Spectra of Cluster Galaxies at z~0.4
Abstract
The ``MORPHS'' group has obtained an extensive spectroscopic dataset of galaxies in the fields of 10 rich clusters at ; the stellar population properties of about 700 objects have been determined from a detailed analysis of spectral line strenghts and colours, up to a galactic absolute magnitude mag. Morphological informations for a consistent fraction of our sample have been previously derived from deep images of the central regions of these clusters taken with the WFPC-2 on board the HST. Spectral and morphological features can be compared in order to study the star formation histories of the different galactic types in clusters; here we show some preliminary results of this comparison.
