Revisiting black hole hyperaccretion in the center of gamma-ray bursts for the lower mass gap
Hui-Min Qu, Tong Liu
The ultrarelativistic jets triggered by neutrino annihilation processes or Blandford-Znajek (BZ) mechanisms in stellar-mass black hole (BH) hyperaccretion systems are generally con…
Probing cosmic anisotropy with GW/FRB as upgraded standard sirens
Rong-Gen Cai, Tong-Bo Liu, Shao-Jiang Wang +1
Recently it was shown that cosmic anisotropy can be well tested using either standard siren measurement of luminosity distance from gravitational-wave (GW) observ…
The GWs from the S-stars revolving around the SMBH at Sgr A*
Rong-Gen Cai, Tong-Bo Liu, Shao-Jiang Wang
A preliminary estimation of gravitational waves (GWs) from the extreme-mass-ratio-inspirals (EMRIs) system in the Galactic Centre (GC) is given for the 37 observed S-stars revolvin…
Sensitivity of primordial black hole abundance on the reheating phase
Rong-Gen Cai, Tong-Bo Liu, Shao-Jiang Wang
We investigate the sensitivity of reheating history on the abundance of primordial black holes (PBHs). Contrary to the monochromatic case of mass fraction of PBH, reheating era wit…
