Constraints on the mass and self-coupling of Ultra-Light Scalar Field Dark Matter using observational limits on galactic central mass

Sayan Chakrabarti, Bihag Dave, Koushik Dutta +1

It is well known that Ultra-Light Dark Matter (ULDM), usually scalar fields of mass $m\sim 10^{-22}\mathrm{eV}$, can solve some of the outstanding problems of the Cold Dark Matter (…
