The Sunyaev-Zel'dovich effect and Faraday rotation contributions of galaxy groups to the CMB angular power spectrum
Hiroyuki Tashiro, Joseph Silk, Mathieu Langer +1
The S-Z effect and Faraday rotation from halos are examined over a wide mass range, an including gas condensation and magnetic field evolution. Contributions to the CMB angular pow…
The cross-correlation of the CMB polarisation and the 21-cm line fluctuations from cosmic reionisation
Hiroyuki Tashiro, Nabila Aghanim, Mathieu Langer +2
The cosmic microwave background (CMB) polarisation and the 21 cm line fluctuations are powerful probes of cosmological reionisation. We study how the cross-correlation between the…
Constraints on Primordial Black Holes by Distortions of Cosmic Microwave Background
Hiroyuki Tashiro, Naoshi Sugiyama
Possible influence of primordial black hole (PBH) evaporations on cosmic microwave background (CMB) is investigated. The spectrum distortions of CMB from the black-body spectrum ar…
Secondary B-mode polarization from Faraday rotation in clusters and galaxies
Hiroyuki Tashiro, Nabila Aghanim, Mathieu Langer
We revisit the polarisation induced by Faraday rotation when Cosmic Microwave Background photons traverse magnetised plasma. We compute the secondary B-mode angular power spectrum…
Probing Primordial Magnetic Fields with the 21cm Fluctuations
Hiroyuki Tashiro, Naoshi Sugiyama
Primordial magnetic fields possibly generated in the very early universe are one of the candidates for the origin of magnetic fields observed in many galaxies and galaxy clusters.…
The early reionization with the primordial magnetic fields
Hiroyuki Tashiro, Naoshi Sugiyama
The early reionization of the intergalactic medium, which is favored from the WMAP temperature-polarization cross-correlations, contests the validity of the standard scenario of st…
