometry from space with precise, high cadence OGLE photometry from the ground. For the archival event OGLE3-ULENS-PAR-02, which is li…
Black Hole Binaries Dynamically Formed in Globular Clusters
Dawoo Park, Chunglee Kim, Hyung Mok Lee +2
We investigate properties of black hole (BH) binaries formed in globular clusters via dynamical processes, using direct N-body simulations. We pay attention to effects of BH mass f…
