Globular star clusters contain thousands to millions of old stars packed within a region only tens of light years across. Their high stellar densities make it very probable that their member stars will interact or collide. There has accordingly been considerable debate about whether black holes should exist in these star clusters. Some theoretical work suggests that dynamical processes in the densest inner regions of globular clusters may lead to the formation of black holes of ∼1,000 solar… Expand
Two stellar-mass black holes in the globular cluster M22
The identification of two black holes in one cluster shows that ejection of black holes is not as efficient as predicted by most models, and it is argued that M22 may contain a total population of ∼5–100 black holes, which could arise from heating produced by the black holes. Expand
The Dynamical Evolution of Stellar Black Holes in Globular Clusters
Our current understanding of the stellar initial mass function and massive star evolution suggests that young globular clusters may have formed hundreds to thousands of stellar-mass black holes, theExpand
A new globular cluster black hole in NGC 4472
We discuss CXOU 1229410+075744, a new black hole candidate in a globular cluster in the elliptical galaxy NGC 4472. By comparing two Chandra observations of the galaxy, we find a source that variesExpand
Retention of Stellar-Mass Black Holes in Globular Clusters
Globular clusters should be born with significant numbers of stellar-mass black holes (BHs). It has been thought for two decades that very few of these BHs could be retained through the clusterExpand
Spectroscopy of Binaries in Globular Clusters
The natural constants in the universe are adjusted so that dense and massive star forming regions can end up in gravitational bound star clusters, called globular clusters. These objects are found inExpand
Effects of Stellar-Mass Black Holes on Massive Star Cluster Evolution
Abstract Recent observations have revealed the existence of stellar mass black hole (BH) candidates in some globular clusters (GC) in the Milky Way and in other galaxies. Given that the detection ofExpand

It is shown that these candidate systems could instead be ultracompact X-ray binaries (UCXBs) in which a neutron star accretes from a white dwarf, with slightly earlier evolutionary stage of known globular cluster UCXBs such as 4U 1820-30. Expand
Gas depletion in primordial globular clusters due to accretion on to stellar-mass black holes
We consider the effect of compact stellar remnants on the interstellar medium of a massive star cluster following the initial burst of star formation. We argue that accretion onto stellar-mass blackExpand
A detached stellar-mass black hole candidate in the globular cluster NGC 3201
As part of our massive spectroscopic survey of 25 Galactic globular clusters with MUSE, we performed multiple epoch observations of NGC 3201 with the aim of constraining the binary fraction. In thisExpand
Relativistic Binaries in Globular Clusters
This discussion of globular cluster evolution will focus on the processes that boost the production of tight binary systems and the subsequent interaction of these binaries that can alter the properties of both bodies and can lead to exotic objects. Expand


Stellar black holes in globular clusters
FOLLOWING the discovery of X-ray sources in globular clusters, the accretion of matter onto a central massive black hole was suggested1–3 as a possible explanation. Subsequently, it was found4,5 thatExpand
Production of intermediate-mass black holes in globular clusters
The discovery of numerous non-nuclear X-ray point sources with luminosities L>1039 erg s−1 in several starburst galaxies has stimulated speculation about their nature and origin. The strongExpand
Primordial black holes in globular clusters
IT HAS recently been recognized1 that significant numbers of medium-mass black holes (of order 10 solar masses) should form in globular clusters during the early stages of their evolution. Here weExpand
Could Black Hole X-Ray Binaries Be Detected in Globular Clusters?
The implications of the presence of an ∼1 stellar-mass black hole at the center of a dense globular cluster are considered, and it is found that BH X-ray binaries formed through tidal capture would be persistent, bright Xray sources. Expand
The globular cluster mass/low mass X-ray binary correlation: implications for kick velocity distributions from supernovae
Optical and X-ray studies of six nearby galaxies show that the probability a globular cluster will be an X-ray source is consistent with being linearly proportional to its mass. We show that thisExpand
The low-mass X-ray binary-globular cluster connection in NGC 4472
We have analyzed the low-mass X-ray binary (LMXB) candidates in a Chandra observation of the giant elliptical galaxy NGC 4472. In a region observed by the Hubble Space Telescope (HST), approximatelyExpand
The X-Ray Globular Cluster Population in NGC 1399
We report on the Chandra observations of the elliptical galaxy NGC 1399, concentrating on the X-ray sources identified with globular clusters (GCs). A large fraction of the 2-10 keV X-ray emission inExpand
