Globular cluster formation in the context of galaxy formation and evolution [PDF]
, 2014 The formation of globular clusters (GCs) remains one of the main unsolved problems in star and galaxy formation. The past decades have seen important progress in constraining the physics of GC formation from a variety of directions.

Near-Infrared Photometry of Metal Rich Globular Cluster M71 [PDF]
Journal of Astronomy and Space Sciences, 1997 We have carried out JK near-infrared photometry for the central region of the metal rich globular cluster M71, whose(K, J - K) color-magnitude diagram is presented here. Using two independent methods we derive the distance modulus to M71, 12.89 and 12.86

Internal Kinematics and Structure of the Bulge Globular Cluster NGC 6569
The Astrophysical Journal, 2023 In the context of a project aimed at characterizing the properties of star clusters in the Galactic bulge, here we present the determination of the internal kinematics and structure of the massive globular cluster NGC 6569.

A CATALOG OF GLOBULAR CLUSTER SYSTEMS: WHAT DETERMINES THE SIZE OF A GALAXY'S GLOBULAR CLUSTER POPULATION? [PDF]
, 2013 We present a catalog of 422 galaxies with published measurements of their globular cluster (GC) populations. Of these, 248 are E galaxies, 93 are S0 galaxies, and 81 are spirals or irregulars.

Keck Imaging of the Globular Cluster Systems in the Early--type Galaxies NGC 1052 and NGC 7332
, 2001 The presence of two globular cluster subpopulations in early-type galaxies is now the norm rather than the exception. Here we present two more examples for which the host galaxy appears to have undergone a recent merger.

Compact Binaries in Globular Clusters [PDF]
International Astronomical Union Colloquium, 2004 AbstractIn dense stellar systems the frequent dynamical interactions between stars play a crucial role in the formation and evolution of compact binaries. We study these processes using a novel approach combining a state-of-the- art binary population synthesis code with a simple treatment of dynamical interactions in dense star cluster cores.

RR Lyrae Stars Belonging to the Candidate Globular Cluster Patchick 99
The Astrophysical Journal LettersPatchick 99 is a candidate globular cluster located in the direction of the Galactic bulge, with a proper motion almost identical to the field and extreme field star contamination. A recent analysis suggests it is a low-luminosity globular cluster with a

The Extended Baryonic Halo of NGC 3923
Galaxies, 2017 Galaxy halos and their globular cluster systems build up over time by the accretion of small satellites. We can learn about this process in detail by observing systems with ongoing accretion events and comparing the data with simulations.

The Spectacular Tidal Tails of Globular Cluster M3 (NGC 5272)
The Astrophysical Journal, 2023 We provide a detailed analysis of the tidal tails of the globular cluster M3 (NGC 5272). We first discover clear extratidal structures with a slight S shape near the cluster. This inspires us to examine the existence of its long tidal tails. We highlight
