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…
Statistical analysis of multi-band plateaus in gamma-ray burst afterglows
Xiao-Yan Li, Tong Liu, Bao-Quan Huang +1
Plateau features are frequently observed in the afterglows of gamma-ray bursts (GRBs), yet their physical origins remain under debate. In this work, we compile a sample of 124 GRBs…
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…
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…
Black hole growths in gamma-ray bursts driven by the Blandford-Znajek mechanism
Xiao-Yan Li, Tong Liu
The Blandford-Znajek (BZ) mechanism in stellar-mass black hole (BH) hyperaccretion systems is generally considered to power gamma-ray bursts (GRBs). Based on observational GRB data…
