Abstract:Low-luminosity galaxies are known to outnumber the bright galaxy population in poor groups and clusters of galaxies. Yet, the investigation of low-luminosity galaxy populations outside the Local Group remains rare and the dependence on different group environments is still poorly understood. Previous investigations have uncovered the photometric scaling relations of early-type dwarfs and a strong dependence of morphology with environment. The present study aims to analyse the photometric and spectroscopic properties of the low-luminosity galaxy population in the nearby, well-evolved and early-type dominated NGC 5846 group of galaxies.

Abstract: (hide)
Spectroscopically selected low-luminosity group members from the Sloan Digital Sky Survey with cz<3000km/s within a radius of 2{deg}=0.91Mpc around NGC 5846 are analysed. Surface brightness profiles of early-type galaxies are fit by a Sersic model {propto}r^1/n^. Star formation rates, oxygen abundances, and emission characteristics are determined for emission-line galaxies.
