LHAASO-WCDA observed a 5 days TeV-delayed flaring event in blazar 1ES 1959+650
Zhen Cao, F. Aharonian, Y. X. Bai +339
We report a day-scale hard lag between GeV and TeV -ray emission from the HBL 1ES~1959+650 in early 2024. Since the LHAASO-WCDA real-time monitoring system began operation in la…
Anisotropic Particle Transport from a Pulsar Wind Nebula Revealed by Einstein Probe and LHAASO
Zhen Cao, F. Aharonian, Y. X. Bai +339
Pulsar wind nebulae (PWNe) are major cosmic ray accelerators, yet the mechanisms transporting high-energy particles into the interstellar medium remain elusive. Building on the LHA…
The Extended Ultrahigh-energy Gamma-Ray Emission in the Vicinity of PSR J2238+5903
Zhen Cao, F. Aharonian, Y. X. Bai +324
We present a comprehensive analysis of the recently discovered TeV gamma-ray source, LHAASO J2238+5900. Based on data collected from the LHAASO, our fitting results suggest that th…
Einstein Probe Discovery of an X-ray Flare from K-type Star PM J23221-0301
Guoying Zhao, WeiKang Zheng, Rong-Feng Shen +21
Stellar flares are an intense stellar activity that can significantly impact the atmospheric composition of the surrounding planets and even the possible existence of life. During…
A period-increasing oscillation signal in a long gamma-ray burst
Tian-Ci Zheng, Stefano Covino, Yun Wang +3
Gamma-ray bursts (GRBs), the brightest electromagnetic bursts in the universe, are believed to originate from ultra-relativistic jets launched by the rapidly rotating central engin…
A Comprehensive Analysis of Insight-HXMT Gamma-Ray Burst Data. I. Power Density Spectrum
Zi-Min Zhou, Xiang-Gao Wang, En-Wei Liang +7
Power Density Spectrum (PDS) is one of the powerful tools to study light curves of gamma-ray bursts (GRBs). We show the average PDS and individual PDS analysis with {\it Hard X-ray…
SN 2019tua : A Type IIb Supernova with Multiple Bumps in the Light Curves
Xin-Bo Huang, Xiang-Gao Wang, Long Li +9
We present photometric and spectroscopic observations and analysis of the type IIb supernova (SN) SN 2019tua, which exhibits multiple bumps in its declining light curves between 40…
The Activity of Black Hole Imprints on the Internal Plateau and the Subsequent Sharp Decay
Tian-Ci Zheng, Da-Ming Wei, Yun Wang +2
A stellar-mass black hole (BH) or a millisecond magnetar is believed to be born as the central engine of Gamma-ray bursts (GRBs). The presence of plateaus in the X-ray extended emi…
A broken "-intensity" relation caused by the evolving photosphere emission and the nature of the extraordinarily bright GRB 230307A
Yun Wang, Zi-Qing Xia, Tian-Ci Zheng +2
GRB 230307A is one of the brightest gamma-ray bursts detected so far. With the excellent observation of GRB 230307A by Fermi-GBM, we can reveal the details of prompt emission evolu…
GRB 220426A: A Thermal Radiation-Dominated Gamma-Ray Burst
Yun Wang, Tian-Ci Zheng, Zhi-Ping Jin
The physical composition of the ejecta of gamma-ray bursts (GRBs) remains an open question. The radiation mechanism of the prompt gamma rays is also in debate. This problem can be…
Comparison of the Characteristics of Magnetars Born in Death of Massive Stars and Merger of Compact Objects With {\em Swift} Gamma-Ray Burst Data
Le Zou, En-Wei Liang, Shu-Qing Zhong +6
Assuming that the shallow-decaying phase in the early X-ray lightcurves of gamma-ray bursts (GRBs) is attributed to the dipole radiations (DRs) of a newborn magnetar, we present a…
GRB 101225A as Orphan Dipole Radiation of a Newborn Magnetar with Precession Rotation in an Off-Axis Gamma-Ray Burst
Le Zou, Tian-Ci Zheng, Xing Yang +5
The unusual multiwavelength lightcurves of GRB 101225A are revisited by assuming that it is from an off-axis GRB powered by a newborn magnetar. We show that its optical afterglow l…
X-ray Flares Raising upon Magnetar Plateau as an Implication of a Surrounding Disk of Newborn Magnetized Neutron Star
Tian-Ci Zheng, Long Li, Le Zou +1
The X-ray flares have usually been ascribed to long-lasting activities of the central engine of gamma-ray bursts (GRBs), e.g., fallback accretion. The GRB X-ray plateaus, however,…
A mag Super Flare of An Ultracool Star Detected by System
L. P. Xin, H. L. Li, J. Wang +21
In this paper, we report the detection and follow-ups of a super stellar flare GWAC\,181229A with an amplitude of 9.5 mag on a M9 type star by and the de…
No pulsed radio emission during a bursting phase of a Galactic magnetar
L. Lin, C. F. Zhang, P. Wang +45
Fast radio bursts (FRBs) are mysterious millisecond-duration radio transients of unknown origin observed at extragalactic distances. It has been long speculated that magnetars are…
