On the effective spin-mass ratio relation of binary black hole mergers that evolved in isolation
Sambaran Banerjee, Aleksandra Olejak
The ground-based measurement of gravitational waves (GW) from merging binary black holes (BBH) allows independent determination of spins of stellar-remnant black holes (BH). The ob…
Stellar-mass black holes in young massive and open stellar clusters -- VII. Comparisons with gravitational-wave events until LVK-O4a and Gaia compact binaries
Sambaran Banerjee
Gravitational-wave (GW) detections by the LIGO-Virgo-KAGRA (LVK) observatories suggest multiple formation channels for GW compact binary mergers. Here I assess the role of young ma…
The velocity dispersion profile of nine open clusters in the solar neighborhood
Bingqian Ma, XiaoYing Pang, Sambaran Banerjee +2
We analyze the velocity dispersion profiles of nine open clusters in the solar neighborhood using kinematic data from Gaia DR 3, aiming to identify potential dynamical signatures o…
Stellar-mass black holes in young massive and open stellar clusters -- VI. Role of external galactic field
Sambaran Banerjee
Young massive clusters (YMC) and open clusters (OC) are widely considered as potential environments for assembling merging binary stellar-remnant black holes (BBH) via dynamical in…
The enigmatic origin of two dormant BH binaries: Gaia BH1 and Gaia BH2
Iwona Kotko, Sambaran Banerjee, Krzysztof Belczynski
The two systems, namely, Gaia~BH1 and Gaia~BH2, that have been confirmed as dormant (i.e., no X-ray emission detected) black hole (BH) - low-mass star binaries in the latest Gaia m…
