Inflaton Accretion onto Primordial Black Holes During Reheating
Jitumani Kalita, Debaprasad Maity
Primordial Black Holes (PBHs) forming prior to Big Bang Nucleosynthesis evolve during the reheating epoch, an environment dominated by an oscillating inflaton field decaying into a…
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…
Impact of general relativistic accretion on primordial black holes
Santabrata Das, Md Riajul Haque, Jitumani Kalita +2
We demonstrate that general relativistic corrections to the accretion of relativistic matter onto primordial black holes (PBHs) can significantly enhance their mass growth during t…
Revisiting PBH accretion, evaporation and their cosmological consequences
Jitumani Kalita, Debaprasad Maity
Primordial black holes (PBHs) provide a unique probe of the early Universe. Their cosmological evolution is governed by the competition between mass accretion and Hawking evaporati…
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…
