Forecast constraints on the axion-photon coupling from interstellar medium heating
Makoto Amakawa, Tomohiro Fujita, Shinji Tsujikawa
In interstellar media characterized by a nonrelativistic plasma of electrons and heavy ions, we study the effect of axion dark matter coupled to photons on the dynamics of an elect…

Low-Scale Inflationary Magnetogenesis without Baryon Isocurvature Problem
Kazuki Yanagihara, Fumio Uchida, Tomohiro Fujita +1
Primordial magnetogenesis is an intriguing possibility to explain the origin of intergalactic magnetic fields (IGMFs). However, the baryon isocurvature problem has recently been po…
