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 this cluster, we found one curious star at the main-sequence turn-off with radial velocity variations of the order of 100 km/s, indicating the membership to a binary system with an unseen component since no other variations appear in the spectra. Using an adapted variant of the generalized Lomb-Scargle…

A stellar census in globular clusters with MUSE: Binaries in NGC 3201
We utilise multi-epoch MUSE spectroscopy to study binary stars in the core of the Galactic globular cluster NGC 3201. Our sample consists of 3553 stars with 54 883 spectra in total comprising 3200…
A Method to Search for Black Hole Candidates with Giant Companions by LAMOST
We propose a method to search for stellar-mass black hole (BH) candidates with giant companions from spectroscopic observations. Based on the stellar spectra of LAMOST Data Release 6, we obtain a…
Discovery of an old nova remnant in the Galactic globular cluster M 22
A nova is a cataclysmic event on the surface of a white dwarf in a binary system that increases the overall brightness by several orders of magnitude. Although binary systems with a white dwarf are…
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 in…
How black holes shape globular clusters: Modeling NGC 3201
Numerical simulations have shown that black holes (BHs) can strongly influence the evolution and present-day observational properties of globular clusters (GCs). Using a Monte Carlo code, we…
On the black hole content and initial mass function of 47 Tuc
The globular cluster (GC) 47 Tuc has recently been proposed to host an intermediate-mass black hole (IMBH) or a population of stellar mass black holes (BHs). To shed light on its dark content, we…
No Black Holes in NGC 6397
Recently, Vitral & Mamon detected a central concentration of dark objects in the core-collapsed globular cluster NGC 6397, which could be interpreted as a subcluster of stellar-mass black holes.…
The dynamics of the globular cluster NGC 3201 out to the Jacobi radius
As part of a chemo-dynamical survey of five nearby globular clusters with 2dF/AAOmega on the Anglo-Australian Telescope (AAT), we have obtained kinematic information for the globular cluster NGC…
Stellar-mass Black Holes in Globular Clusters: Dynamical consequences and observational signatures
Abstract Sizeable number of stellar-mass black holes (BHs) in globular clusters (GCs) can strongly influence the dynamical evolution and observational properties of their host cluster. Using results…
Tidal Disruptions of Stars by Black Hole Remnants in Dense Star Clusters
In a dense stellar environment, such as the core of a globular cluster (GC), dynamical interactions with black holes (BHs) are expected to lead to a variety of astrophysical transients. Here we…

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 that…
Two stellar-mass black holes in the globular cluster M22
TLDR
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.
A black hole in a globular cluster
TLDR
The X-ray signature of an accreting black hole in a globular cluster associated with the giant elliptical galaxy NGC 4472 (in the Virgo cluster) is reported, which rules out any object other than a black Hole in such an old stellar population.
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 we…
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 cluster…
Could Black Hole X-Ray Binaries Be Detected in Globular Clusters?
TLDR
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.
The ACS survey of Galactic globular clusters
Context. The fraction of binary stars is an important ingredient to interpret globular cluster dynamical evolution and their stellar population. Aims. We investigate the properties of main-sequence…
BINARIES IN GLOBULAR-CLUSTERS
Binary stars in a globular cluster (hereafter, GC) may be primordial (i.e. formed along with the cluster), or the result of cluster dynamics. “Dynamical” binaries can result from conservative…
The central dynamics of M3, M13, and M92: stringent limits on the masses of intermediate-mass black holes
We used the PMAS integral field spectrograph to obtain large sets of radial velocities in the central regions of three northern Galactic globular clusters: M3, M13, and M92. By applying the novel…
