Description
The nature of dark matter (DM) is one of the most relevant questions
in modern astrophysics. I will present
a brief overview of recent results that inquire into a possible
fermionic quantum nature of the DM particles,
focusing mainly on the interconnection between the microphysics of the
neutral fermions and the macro-
physical structure of galactic halos. I will show how such an
interconnection when analyzed through a first
principle physics model based on statistical mechanics and
thermodynamics of self-gravitating fermions, leads
to a richer core-halo structure for the DM halos than the one obtained
from N-body simulations. I will dis-
cuss the many distinct applications of such a fermionic model both on
halo scales -including morphology
constraints from rotation curves and stellar streams- all the way to
galaxy center scales -including the case
of SgrA* and supermassive BH formation-. In particular I will
highlight the possibility that the Milky way, as well as low luminosity
AGNs, harbor a dense DM fermion-core at their centers instead of a
supermassive black hole.
