The compact group--fossil group connection: observations of a massive compact group at z=0.22
Claudia L. Mendes de Oliveira, Eleazar R. Carrasco
It has been suggested that fossil groups could be the cannibalized remains of compact groups, that lost energy through tidal friction. However, in the nearby universe, compact grou…
Fossil Groups in the Sloan Digital Sky Survey
Walter A. Santos, Claudia Mendes de Oliveira, Laerte Sodré
A search for fossil groups in the Sloan Digital Sky Survey was performed using virtual observatory tools. A cross-match of the positions of all SDSS Luminous Red Galaxies (with r <…
The Dwarf Galaxy Population in Nearby Groups. The data
Eleazar R. Carrasco, Claudia M. de Oliveira, Leopoldo Infante
We used V and I CCD photometry to search for low-surface brightness dwarf galaxies (LSBD) in the central (<0.5 h^-1 Mpc) region of the groups NGC 6868, NGC 5846, HCG 42 and the poo…
Velocity dispersion, mass and the luminosity function of the fossil cluster RX J1416.4+2315
Eduardo S. Cypriano, Claudia L. Mendes de Oliveira, Laerte Sodré
We study the properties of the fossil cluster RX J1416.4+2315 through g' and i'-band imaging and spectroscopy of 25 member galaxies. The system is at a mean redshift of 0.137 and h…
The K luminosity-metallicity relation for dwarf galaxies and the tidal dwarf galaxies in the tails of HCG 31
Claudia L. Mendes de Oliveira, Sonia Temporin, Eduardo S. Cypriano +4
We determine a K-band luminosity-metallicity (K-Z) relation for dwarf irregular galaxies, over a large range of magnitudes, -20.5 < M_K < -13.5, using a combination of K photometry…
Ages, metallicities and -element enhancement for galaxies in Hickson compact groups
C. Mendes de Oliveira, P. Coelho, J. J. González +1
Central velocity dispersions and eight line-strength Lick indices have been determined from 1.3 resolution long-slit spectra of 16 elliptical galaxies in Hickson compact g…
