NED Abstract

Copyright by Royal Astronomical Society. 1995MNRAS.273..913C Morphological segregation of early-type galaxies in the Virgo cluster N. Caon and M. Einasto International School for Advanced Studies, via Beirut 2,34014 Trieste, Italy Tartu Astrophysical Observatory, EE2444 Toravere, Estonia Accepted 1994 November 1 Received 1994 October 3; in original form 1992 August 28 ABSTRACT We present evidence for a morphological segregation of early-type galaxies with different isophote shapes in the Virgo cluster. Comparing local projected densities around galaxies, we find that, independently of their classification as elliptical or lenticular, galaxies with boxy isophotes are located in local density enhancements, while galaxies with discy isophotes lie in regions of lower local densities. This segregation is therefore not just the reflection of ordinary morphological segregation between elliptical and lenticular galaxies, and it shows that the property of galaxies that is more sensitive to the environment is the presence or not of a stellar disc, rather than the bulge-to-disc ratio (and therefore the classification as an E or an S0 galaxy). Key words: galaxies: clusters: general - galaxies: clusters: individual: Virgo - galaxies: elliptical and lenticular, cD.
