Rotation curves of rotating galactic BEC dark matter halos
read the original abstract
We present the dynamics of rotating Bose Condensate galactic dark matter halos, made of an ultralight spinless boson. We restrict to the case of adding axisymmetric rigid rotation to initially spherically symmetric structures and show there are three regimes: i) small angular momentum, that basically retains the drawbacks of spherically symmetric halos related to compactness and failure at explaining galactic RCs, ii) an intermediate range of values of angular momentum that allow the existence of long-lived structures with acceptable RC profiles, and iii) high angular momentum, in which the structure is dispersed away by rotation. We also present in detail the new code used to solve the Gross-Pitaevskii Poisson system of equations in three dimensions.

Testing Scalar Field Dark Matter models in M31 galaxy through the Rotation Curve analysis
Fuzzy dark matter with smooth cored halos provides the most consistent description of M31's rotation curve among scalar field models when paired with a two-bulge baryonic configuration.
