Semi-Analytic Modelling of Galaxy Formation : The Local Universe

  title={Semi-Analytic Modelling of Galaxy Formation : The Local Universe},
  author={Rachel S. Somerville and Joel R. Primack},
Using semi-analytic models (SAMs), we investigate galaxy properties such as the TullyFisher relation, the B-band luminosity function, cold gas contents, sizes, metallicities, and colours, and compare our results with observations of local galaxies. We consider several different recipes for star formation and supernova feedback, including choices that are similar to the treatment in Kauffmann, White & Guiderdoni (1993) and Cole et al. (1994) as well as some new recipes. In our fiducial models… CONTINUE READING
