Population statistics of nanohertz gravitational wave sources
Jiming Yu, Zhen Pan, Xiao Xue +1
The recent detection of a nanohertz gravitational wave (GW) background by pulsar timing arrays (PTA) has sparked extensive discussions regarding its origin-whether it arises from a…
Sub-parsec precision measurement of pulsar distances with nanohertz gravitational waves
Jiming Yu, Zhen Pan
The recent evidence of nanohertz (nHz) gravitational wave (GW) background by pulsar timing array (PTA) collaborations has sparked considerable interest in understanding its astroph…
Improving the detection sensitivity to primordial stochastic gravitational waves with reduced astrophysical foregrounds. II. Subthreshold binary neutron stars
Mingzheng Li, Jiming Yu, Zhen Pan
Stochastic gravitational waves (GWs) consist of a primordial component from early Universe processes and an astrophysical component from compact binary mergers. To detect the primo…
Measuring the Hubble constant with coalescences of binary neutron star and neutron star-black hole: bright sirens \& dark sirens
Jiming Yu, Zhengyan Liu, Xiaohu Yang +4
The observations of gravitational wave (GW) provide us a new probe to study the universe. GW events can be used as standard sirens if their redshifts are measured. Normally, starda…
