We analyse Spitzer MIPS 24� m observations, and Sloan Digital Sky Survey (DR7) optical broadband photometry and spectra, to investigate the star formation properties of galaxies residing in the Coma supercluster region. We find that star fo rmation (SF) in dwarf galaxies is quenched only in the high density environment at the centre of clusters and groups, but that passively-evolving massive galaxies are found in all environments, indicating that massive galaxies can become passive via internal… CONTINUE READING
