Query: Cosmology with the Space-Luminosity Distribution of Virialized Halos   We derive the observed luminosity function of virialized systems. Coupling
this statistic with the mass function predicted by CDM cosmogonies we obtain
the functional behavior of the mass-to-light ratio over a wide dyna mical range
in mass. We conclude that the mass-to-light ratio has a minimum close t o the
luminosity of an L* galaxy halo. We also show how to derive in a
self-consistent way the X-ray-to-optical luminosity ratio for galaxy systems.
As a consequence, we predict a fundamental break in the auto-similar scaling
behavior of fundamental correlat ions in going from the group to the cluster
scales.
