Potential kick velocity distribution of black hole X-ray binaries and implications for natal kicks

Potential kick velocity distribution of black hole X-ray binaries and implications for natal kicks

We use Very Long Baseline Interferometry to measure the proper motions of three black hole X-ray binaries (BHXBs). Using these results together with data from the literature and Gaia-DR2 to collate the best available constraints on proper motion, parallax, distance and systemic radial velocity of 16 BHXBs, we determined their …
