Chemical abundances of giant stars in the Crater stellar system
(EDP SCIENCES S A, 2015)
Aims. We obtained spectra for two giants of Crater (Crater J113613-105227 and Crater J113615-105244) using X-Shooter at the VLT, with the purpose of determining their radial velocities and metallicities.
Chemical abundance analysis of red giant branch stars in the globular cluster E3
(2018)
Context. Globular clusters are known to host multiple stellar populations, which are a signature of their formation process. The globular cluster E3 is one of the few low-mass globulars that is thought not to host multiple ...
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. ...
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 ...
Chemical abundances of giant stars in NGC 5053 and NGC 5634, two globular clusters associated with the Sagittarius dwarf spheroidal galaxy?
(EDP SCIENCES S A, 2015)
Context. The tidal disruption of the Sagittarius dwarf spheroidal galaxy (Sgr dSph) is producing the most prominent substructure in the Milky Way (MW) halo, the Sagittarius Stream. Aside from field stars, it is suspected ...
