Multistate scalar field dark matter and its correlation with galactic properties.

A. Hernandez-Almada, Miguel A. Garcia-Aspeitia

In this paper, we search for correlations between the intrinsic properties of galaxies and the Bose-Einstein condensate (BEC) under a scalar field dark matter (SFDM) at temperature of condensation greater than zero. According to this paradigm the BEC is distributed in several states. Based on the galactic rotation curves collected in SPARC dataset, we observe that SFDM parameters present a weak correlation with most of the galaxy properties, having only a correlation with those related to neutral hydrogen emissions. In addition, we found evidence to support of self-interaction between the different BEC states, proposing that in future studies must be considered crossed terms in SFDM equations. Finally, we find a null correlation with galaxy distances giving support to non-hierarchy of SFDM formation.
