A New Ultra-dense Group of Obscured Emission-Line Galaxies

Astrophysics 2009-10-31 v1

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 (σ2D\sigma_{\rm 2D} = 67 km s1^{-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.
