Dwarf Galaxies in the Antlia Cluster: First Results
Abstract
The Antlia cluster (l = 273°, b = 19°) is the third nearest galaxy cluster (d = 35 Mpc) after Virgo and Fornax. In spite of its proximity, it has been poorly investigated. Its population is dominated by early type galaxies, with dwarf ellipticals being the most abundant galaxy type [1].
Here we present the first results of a project aimed to study the galaxy population of the Antlia cluster. Our results correspond to the identification and classification of dwarf galaxies in the central cluster region, extending the list of \cite{FS90} (FS90 catalogue), a photographic survey that is complete only up to B_T ≃ 18 mag (M_B ≃ -14.7 mag at the Antlia cluster distance). The final aim of our project is to study the luminosity function, morphology and structural parameters of dwarf galaxies in the Antlia cluster with a more complete sample. We also intend to investigate the kinematics of the cluster (50 spectra have been already obtained).- Publication:
