Morphological Differences in the Nature of Radio Sources in High Density Groups

Abstract

A VLA study of 393 galaxies in high density groups has shown that the absolute magnitude distributions of radio-loud and radio-quiet ellipticals in the groups are the same while the radio-loud spirals are significantly brighter than the radio-quiet spirals. Furthermore radio sources in ellipticals are found only among the brightest ellipticals in a group independent of their optical luminosity. These results suggest a fundamental difference in the ultimate consequences of interaction for ellipticals and spirals in a group and the subsequent triggering of nuclear activity.
