Gravitational Radiation from Black Hole Binaries in Globular Clusters [PDF]
, 2001 A populations of stellar mass black hole binaries may exist in globular clusters. The dynamics of globular cluster evolution imply that there may be at most one black hole binary is a globular cluster.

The devil is in the tails: the role of globular cluster mass evolution on stream properties [PDF]
, 2017 We present a study of the effects of collisional dynamics on the formation and detectability of cold tidal streams. A semi-analytical model for the evolution of the stellar mass function was implemented and coupled to a fast stellar stream simulation ...

Dynamical Friction in dE Globular Cluster Systems [PDF]
, 2001 The dynamical friction timescale for globular clusters to sink to the center of a dwarf elliptical galaxy (dE) is significantly less than a Hubble time if the halos have King-model or isothermal profiles and the globular clusters formed with the same ...

MUSE crowded field 3D spectroscopy of over 12 000 stars in the globular cluster NGC 6397 - I. The first comprehensive HRD of a globular cluster [PDF]
, 2016 Aims. We demonstrate the high multiplex advantage of crowded field 3D spectroscopy with the new integral field spectrograph MUSE by means of a spectroscopic analysis of more than 12 000 individual stars in the globular cluster NGC 6397. Methods.

The Dependence of Globular Cluster Number on Density for Abell Cluster Central Galaxies [PDF]
, 1997 A study of the globular cluster systems of 23 brightest, or central, galaxies in 19 Abell clusters has recently been completed. This Letter presents some of the newly discovered correlations of the globular cluster specific frequency $S_N$ in these ...

THE ABUNDANCES IN THE STELLAR ATMOSPHERES IN THE M13 GLOBULAR CLUSTER
Odessa Astronomical Publications, 2017 The chemical composition of 5 stars' atmospheres in globular cluster M13 and 2 halo stars taken from literature have been computed. A slight excess of O and deficit of Mg have been defined for globular cluster stars.

The dragon simulations: globular cluster evolution with a million stars [PDF]
, 2016 Introducing the dragon simulation project, we present direct N-body simulations of four massive globular clusters (GCs) with 106 stars and 5 per cent primordial binaries at a high level of accuracy and realism.

GLOBULAR CLUSTER STREAMS AS GALACTIC HIGH-PRECISION SCALES—THE POSTER CHILD PALOMAR 5 [PDF]
Proceedings of the International Astronomical Union, 2015 Using the example of the tidal stream of the Milky Way globular cluster Palomar 5 (Pal 5), we demonstrate how observational data on tidal streams can be efficiently reduced in dimensionality and modeled in a Bayesian framework.

The youngest globular clusters [PDF]
International Journal of Modern Physics D, 2014 It is likely that all stars are born in clusters, but most clusters are not bound and disperse. None of the many protoclusters in our Galaxy are likely to develop into long-lived bound clusters. The super star clusters (SSCs) seen in starburst galaxies are more massive and compact and have better chances of survival. The birth and early development of

Diffusion and Mixing in Globular Clusters [PDF]
The Astrophysical Journal, 2018 Abstract Collisional relaxation describes the stochastic process with which a self-gravitating system near equilibrium evolves in phase-space due to the fluctuating gravitational field of the system. The characteristic timescale of this process is called the relaxation time. In this paper, we highlight the difference between two measures
