Universal scaling between magnetar field and initial spin period for short gamma ray bursts
Qin-Mei Li, Qi-Bin Sun, Sheng-Bang Qian +5
The -- correlation serves as a critical probe of magnetar engine physics. Although this scaling relation has been firmly established for long gamma-ray bursts (lGRBs), sy…
New Evidence for Extragalactic Einstein Probe Transients associated with Long Gamma-ray Bursts
Qin-Mei Li, Qi-Bin Sun, Sheng-Bang Qian +1
The origin of extragalactic fast X-ray transients (EFXTs) remains a fundamental open question in high-energy astrophysics. The Einstein Probe (EP) mission provides a transformative…
The Cosmic Star Formation History: Insights from Kilonova-Associated Gamma-Ray Bursts
Qin-Mei Li, Qi-Bin Sun, Sheng-Bang Qian +2
The origin of the Universe and its material content remains one of the most fundamental questions in science. Gamma-ray bursts (GRBs), with their extreme luminosities and high-reds…
Orbital and Pulsation Analysis of 42 Heartbeat Stars Discovered in TESS Data
Min-Yu Li, Sheng-Bang Qian, Ai-Ying Zhou +7
Heartbeat stars (HBSs) are ideal laboratories for studying the formation and evolution of binary stars in eccentric orbits and their mutual tidal interactions. We present 42 new HB…
Heartbeat Stars Recognition Based on Recurrent Neural Networks: Method and Validation
Min-Yu Li, Sheng-Bang Qian, Li-Ying Zhu +7
Since the variety of their light curve morphologies, the vast majority of the known heartbeat stars (HBSs) have been discovered by manual inspection. Machine learning, which has al…
Detection of Low-Redshift Excess in Supernova-Linked Gamma-Ray Bursts
Qin-Mei Li, Qi-Bin Sun, Sheng-Bang Qian +1
Gamma-ray bursts (GRBs) are traditionally classified into long (lGRBs) and short (sGRBs) durations based on their , with lGRBs widely used as tracers of the cosmic star for…
