22 Jul 1999 | | Subject: | astro-ph | | Affiliation: | U. Innsbruck), F. Kerber (ESO, Garching | | Abstract: | We present the discovery of an isolated compact group of galaxies that is extremely dense (median projected galaxy separation: 6.9 kpc), has a very low velocity dispersion ($sigma_{
m 2D}$ = 67 km s$^{-1}$), and where all observed members show emission lines and are morphologically disturbed. These properties, together with the lack of spirals and the presence of a prominent tidal tail make this group one of the most evolved compact groups. | | Source: | arXiv, astro-ph/9907304 | | Services: | Forum | Review | PDF | Favorites | |
