A statistical relation of energy injection plateaus in multi-band afterglows of gamma-ray bursts
Xiao-Yan Li, Tong Liu, Bao-Quan Huang
The origin of the plateau phase in gamma-ray burst (GRB) afterglows remains under debate, with the energy injection model being one of the most competitive explanations. If the pla…
Impact of Neutrino Flavour Conversion on the Diffuse Neutrino Background from Neutrino-dominated Accretion Flows
Yun-Feng Wei, Tong Liu
Neutrino-dominated accretion flows (NDAFs) are believed to form during the fallback accretion phase of some core-collapse supernovae (CCSNe). Such systems produce copious neutrino…
Impact of disk magnetic fields on the propagation of stellar-scale jets in the magnetically arrested accretion disks of active galactic nuclei
Bao-Quan Huang, Tong Liu, Jian-Fu Zhang
It is widely recognized that active galactic nucleus (AGN) disks host numerous massive stars and compact objects. Stellar-scale jets triggered by collapses of massive stars and mer…
Imprints of gravitational waves from magnetar spindown in GRB X-ray afterglows
Shu-Jin Hou, Rui Xue, Fang-Kun Peng +3
Given that newborn magnetars are considered potential central engines of gamma-ray bursts (GRBs), there is strong motivation to identify gravitational wave (GW) signatures within G…
Hyperaccretion-driven relativistic jets from massive collapsars in active galactic nucleus disks
Yun-Feng Wei, Tong Liu, Bao-Quan Huang
The observable characteristics of gamma-ray bursts (GRBs) embedded in the accretion disk of active galactic nuclei (AGNs) are mainly determined by the jet propagation within the di…
Anisotropy of core-collapse supernovae effected by AGN disks
Jiao-Zhen She, Tong Liu, Bao-Quan Huang +4
Active galactic nucleus (AGN) disk provide dense environments to influence on the star formation, evolution, and migration. In AGN disks, pressure gradients and migration accelerat…
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…
