Detecting ultralight dark matter in the Galactic Center with pulsars around Sgr A*
Jiang-Chuan Yu, Yan Cao, Zexin Hu +1
Ultralight dark matter (ULDM) model is a leading dark matter candidate that arises naturally in extensions of the Standard Model. In the Galactic Center, ULDM manifests as dense hy…

Probing vector gravitational atoms with eccentric intermediate mass-ratio inspirals
Yan Cao, Ya-Ze Cheng, Gen-Liang Li +1
Ultralight bosons, proposed as candidates for dark matter (DM), are predicted by various new physics models. In the presence of bosons with suitable masses, superradiant (SR) insta…

Effects of black hole environments on extreme mass-ratio hyperbolic encounters
Ya-Ze Cheng, Yan Cao, Yong Tang
Extreme mass-ratio hyperbolic encounters (EMRHEs) around the supermassive black holes will be observable at the future gravitational-wave (GW) detectors in space, such as LISA and…
