Tales within Tales and Cutoffs within Cutoffs: What Sets the Mass Scale for Galaxies?
arXiv:astro-ph/0112554 · doi:10.1007/10856495_1
Abstract
Please answer ``yes'' or ``no'': 1. Does the mass function for clusters of galaxies cut off exponentially? 2. Does the luminosity function for galaxies cut off exponentially? 3. Is the dependence of virial velocity on galaxy luminosity a power law? 4. Does the velocity function for galaxies cut off exponentially?
