Probing Heavy Dark Matter in Red Giants
Sougata Ganguly, Minxi He, Chang Sub Shin +2
Red giants (RGs) provide a promising astrophysical environment for capturing dark matter (DM) via elastic scattering with stellar nuclei. Captured DM particles migrate toward the h…
Extracting Properties of Dark Dense Environments around Black Holes from Gravitational Waves
Qianhang Ding, Minxi He, Hui-Yu Zhu
Dark matter (DM) can form dense condensates around black holes (BHs), such as superradiant clouds and ultracompact mini halos, which can significantly affect the orbital evolution…
Dark Matter-Independent Orbital Decay Bounds on Ultralight Bosons from OJ287
Qianhang Ding, Minxi He, Volodymyr Takhistov +1
Ultralight bosons, predicted in scenarios beyond the Standard Model and viable dark matter (DM) candidates, can form superradiant clouds around spinning black holes influencing the…
Primordial Black Hole Mergers as Probes of Dark Matter in Galactic Center
Qianhang Ding, Minxi He, Volodymyr Takhistov
Primordial black holes (PBHs) from the early Universe that can contribute to dark matter (DM) abundance have been linked to gravitational wave observations. Super-massive black hol…
