Probing blackbody components in gamma-ray bursts from black hole neutrino-dominated accretion flows
Xiao-Yan Li, Tong Liu, Bao-Quan Huang +4
A stellar-mass black hole (BH) surrounded by a neutrino-dominated accretion flow (NDAF) is generally considered to be the central engine of gamma-ray bursts (GRBs). Neutrinos escap…
A Neutron Capture Explanation for the 10 MeV Emission Line Seen in GRB 221009A
Jiahuan Zhu, Hua Feng, Tong Liu
The brightest ever gamma-ray burst (GRB) 221009A displays a significant emission line component around 10 MeV. As the GRB central engine is neutron-rich, we propose that the emissi…
Laboratorial radiative shocks with multiple parameters and first quantifying verifications to core-collapse supernovae
Lu Zhang, Jianhua Zheng, Zhenghua Yang +20
We present experiments to reproduce the characteristics of core-collapse supernovae with different stellar masses and initial explosion energies in the laboratory. In the experimen…
Stochastic gravitational wave background from cosmological neutrino-dominated accretion flows
Yun-Feng Wei, Tong Liu
We investigate the stochastic gravitational wave background (SGWB) from neutrino-dominated accretion flows (NDAFs) based on the results of our fallback core-collapse supernova (CCS…
GRB afterglows with energy injections in AGN accretion disks
Bao-Quan Huang, Tong Liu, Xiao-Yan Li +1
Active galactic nucleus (AGN) disks are widely considered potential hosts for various high-energy transients, including gamma-ray bursts (GRBs). The reactivation of GRB central eng…
Contribution of neutrino-dominated accretion flows to cosmic MeV neutrino background
Yun-Feng Wei, Tong Liu, Cui-Ying Song
Neutrino-dominated accretion flows (NDAFs) are one of the important MeV neutrino sources and significantly contribute to the cosmic diffuse neutrino background. In this paper, we i…
