The Mass to Light ratio and the Initial Mass Function in galactic discs

arXiv:astro-ph/0210386 · doi:10.1023/A:1024060629820

Abstract

A low mass-to-light ratio for the baryonic component of spiral galaxies is advocated by a number of dynamical studies and by cosmological simulations of galaxy formation. We discuss the possibility of obtaining low mass-to-light ratios for the stellar component in discs, by changing the Initial Mass Function and the Star Formation History.
