Self-Interacting Sterile Neutrino Cold Dark Matter: Resonant Production Mechanism in the Early Universe

Eung Jin Chun, Kenji Kadota, Seokhoon Yun

Sterile neutrinos are well-motivated dark matter candidates, but their conventional production through active-sterile mixing is tightly constrained by X-ray searches and structure-…

Gravitational wave probes on self-interacting dark matter surrounding an intermediate mass black hole

Kenji Kadota, Jeong Han Kim, Pyungwon Ko +1

The presence of dark matter overdensities surrounding a black hole can influence the evolution of a binary system. The gravitational wave signals emitted by a black hole binary off…

Impact of dark matter-baryon relative velocity on the 21cm forest

Hayato Shimabukuro, Kiyotomo Ichiki, Kenji Kadota

We study the effect of the relative velocity between the dark matter (DM) and the baryon on the 21cm forest signals. The DM-baryon relative velocity arises due to their different e…

Boosting the 21 cm forest signals by the clumpy substructures

Kenji Kadota, Pablo Villanueva-Domingo, Kiyotomo Ichiki +2

We study the contribution of subhalos to the 21 cm forest signal. The halos can host the substructures and including the effects of those small scale clumps can potentially boost t…

Radio bounds on the mixed dark matter scenarios of primordial black holes and WIMPs

Kenji Kadota, Hiroyuki Tashiro

We study the synchrotron radio emission in the mixed dark matter scenarios consisting of the primordial black holes (PBHs) and the self-annihilating WIMPs (weakly interacting massi…

Primordial black hole dark matter in the presence of p-wave WIMP annihilation

Kenji Kadota, Hiroyuki Tashiro

We study the allowed primordial black hole (PBH) dark matter abundance in the mixed dark matter scenarios consisting of PBHs and self-annihilating weakly interacting massive partic…
