Testing Bose-Einstein Condensate dark matter models with the SPARC
  galactic rotation curves data
  The nature of one of the fundamental components of the Universe, the dark
matter, is still unknown. One interesting possibility is that dark matter could
exist in the form of a self-interacting Bose-Einstein Condensate (BEC). The
fundamental properties of the dark matter in this model are determined by two
parameters only, the mass and the scattering length of the particle. In the
present study we investigate the properties of the galactic rotation curves in
the BEC dark matter model, with quadratic self-interaction, by using 173
galaxies from the recently published Spitzer Photomery \& Accurate Rotation
Curves (SPARC) data. We fit the theoretical predictions of the rotation curves
in the slowly rotating BEC models with the SPARC data by using genetic
algorithms. We provide an extensive set of figures of the rotation curves, and
we obtain estimates of the relevant astrophysical parameters of the BEC dark
matter halos (central density, angular velocity and static radius). The density
profiles of the dark matter distribution are also obtained. It turns out that
the BEC model gives a good description of the SPARC data. The presence of the
condensate dark matter could also provide a solution for the core/cusp problem.
