Star-forming regions in the intragroup medium of compact groups of galaxies
S. Torres-Flores, C. Mendes de Oliveira, D. F. de Mello +4
We present the results of a multiwavelength campaign searching for young objects in the intragroup medium of seven compact groups of galaxies: HCG 2, 7, 22, 23, 92, 100 and NGC 92.…
Revisiting the fossil group candidates UGC 842 and NGC 6034
Raimundo Lopes de Oliveira, Eleazar Rodrigo Carrasco, Claudia Mendes de Oliveira +4
We present a new insight on NGC 6034 and UGC 842, two groups of galaxies previously reported in the literature as being fossil groups. The study is based on optical photometry and…
The star formation histories of fossil group galaxies
I. G. de la Rosa, R. N. Proctor, C. Mendes de Oliveira +3
A comparison is carried out among the star formation histories of early-type galaxies (ETG) in fossil groups, clusters and low density environments. Although they show similar evol…
Mass Distribution in Hickson Compact Groups of Galaxies
H. Plana, P. Amram, C. Mendes de Oliveira +1
This study presents the mass distribution for a sample of 18 late-type galaxies in nine Hickson Compact Groups. We used rotation curves from high resolution 2D velocity fields of F…
Star formation in the intragroup medium and other diagnostics of the evolutionary stages of compact groups of galaxies
S. Torres-Flores, C. Mendes de Oliveira, D. F. de Mello +4
Context: Compact groups of galaxies are entities that have high densities of galaxies and serve as laboratories to study galaxy interactions, intergalactic star formation and galax…
An analysis of the composite stellar population in M32
P. Coelho, C. Mendes de Oliveira, R. Cid Fernandes
We obtained long-slit spectra of high signal-to-noise ratio of the galaxy M32 with the GMOS spectrograph at the GEMINI North telescope. We analysed the integrated spectra by means…
