Constraints on the Primordial Black Hole Abundance using Pulsar Parameter Drifts
Yan-Chen Bi, Yu-Mei Wu, Qing-Guo Huang
Primordial black holes (PBHs) provide a compelling interpretation for the binary black holes (BBHs) observed by ground-based gravitational-wave (GW) detectors, especially for those…
Harmonic Analysis on Correlation for Gravitational-Wave Backgrounds of Arbitrary Polarization from Interfering Sources in Generic Dispersion Relation
Yan-Chen Bi, Yu-Mei Wu, Qing-Guo Huang
The Hellings-Downs (HD) correlation serves as the fundamental benchmark for detecting the gravitational-wave background (GWB) in pulsar timing arrays (PTAs) within General Relativi…
Spatial Correlation between Pulsars from Interfering Gravitational-Wave Sources in Massive Gravity
Yu-Mei Wu, Yan-Chen Bi, Qing-Guo Huang
In the nanohertz band, the spatial correlations in pulsar timing arrays (PTAs) produced by interfering gravitational waves (GWs) from multiple sources likely deviate from the tradi…
Targeted search for an individual SMBHB in NANOGrav 15-year and EPTA DR2 data sets
Li-Wen Tian, Yan-Chen Bi, Yu-Mei Wu +1
While pulsar timing array (PTA) collaborations have reported evidence for a stochastic gravitational wave background (GWB), the detection of continuous gravitational waves (GWs) fr…
