The thermal emission in short GRBs with extended emission observed by Fermi/GBM
Xue-Zhao Chang, Hou-Jun Lü, Xing Yang +2
Short gamma-ray bursts (SGRBs) with extended emission (EE) are composed of initial main emission (ME) with a short-hard spike, followed by a long-lasting EE. Whether the ME and EE…
The progenitor and central engine of a peculiar GRB 230307A
ZhaoWei Du, HouJun Lü, Yong Yuan +2
Recently, a lack of supernova-associated long-duration gamma-ray burst (GRB 230307A) at such a low redshift , but associated with a possible kilonova emission, has attract…
Prompt-to-afterglow transition of optical emission in a long gamma-ray burst consistent with a fireball
Liping Xin, Xuhui Han, Huali Li +19
Long gamma-ray bursts (GRBs), which signify the end-life collapsing of very massive stars, are produced by extremely relativistic jets colliding into circumstellar medium. Huge ene…
Detection of Quasi-periodic Oscillations in SGR 150228213
Run-Chao Chen, Can-Min Deng, Xiang-Gao Wang +5
The detection of quasi-periodic oscillations (QPOs) in magnetar giant flares (GFs) has brought a new perspective to study the mechanism of magnetar bursts. Due to the scarcity of G…
A 31.3 day Transient Quasiperiodic Oscillation in Gamma-ray Emission from Blazar S5 0716+714
Junping Chen, Tingfeng Yi, Yunlu Gong +4
We systematically search for quasiperiodic oscillatory (QPO) signals on the month timescale among the 1525 sources given in the Fermi Large Area Telescope Light Curve Repository. W…
Thermal and nonthermal emission from a peculiar long-duration GRB 211211A
Xue-Zhao Chang, Hou-Jun Lü, Xing Yang +2
Long-duration GRB 211211A that lacks a supernova emission even down to very stringent limits at such a low redshift and is associated with kilonova emission, suggests tha…
Fermi Observations of GRB 220426A: a burst similar to GRB 090902B
Li-Tao Deng, Da-Bin Lin, Li Zhou +7
We report on a very bright, long-duration gamma-ray burst (GRB), GRB~220426A, observed by \emph{Fermi} satellite. GRB~220426A with total duration of ~s is composed with t…
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…
Evidence for gravitational lensing of GRB 200716C
Xing Yang, Hou-Jun Lü, Hao-Yu Yuan +4
Observationally, there is a small fraction of Gamma-ray bursts (GRBs) with prompt emission observed by Fermi/GBM that are composed of two pulses. Occasionally, the distance to a GR…
Highly Variable -Ray Emission of CTD 135 and Implications for its Compact Symmetric Structure
Ying-Ying Gan, Hai-Ming Zhang, Jin Zhang +4
The -ray emission properties of CTD 135, a typical compact symmetric object (CSO), are investigated with 11-year Fermi/LAT observations. We show that it has bright and sig…

S. S. Sun, H. L. Li, X. Yang +3
We here report a monitor of the BL Lac object 1ES 1218+304 in both B- and R-bands by the GWAC-F60A telescope in eight nights, when it was triggerd to be at its highest X-ray flux i…
Detection of a high-confidence quasi-periodic oscillation in radio light curve of the high redshift FSRQ PKS J0805-0111
Guo-Wei Ren, Hao-Jing Zhang, Xiong Zhang +5
In this work, we have searched quasi-periodic oscillations (QPOs) in the 15 GHz light curve of the FSRQ PKS J0805-0111 monitored by the Owens Valley Radio Observatory (OVRO) 40 m t…
