Updated census of RR Lyrae stars in the globular cluster ω Centauri (NGC 5139)
(EDP Sciences, 2015-05)
Aims. ω Centauri (NGC 5139) contains many variable stars of different types and, in particular, more than one hundred RR Lyrae stars. This enabled gathering a homogeneous sample (in terms of instrument, image quality, and ...
Tidal stripping of globular clusters in a simulated galaxy cluster
(IOP Publishing, 2015-06)
Using a cosmological N-body numerical simulation of the formation of a galaxy-cluster-sized halo, we analyze the temporal evolution of its globular cluster population. We follow the dynamical evolution of 38 galactic dark ...

G2C2-IV.A novel approach to study the radial distributions of multiple populations in Galactic globular clusters
(OXFORD UNIV PRESS, 2015)
We use the horizontal branch (HB) morphology of 48 Galactic globular clusters (GCs) to study the radial distributions of the different stellar populations known to exist in GCs. Assuming that the (extremely) blue HB stars ...
Curiuos Variables Experiment (CURVE): Variable Stars in the Metal-Poor Globular Cluster M56
(2008)
We have surveyed a 6.5' x 6.5' field centered on the globular cluster M56 (NGC 6779) in search for variable stars. We have detected seven variables, among which two objects are new identifications. One of the new variables ...
Searching for a predicted metallicity variation in the type II globular cluster NGC 362 = Buscando una variación de metalicidad predicha en el cúmulo globular de tipo II NGC 362.
(Universidad de Concepción.Facultad de Ciencias Físicas y MatemáticasDepartamento de Astronomía., 2021)
According to Milone et al. (2017), NGC 362 is a rare Type II Galactic globular cluster,
showing a complex pseudo two-color diagram or ’Chromosome Map’ based on their
HST UV Legacy photometry. The clear separation of its ...
Large-scale study of the NGC 1399 globular cluster system in Fornax
(EDP Sciences, 2006-06)
We present a Washington C and Kron-Cousins R photometric study of the globular cluster system of NGC 1399, the central galaxy of the Fornax cluster. A large areal coverage of 1 square degree around NGC 1399 is achieved ...
