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…
Energy condition and cosmic censorship conjecture in the perfect fluid collapse
Javad T. Firouzjaee
The hypothesis of cosmic censorship plays a crucial role in classical general relativity, namely, to ensure that naked singularities would never occur from the black hole singulari…
Searching for the hydrogen 21 cm line in cosmos
Mahta Moazzenzadeh, Javad T. Firouzjaee
It is widely agreed that studying the 21 cm emission line from neutral hydrogen may be our best hope for understanding the creation of the first structures during the dark ages and…
The Integrated Sachs-Wolfe Effect in 4D Einstein-Gauss-Bonnet Gravity
Mina Ghodsi Y., Aryan Behnamfard, Saeed Fakhry +1
A novel 4-dimensional Einstein-Gauss-Bonnet (4D EGB) gravity has been proposed that asserts to bypass the Lovelock's theorem and to result in a non-trivial contribution to the grav…
Radiation from Einstein-Gauss-Bonnet de Sitter Black Hole via Tunneling Process
Sareh Eslamzadeh, Javad T. Firouzjaee, Kourosh Nozari
In this paper, we probe in 4D Einstein-Gauss-Bonnet black hole and its thermodynamics. We illustrate the three asymptotically 4D EGB spacetime as an asymptotically flat, de Sitter,…
Primordial Black Hole Merger Rate in Self-Interacting Dark Matter Halo Models
Saeed Fakhry, Mahdi Naseri, Javad T. Firouzjaee +1
We study the merger rate of primordial black holes (PBHs) in self-interacting dark matter (SIDM) halo models. To explore a numerical description for the density profile of SIDM hal…
