Pfleiderer2: identification of a new globular cluster in the Galaxy
, 2009 We provide evidence that indicate the star cluster Pfleiderer 2, which is projected in a rich field, as a newly identified Galactic globular cluster. Since it is located in a crowded field, core extraction and decontamination tools were applied to reveal

Surviving Tidal Tails Around the Milky Way Bulge Globular Cluster NGC 6355
The Astronomical JournalWe present results of the analysis of a set of images obtained in the field of the Milky Way bulge globular cluster NGC 6355 using the Dark Energy Camera, which is attached to the 4 m Blanco telescope of the Cerro-Tololo Interamerican Observatory.

The Luminosity Distribution of Globular Clusters in Dwarf Galaxies
, 2007 The majority of the globular clusters associated with the Sagittarius dwarf galaxy are faint. In this respect it differs significantly from the globular cluster systems surrounding typical giant galaxies. The observation that most of globular clusters in

The strange hot horizontal-branch binary star in NGC 6752
Open Astronomy, 2018 M5865 is the only so-far confirmed close binary found in the extreme horizontal branch (EHB) of a globular cluster. A detailed study has recently proposed that this object could be a close system (period P=1.61 days) comprising a EHB and a main-sequence ...

The Radial Velocities of Globular Clusters [PDF]
Proceedings of the National Academy of Sciences, 1930 The following discussion of the radial velocities of globular clusters originated in conversations which I had with Dr. Zwicky of the California Institute of Technology during my stay at the Mount Wilson Observatory. Since it depends essentially on the validity of Stromberg's solution for the motion of the sun relative to the system of the globular ...

Globular cluster clustering in M31
The Astronomical Journal, 1993 We present an analysis of the positions and velocities of M31 globular clusters, which indicates the presence of significant substructure in the globular cluster system. We suggest this clustering is the surviving signature of gaseous clumps out of which the halo of M31 formed.

Improved Particle Spray Algorithm for Modeling Globular Cluster Streams
The Astrophysical Journal Supplement SeriesStellar streams that emerge from globular clusters (GCs) are thin stellar structures spread along the orbits of progenitor clusters. Numerical modeling of these streams is essential for understanding their interaction with the host galaxy's mass ...
