Evaporation of Primordial Black Holes in a Thermal Universe: A Thermofield Dynamics Approach
Ayan Chatterjee, Jitumani Kalita, Debaprasad Maity
We investigate the impact of a finite temperature environment on the Hawking radiation from black holes (BHs), with particular focus on Kerr BHs immersed in a cosmological thermal…

Black holes in thermal bath live shorter: implications for primordial black holes
Jitumani Kalita, Debaprasad Maity, Ayan Chatterjee
Hawking radiation from a non-extremal black hole is known to be approximately Planckian. The thermal spectrum receives multiple corrections including greybody factors and due to ki…
