Implications of Cosmic Birefringence for Multi-Field ALP Dark Matter
Jialiang Shao, Ippei Obata, Dongdong Zhang
Cosmic birefringence, characterized by the observed rotation of the polarization plane of the cosmic microwave background (CMB) radiation, serves as a critical probe for testing th…

Constraining Ultralight ALP Dark Matter in Light of Cosmic Birefringence
Dongdong Zhang, Elisa G. M. Ferreira, Ippei Obata +1
Cosmic birefringence, the observed rotation of the polarization plane of the cosmic microwave background (CMB), serves as a compelling probe for parity-violating physics beyond the…
