Free-free background radiation from accreting primordial black holes
Hiroyuki Tashiro, Katsuya T. Abe, Teppei Minoda
Baryonic gas falling onto a primordial black hole (PBH) emits photons via the free-free process. These photons can contribute the diffuse free-free background radiation in the freq…
Small-scale CMB anisotropies induced by the primordial magnetic fields
Teppei Minoda, Kiyotomo Ichiki, Hiroyuki Tashiro
The primordial magnetic fields (PMFs) produced in the early universe are expected to be the origin of the large-scale cosmic magnetic fields. The PMFs are considered to leave a foo…
Thermal Sunyaev-Zel'dovich Effect in the IGM due to Primordial Magnetic Fields
Teppei Minoda, Kenji Hasegawa, Hiroyuki Tashiro +2
In the present universe, magnetic fields exist with various strengths and on various scales. One possible origin of these cosmic magnetic fields is the primordial magnetic fields (…
Insight into primordial magnetic fields from 21-cm line observation with EDGES experiment
Teppei Minoda, Hiroyuki Tashiro, Tomo Takahashi
The recent observation of the 21-cm global absorption signal by EDGES suggests that the intergalactic medium (IGM) gas has been cooler than the cosmic microwave background during $…
