A new constraint on the Hawking evaporation of primordial black holes in the radiation-dominated era

Seyed Sajad Tabasi, Javad T. Firouzjaee

In this paper, we revisit the evaporation and accretion of primordial black holes (PBHs) during cosmic history and compare them to see if both of these processes are constantly act…
