摘要：We derive the Baryonic Mass Function of galactic structures from their inner kinematics and
prove its cosmological importance by showing its universal nature, its substantial independency
of the method with which is derived. The present day amount of baryons estimated from the BMF
is in good agreement with that obtained by integrating the star formation occurred in the Universe
over the whole Hubble time.
From the BMF and the theoretical Halos Mass Function of virialized objects, we obtain the relationship
between the baryonic mass of a galaxy and its virial (total, dark) mass. We find that
this relation clearly bears the effect of baryonic feedbacks occurred during the galaxy formation
process, i.e. the supernovae explosions and the quasar activity, that have coupled the dark and
ordinary matter in galaxies.
