The search for extratidal star candidates around Galactic globular clusters NGC 2808, NGC 6266, and NGC 6397 with Gaia DR2 astrometry
(EDP Sciences, 2021-01)
Abstract
Context. Extratidal stars are stellar bodies that end up outside the tidal radius of a cluster as a result of internal processes or external forces acting upon it. The presence and spatial distribution of these ...
Homogeneous metallicities and radial velocities for Galactic globular clusters
(EDP SCIENCES S ALES ULIS CEDEX A, 2012)
Well determined radial velocities and abundances are essential for analyzing the properties of the globular cluster system of the Milky Way. However more than 50% of these clusters have no spectroscopic measure of their ...
New VVV Survey Globular Cluster Candidates in the Milky Way Bulge
(2017)
It is likely that a number of Galactic globular clusters remain to be discovered, especially toward the Galactic bulge. High stellar density combined with high and differential interstellar reddening are the two major ...
Stellar clusters multicolor photometry at OAUNI
(Universidad Nacional de Ingeniería, 2019-06-06)
In this work we present preliminary analysis of the astronomical photometry program for stellar clusters observed at OAUNI on the last years. Up to date twelve open clusters and nine globular clusters have been observed, ...
Specific Frequencies and Luminosity Profiles of Cluster Galaxies and Intracluster Light in Abell 1689
(IOP PUBLISHING LTD, 2017)
We present magnitudes and profile fits for 180 galaxies in the central field of the massive lensing cluster Abell 1689 using very deep imaging with the Hubble Space Telescope Advanced Camera for Surveys in the F814W bandpass. ...
Discovery of VVV CL001 A low-mass globular cluster next to UKS 1 in the direction of the Galactic bulge
(EDP SCIENCES S A, 2011)
Context. It is not known how many globular clusters may remain undetected towards the Galactic bulge.
Intra-cluster Globular Clusters in a Simulated Galaxy Cluster
(IOP Publishing, 2018-01)
Using a cosmological dark matter simulation of a galaxy-cluster halo, we follow the temporal evolution of its globular cluster population. To mimic the red and blue globular cluster populations, we select at high redshift ...
