Relativistic Signatures of Dark Matter Equations of State in Static Spherically Symmetric Spacetimes
Akash Yadav, Sudhava Yadav, K. K. Venkataratnam
We study how three physically motivated dark matter equations of state alter the spacetime geometry of static, spherically symmetric black holes in General Relativity. The models c…

Reheating study of Mexican-Hat-type Potentials
Sudhava Yadav, Akash Yadav, K. K. Venkataratnam
We study reheating in Mexican Hat type potentials, emphasizing the role of the post-inflationary equation-of-state parameter() in shaping observable pred…
