Seyfert's Sextet: A Slowly Dissolving Stephan's Quintet?
A. Durbala, A. del Olmo, M. S. Yun +7
We present a multiwavelength study of the highly evolved compact galaxy group known as Seyfert's Sextet (HCG79: SS). We interpret SS as a 2-3 Gyr more evolved analog of Stephan's Q…
From Nearby to High Redshift Compact Group of Galaxies
Philippe Amram, Chantal Balkowski, Claudia Mendes de Oliveira +2
Nearby Compact Groups of Galaxies (CGs) are very complex systems, tracing their history is a challenge (e.g. Stephan's Quintet). The presence of a diffuse X-rays emission that ofte…
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…
GMOS-IFU Spectroscopy of 167-317 (LV2) Proplyd in Orion
M. J. Vasconcelos, A. H. Cerqueira, H. Plana +2
We present high spatial resolution spectroscopic observations of the proplyd 167-317 (LV2) near the Trapezium cluster in the Orion nebula, obtained during the System Verification r…
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…
Dynamical effects of interactions and the Tully-Fisher relation for Hickson compact groups
C. Mendes de Oliveira, P. Amram, H. Plana +1
We investigate the properties of the B-band Tully-Fisher (T-F) relation for 25 compact group galaxies, using Vmax derived from 2-D velocity maps. Our main result is that the majori…
