Turbulent Transport of Galactic Magnetic Fields into Cosmic Voids: Insights from IllustrisTNG
Yuri Yamashita, Hiroyuki Tashiro, Kiyotomo Ichiki
Astrophysical processes associated with galaxies may contribute to the magnetization of cosmic voids. We investigate the diffusion of galactic magnetic fields in an expanding unive…

Probing the mass relation between supermassive black holes and dark matter halos at high redshifts by gravitational wave experiments
Kazuya Furusawa, Hiroyuki Tashiro, Shuichiro Yokoyama +1
Numerous observations have shown that almost all galaxies in our Universe host supermassive black holes (SMBHs), but there is still much debate about their formation and evolutiona…

Revisiting constraints on primordial magnetic fields from spectral distortions of cosmic microwave background
Fumio Uchida, Kohei Kamada, Hiroyuki Tashiro
The magneto-hydrodynamic decay of primordial magnetic fields can distort the black-body spectrum of the cosmic microwave background (CMB) by draining magnetic energy into thermal p…
