Descripción
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-disco ratio (and therefore the classification as an E or an S0
galaxy).
