Primordial Black Hole Formation and Spin in Matter Domination Revisited
Weitao Ye, Yungui Gong, Tomohiro Harada +4
In this article, we calculate the mass distribution of primordial black holes (PBHs) formed in the matter-dominated (MD) era by the peak theory. We apply the Zel'dovich approximati…
Primordial black hole formation from a type II perturbation in the absence and presence of pressure
Koichiro Uehara, Albert Escrivà, Tomohiro Harada +2
We investigate primordial black holes (PBHs) formed from extremely large amplitudes of primordial curvature fluctuations, classified as type II. Type II fluctuations differ from ty…
General relativistic effects on photon spectrum emitted from dark matter halos around primordial black holes
Toya Suzuki, Takahisa Igata, Kazunori Kohri +1
We investigate general relativistic effects on the photon spectrum emitted from decaying (or annihilating) particle dark matter in the halo surrounding a primordial black hole. The…
