A Universal SFDM Halo Mass for the Andromeda and Milky Way's dSphs?
  Dwarf spheroidal galaxies are the most common type of galaxies, and are the
most dark matter dominated objects in the Universe. Therefore, they are ideal
laboratories to test any dark matter model. The Bose-Einstein condensate/scalar
field dark matter model considers that the dark matter is composed by
spinless-ultra-light particles which can be described by a scalar field. This
model is an alternative to the $\Lambda$-cold dark matter model. In this work I
study the kinematics of the dwarf spheroidal satellite galaxies of the Milky
Way and Andromeda, under the scalar field/BEC dark matter paradigm in two
limits: when the self interacting parameter is equal to zero, and when the self
interacting parameter is $\gg1$. I find that dwarf spheroidal galaxies with
very high mass-to-light ratios (higher than $100$) are in better agreement with
an NFW mass density profile. On the other hand, dwarf spheroidal galaxies with
relatively low mass-to-light ratios and high luminosities are better described
with the SFDM model. Such results are very encouraging to further test
alternative dark matter models using the dynamics of dwarf galaxies as a tool.
