The Magnetic Origin of Primordial Black Holes: Ultralight PBHs and Secondary GWs
Subhasis Maiti, Debaprasad Maity
Ultralight primordial black holes (PBHs) provide a compelling window into early-Universe cosmology. Following our earlier work, we explore a mechanism for the formation of ultralig…
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…
Dark matters are Inert, or FIMPy, or WIMPy or UFOy: An inflationary gravitational particle production
Ayan Chakraborty, Debaprasad Maity, Rajesh Mondal
In this letter, we explore the phenomenological impact of inflationary gravitational particle production in the physics of Dark Matter (DM). Large-scale DM fluctuations generated d…
Extreme mass ratio inspirals in the cold vector dark matter environment
Rajesh Karmakar, Debaprasad Maity, Kaustubh Mukund Vispute
With regard to the observed dark matter density profile in galaxies and clusters, the scalar dark matter scenario has been previously studied for potential detectability through gr…
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…
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…
