Super star clusters and their multiple stellar populations
(Cambridge University Press, 2019)
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, ...
An Investigation of the Use of Synthetic Spectra to Find the Ages of Stellar Clusters
(IOP Publishing, 2013-11)
The utility of stellar cluster aging methods based on integrated spectra is clearly demonstrated by its extensive use by researchers for decades. However, few studies have determined the accuracy of such methods using a ...
The stellar kinematics of the giant halos ofBrightest Cluster Galaxies
(Diaferio, A., 2004)
We have investigated the stellar kinematics of two brightest cluster galaxies (BCGs) to large distances from the cluster centre. In both galaxies, the velocity dispersion rises with radius. Orbital anisotropy is ruled out ...
Distances from Stellar Kinematics for Peculiar Virgo Cluster Spiral Galaxies
(2008)
We present distance estimates for eleven peculiar Virgo cluster spiral galaxies based on measurements of the stellar kinematics of their central 2 kpc. Stellar circular velocities were obtained using two-integral dynamical ...

Análise de populações estelares e subestruturas em aglomerados de galáxias
(Universidade Federal de Santa MariaBRFísicaUFSMPrograma de Pós-Graduação em Física, 2015-08-25)
In this work, we investigated differences between stellar populations of galaxies that are part
of a cluster with and without substructures. We used optical spectra obtained from Sloan Digital
Sky Servey III DR10 for the ...
