J-PAS: forecasts on interacting vacuum energy models
V. Salzano, C. Pigozzo, M. Benetti +21
The next generation of galaxy surveys will allow us to test some fundamental aspects of the standard cosmological model, including the assumption of a minimal coupling between the…
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 <…
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…
Shrinking of Cluster Ellipticals: a Tidal Stripping explanation and Implications for the Intra-Cluster Light
Eduardo S. Cypriano, Laerte Sodré, Luis E. Campusano +2
We look for evidence of tidal stripping in elliptical galaxies through the analysis of homogeneous CCD data corresponding to a sample of 228 elliptical galaxies belonging to 24 clu…
The Compact Group of Galaxies HCG 31 is in an early phase of merging
P. Amram, C. Mendes de Oliveira, H. Plana +1
We have obtained high spectral resolution (R = 45900) Fabry-Perot velocity maps of the Hickson Compact Group HCG 31 in order to revisit the important problem of the merger nature o…
