Dwarf Galaxy Constraints on Interacting Fermionic Dark Matter
Bihag Dave, Raghuveer Garani
Dwarf galaxies in the Local Group offer a way to test dark matter (DM) models against stellar kinematic data. In this work, we study degenerate fermionic DM in two cases: the stand…
Self-Gravitating Scalar Field Configurations, Ultra Light Dark Matter and Galactic Scale Observations
Bihag Dave
In this thesis, we investigate the possibility that dark matter consists of ultra light spin-zero particles with mass . We focus on the role of self-int…
Learning from galactic rotation curves: a neural network approach
Bihag Dave, Gaurav Goswami
For a galaxy, given its observed rotation curve, can one directly infer parameters of the dark matter density profile (such as dark matter particle mass , scaling parameter ,…
ULDM self-interactions, tidal effects and tunnelling out of satellite galaxies
Bihag Dave, Gaurav Goswami
It is well-known that Dark Matter (DM) inside a satellite galaxy orbiting a host halo experiences a tidal potential. If DM is ultra-light, given its wave-like nature, one expects i…
