SN 2025fhm: A central-engine powered Ic-BL supernova associated with X-ray transient EP250304a
Cui-Ying Song, Nan Jiang, Xiaofeng Wang +32
We present X-ray, optical, and radio follow-up observations of EP250304a, an extragalactic fast X-ray transient (EFXT) discovered by the Einstein Probe. Its X-ray light curve exhib…
SN 2024iss: A Double-peaked Type IIb Supernova with Evidence of Circumstellar Interaction
Liyang Chen, Xiaofeng Wang, Qinyu Wu +54
We present optical, ultraviolet, and X-ray observations of supernova (SN) 2024iss, a Type IIb SN that shows a prominent double-peaked light curve. We modeled the first peak with a…
The Red Supergiant Progenitor of Type II Supernova 2024ggi
Danfeng Xiang, Jun Mo, Xiaofeng Wang +8
We present a detailed analysis of the progenitor and its local environment for the recently discovered type II supernova (SN) 2024ggi at a distance of about 6.7~Mpc, by utilizing t…
Tianyu: search for the second solar system and explore the dynamic universe
Fabo Feng, Yicheng Rui, Zhimao Du +32
Giant planets like Jupiter and Saturn, play important roles in the formation and habitability of Earth-like planets. The detection of solar system analogs that have multiple cold g…
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…
Long-duration Gamma-ray Burst Progenitors and Magnetar Formation
Cui-Ying Song, Tong Liu
Millisecond magnetars produced in the center of dying massive stars are one prominent model to power gamma-ray bursts (GRBs). However, their detailed nature remains a mystery. To e…
Testing Blandford-Znajek mechanism in black hole hyperaccretion flows for long-duration gamma-ray bursts
Mei Du, Shuang-Xi Yi, Tong Liu +2
Long-duration gamma-ray bursts (GRBs) are generally related to the core-collapse of massive stars. In the collapsar scenario, a rotating stellar-mass black hole (BH) surrounded by…
Neutrino-dominated accretion flows: second nucleosynthesis factory in core-collapse supernovae and regulation of iron markets in galaxies
Tong Liu, Yan-Qing Qi, Zhen-Yi Cai +3
Cosmic metals are widely believed to be produced by supernovae (SNe) and compact object mergers. Here, we discuss the nucleosynthesis of neutrino-dominated accretion flows (NDAFs)…
Neutrinos and gravitational waves from magnetized neutrino-dominated accretion discs with magnetic coupling
Cui-Ying Song, Tong Liu, Yun-Feng Wei
Gamma-ray bursts (GRBs) might be powered by a black hole (BH) hyperaccretion systems via the Blandford-Znajek (BZ) mechanism or neutrino annihilation from neutrino-dominated accret…
Black hole hyperaccretion in collapsars. I. MeV neutrinos
Yun-Feng Wei, Tong Liu, Cui-Ying Song
As the plausible central engine of gamma-ray bursts (GRBs), a black hole (BH) hyperaccretion disk should be in a state of neutrino-dominated accretion flow (NDAF) if the accretion…
A possible feedback mechanism of outflows from a black hole hyperaccretion disk in the center of jet-driven iPTF14hls
Tong Liu, Cui-Ying Song, Tuan Yi +2
iPTF14hls is an unusually bright, long-lived II-P supernova (SN), whose light curve has at least five peaks. We propose that the outflows from the black hole hyperaccretion systems…
Black hole hyperaccretion inflow-outflow model. II. Long-duration gamma-ray bursts and supernova bumps
Cui-Ying Song, Tong Liu
Long-duration gamma-ray bursts (LGRBs) associated with supernovae (SNe) are possibly born out of the death of a massive star. After the star collapses, a stellar-mass black hole (B…
Compact binary merger and kilonova: outflows from remnant disc
Tuan Yi, Wei-Min Gu, Tong Liu +3
Outflows launched from a remnant disc of compact binary merger may have essential contribution to the kilonova emission. Numerical calculations are conducted in this work to study…
Black hole hyperaccretion inflow-outflow model. I. long and ultra-long gamma-ray bursts
Tong Liu, Cui-Ying Song, Bing Zhang +2
Long-duration gamma-ray bursts (LGRBs) and ultra-LGRBs (ULGRBs) originate from collapsars, in the center of which a newborn rotating stellar-mass black hole (BH) surrounded by a ma…
Comparison of gravitational waves from central engines of gamma-ray bursts: neutrino-dominated accretion flows, Blandford-Znajek mechanisms, and millisecond magnetars
