Reconstructing the Dark Matter Equation of State with Compact Object Inspirals
Boris Betancourt Kamenetskaia, Qianhang Ding, Hui-Yu Zhu
We investigate the gravitational wave (GW) signatures of compact binaries embedded in extended dark matter (DM) configurations in hydrostatic equilibrium. If a neutron star is surr…
Reconstruction of Primordial Power Spectrum from Gravitational Waves of High-Redshift Black Hole Binaries
Qianhang Ding, Xinpeng Wang, Masahide Yamaguchi +1
High-redshift binary black hole (BBH) events are promising candidates for primordial black holes (PBHs) detectable by next-generation gravitational wave (GW) detectors. A redshifte…
Gravitational Waves from Mergers of Asymmetric Dark Stars
Boris Betancourt Kamenetskaia, Qianhang Ding, Chris Kouvaris
A strongly self-interacting component of asymmetric dark matter (DM) particles can form compact dark stars (DSs). These objects have a broad spectrum of masses and radii, with dist…
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…
The merger rate of primordial black hole binaries as a probe of Hubble parameter
Qianhang Ding
We propose that the merger rate of primordial black hole (PBH) binaries can be a probe of Hubble parameter by constraining PBH mass function in the redshifted mass distribution of…
