NED Abstract

Copyright by Royal Astronomical Society. 2010MNRAS.409.1455H The stellar populations of early-type galaxies - I. Observations, line strengths and stellar population parameters Harrison, Craig D.; Colless, Matthew; Kuntschner, Harald; Couch, Warrick J.; de Propris, Roberto; Pracy, Michael B. Abstract. The influence of environment on the formation and evolution of early-type galaxies is, as yet, an unresolved issue. Constraints can be placed on models of early-type galaxy formation and evolution by examining their stellar populations as a function of environment. We present a catalogue of galaxies well suited to such an investigation. The magnitude-limited (?) sample was drawn from four clusters (Coma, A1139, A3558 and A930 at <z>= 0.04) and their surrounds. The catalogue contains luminosities, redshifts, velocity dispersions and Lick line strengths for 416 galaxies, of which 245 are classified as early types. Luminosity-weighted ages, metallicities and {alpha}-element abundance ratios have been estimated for 219 of these early types. We also outline the steps necessary for measuring fully calibrated Lick indices and estimating the associated stellar population parameters using up-to-date methods and stellar population models. In a subsequent paper we perform a detailed study of the stellar populations of early-type galaxies in clusters and investigate the effects of environment. Key words: methods: data analysis, galaxies: clusters: general, galaxies: elliptical and lenticular, cD, galaxies: stellar content
