Prospects of calibrating afterglow modeling of short GRBs with gravitational wave inclination angle measurements and resolving the Hubble tension with a GW-GRB association event
Yi-Ying Wang, Shao-Peng Tang, Xin-Yu Li +2
In the numerical modeling of the GRB afterglow, some approximations have been made for simplicity, and different groups developed their codes. A robust test of these models/approac…
Mass and effective spin distributions of binary black hole events: Evidence for a population of hierarchical black hole mergers in active galactic nuclei disks
Yuan-Zhu Wang, Yi-Zhong Fan, Shao-Peng Tang +2
The origins of the coalescing binary black holes (BBHs) detected by the advanced LIGO/Virgo are still in debate and clues may present in the mass and effective spin ()…
Population properties of neutron stars in the coalescing compact binaries
Yin-Jie Li, Shao-Peng Tang, Yuan-Zhu Wang +3
We perform a hierarchical Bayesian inference to investigate the population properties of the coalescing compact binaries involving at least one neutron star (NS). With the current…
GRB 200716C: Evidence for a Short Burst Being Lensed
Yun Wang, Lu-Yao Jiang, Cheng-Kui Li +5
A tiny fraction of observed gamma-ray bursts (GRBs) may be lensed. The time delays induced by the gravitational lensing are milliseconds to seconds if the point lenses are intermed…
Black Hole Gravitational Potential Enhanced Fallback Accretion onto the Nascent Lighter Compact Object: Tentative Evidence in the O3 Run Data of LIGO/Virgo
Shao-Peng Tang, Yin-Jie Li, Yuan-Zhu Wang +2
In a binary system, the gravitational potential of the primary black hole may play an important role in enhancing the fallback accretion onto the lighter compact object newly forme…
Constraints on the phase transition and nuclear symmetry parameters from PSR and multimessenger data of other neutron stars
Shao-Peng Tang, Jin-Liang Jiang, Ming-Zhe Han +2
Recently, the radius of neutron star (NS) PSR J0740+6620 was measured by Neutron Star Interior Composition Explorer (NICER) and an updated measurement of neutron skin thickness of…
Black Hole Mass Function of Coalescing Binary Black Hole Systems: Is There a Pulsational Pair Instability Mass Cutoff?
Yuan-Zhu Wang, Shao-Peng Tang, Yun-Feng Liang +5
We analyze the LIGO/Virgo GWTC-2 catalog to study the primary mass distribution of the merging black holes. We perform hierarchical Bayesian analysis, and examine whether the mass…
Quasinormal-modes of the Kerr-Newman black hole: GW150914 and fundamental physics implications
Hai-Tian Wang, Shao-Peng Tang, Peng-Cheng Li +1
We develop an analytical ringdown waveform model, including both the fundamental and the overtone quasinormal modes, for charged black holes and show that it is precise enough to a…
Tight constraints on Einstein-dilation-Gauss-Bonnet gravity from GW190412 and GW190814
Hai-Tian Wang, Shao-Peng Tang, Peng-Cheng Li +2
Gravitational-wave (GW) data can be used to test general relativity in the highly nonlinear and strong field regime. Modified gravity theories such as Einstein-dilation-Gauss-Bonne…
Bayesian nonparametric inference of neutron star equation of state via neural network
Ming-Zhe Han, Jin-Liang Jiang, Shao-Peng Tang +1
We develop a new nonparametric method to reconstruct the Equation of State (EoS) of Neutron Star with multimessenger data. As an universal function approximator, the Feed-Forward N…
