Superradiant evolution of the shadow and photon ring of Sgr A
Yifan Chen, Rittick Roy, Sunny Vagnozzi +1
Ultralight bosons can affect the dynamics of spinning black holes (BHs) via superradiant instability, which can lead to a time evolution of the supermassive BH shadow. We study pro…

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…
