Abstract:
Studies of dwarf spheroidal (dSph) galaxies with statistically
significant sample sizes are still rare beyond the Local Group, since
these low surface brightness objects can only be identified with deep
imaging data. In galaxy clusters, where they constitute the dominant
population in terms of number, they represent the faint end slope of
the galaxy luminosity function and provide important insight on the
interplay between galaxy mass and environment. In this study we
investigate the optical photometric properties of early-type galaxies
(dwarf ellipticals (dEs) and dSphs) in the Virgo cluster core region,
by analysing their location on the colour magnitude relation (CMR) and
the structural scaling relations down to faint magnitudes, and by
constructing the luminosity function to compare it with theoretical
expectations.
Description:
Our work is based on deep CFHT V- and I-band data covering several
square degrees of the Virgo cluster core that were obtained in 1999
using the CFH12K instrument. We visually select potential cluster
members based on morphology and angular size, excluding spiral
galaxies. A photometric analysis has been carried out for 295
galaxies, using surface brightness profile shape and colour as further
criteria to identify probable background contaminants. 216 galaxies
are considered to be certain or probable Virgo cluster members.
