Multi-component Dark Matter and Small Scale Structure Formation
Robert Wiley Deal, Kishan Sankharva, Kuver Sinha +1
We consider the evolution of non-thermal dark matter perturbations in models which contain both Weakly Interacting Massive Particles (WIMPs) and axions. Using constraints from exis…

Nonminimally coupled ultralight axions as cold dark matter
Kishan Sankharva, Shiv Sethi
We consider a nonminimally coupled scalar field as a potential cold dark matter candidate. These models are natural extensions of the ultralight axion models which are based on min…

Explaining Excess Dipole in NVSS Data Using Superhorizon Perturbation
Kaustav K. Das, Kishan Sankharva, Pankaj Jain
Many observations in recent times have shown evidence against the standard assumption of isotropy in the Big Bang model. Introducing a superhorizon scalar metric perturbation has b…
