Testing the ALP-photon coupling with polarization measurements of Sagittarius A*
Guan-Wen Yuan, Ziqing Xia, Chengfeng Tang +5
Ultra-light bosons such as axions or axion-like particles (ALPs), are promising candidates to solve the dark matter problem. A unique way to detect such ALPs is to search for the p…
