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 the observations are best described by a narrow mass distribution at 7.8 {+-} 1.2 M{sub sun}. We identify a selection effect related to the choice of targets for optical follow-ups that results in a flux-limited sample. We demonstrate, however, that this selection effect does not introduce a bias in the observed…

The Origin of Black Hole Spin in Galactic Low-Mass X-ray Binaries
Galactic field black hole (BH) low-mass X-ray binaries (LMXBs) are believed to form in situ via the evolution of isolated binaries. In the standard formation channel, these systems survived a common
Constraining the formation of black holes in short-period black hole low-mass X-ray binaries
The formation of stellar mass black holes is still very uncertain. Two main uncertainties are the amount of mass ejected in the supernova event (if any) and the magnitude of the natal kick the black
Mass Measurements of Black Holes in X-Ray Transients: Is There a Mass Gap?
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 emission from the
On the formation of galactic black hole low-mass X-ray binaries
Currently, there are 24 black hole (BH) X-ray binary systems that have been dynamically confirmed in the Galaxy. Most of them are low-mass X-ray binaries (LMXBs) comprised of a stellar-mass BH and a
BlackCAT: A catalogue of stellar-mass black holes in X-ray transients
During the last ~50 years, the population of black hole candidates in X-ray binaries has increased considerably with 59 Galactic objects detected in transient low-mass X-ray binaries, plus a few in
The closest black holes
Starting from the assumption that there is a large population (> 10^8) of isolated, stellar-mass black holes (IBH) distributed throughout our galaxy, we consider the detectable signatures of
The mass distribution of stellar-mass black holes
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 and 5 high-mass,
On the Spin of the Black Hole in IC 10 X-1
The compact X-ray source in the eclipsing X-ray binary IC 10 X-1 has reigned for years as ostensibly the most massive stellar-mass black hole, with a mass estimated to be about twice that of its
Observational Evidence for Black Holes
Astronomers have discovered two populations of black holes: (i) stellar-mass black holes with masses in the range 5 to 30 solar masses, millions of which are present in each galaxy in the universe,
Measuring the Black Hole Mass Spectrum from Redshifts of aLIGO Binary Merger Events
The binary black hole merger events observed by the Advanced LIGO (aLIGO) and VIRGO collaboration can shed light on the origins of black holes. Many studies based on black hole stellar origins have

THE MASS DISTRIBUTION OF STELLAR BLACK HOLES
We examine the distribution of masses of black holes in transient low-mass X-ray binary systems. A Bayesian analysis suggests that it is probable that six of the seven systems with measured mass
Theoretical black hole mass distributions
We derive the theoretical distribution function of black hole masses by studying the formation processes of black holes. We use the results of recent two-dimensional simulations of stellar core
Masses of stellar black holes and testing theories of gravitation
The paper analyzes the mass distribution of stellar black holes derived from the light and radial-velocity curves of optical stars in close binary systems using dynamical methods. The systematic
A 15.65-solar-mass black hole in an eclipsing binary in the nearby spiral galaxy M 33
TLDR
It is found that the common envelope phase could not have occurred in M 33 X-7 unless the amount of mass lost from the progenitor star during its evolution was an order of magnitude less than what is usually assumed in evolutionary models of massive stars.
Compact Stellar X-Ray Sources: Black hole binaries
4.1.1 Scope of this review We focus on 18 black holes with measured masses that are located in X–ray binary systems. These black holes are the most visible representatives of an estimated ∼300

We investigate the dependence of observational properties of black hole X-ray binaries on the inclination angle i of their orbits. We find the following: (1) Transient black hole binaries show no
An unusually massive stellar black hole in the Galaxy
TLDR
A direct measurement of the orbital period and mass function of GRS1915+105 is reported, which allow us to deduce a mass of 14 ± 4 M[circdot] for the black hole.
THE FIRST ACCURATE PARALLAX DISTANCE TO A BLACK HOLE
