We discuss the method, and potential systematic effects therein, used for measuring the
mass of stellar-mass black holes in X-ray binaries. We restrict our discussion to the method …

We report spectroscopic and photometric follow-up of a dormant black hole (BH) candidate
from Gaia DR3. The system, which we call Gaia BH2, contains a∼ 1 M⊙ red giant and a …

Aims. During the last~ 50 years, the population of black hole candidates in X-ray binaries
has increased considerably, with 59 Galactic objects being detected in transient low-mass X …

With the advent of more sensitive all-sky instruments, the transient universe is being probed
in greater depth than ever before. Taking advantage of available resources, we have …

We use dynamical mass measurements of 16 black holes in transient low-mass X-ray
binaries to infer the stellar black hole mass distribution in the parent population. We find that …

We perform a Bayesian analysis of the mass distribution of stellar-mass black holes using
the observed masses of 15 low-mass X-ray binary systems undergoing Roche lobe overflow …

We explore possible systematic errors in the mass measurements of stellar mass black
holes (BHs). We find that significant errors can arise from the assumption of zero or constant …

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 …

INTEGRAL is an ESA mission in fundamental astrophysics that was launched in October
2002. It has been in orbit for over 18 years, during which it has been observing the high …

We extend our recent work on black hole spin in X-ray binary systems to include an analysis
of 189 archival NuSTAR observations from 24 sources. Using self-consistent data reduction …
