CMB signatures of gravity-mediated dark radiation in
Anish Ghoshal, Sk Jeesun, Kazunori Kohri
Measurement of in the CMB (Cosmic Microwave Background) observations, like Planck 2018 and BBN (Big Bang Nucleosynthesis) has already set stringent constraints on the…

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…

Thermalization and hotspot formation around small primordial black holes
Minxi He, Kazunori Kohri, Kyohei Mukaida +1
We quantitatively analyze a basic question: what is the stationary solution of the background plasma temperature profile around a black hole (BH)? One may naively expect that the t…
