Dwarf galaxies in multistate Scalar Field Dark Matter haloes
  We analyse the velocity dispersion for eight of the Milky Way dwarf
spheroidal satellites in the context of finite temperature scalar field dark
mater. In this model the finite temperature allows the scalar field to be in
configurations that possess excited states, a feature that has proved to be
necessary in order to explain the asymptotic rotational velocities found in low
surface brightness (LSB) galaxies. In this work we show that excited states are
not only important in large galaxies but also have visible effects in dwarf
spheroidals. Additionally, we stress that contrary to previous works where the
scalar field dark matter haloes are consider to be purely Bose-Einstein
condensates, the inclusion of excited states in these halo configurations
provides a consistent framework capable of describing LSBs and dwarf galaxies
of different sizes without arriving to contradictions within the scalar field
dark matter model. Using this new framework we find that the addition of
excited states accounts very well for the raise in the velocity dispersion in
Milky Way dwarf spheroidal galaxies improving the fit compared to the one
obtained assuming all the DM to be in the form of a Bose Einstein Condensate.
