In this paper the problem of the phenomenological modelling of
elliptical galaxies using various available observational data is presented. Recently,
Tortora, Cardona and Piedipalumbo (2007) suggest...

2010/10/19
We propose a new analytic approximation for the luminosity function of galaxies. The suggested expression behaves like the Schechter function at the faint end (φ ∼ Lα) but departs considerably a...
