Microscopy assessment of two multiple-transient candidates

Jun Yang, Beatriz Villarroel

We present a microscopy-based assessment of two representative cases of multiple-transient candidates identified on historical photographic plates: the nine-transient event of 12 A…

A 4.5-s Quasiperiodic Spectral Oscillation in GRB 230307A: Evidence for Free Precession of a Post-Merger Magnetar?

Run-Chao Chen, Jun Yang, Bin-Bin Zhang +4

Millisecond magnetars, rapidly rotating neutron stars with ultra-strong magnetic fields, have long been proposed as central engines of gamma-ray bursts (GRBs). For GRBs produced by…

Jet-Structure Imprint on the Curvature Tail of Gamma-Ray Burst Prompt Emission

Zhen-Yu Yan, Xiao-Hong Zhao, Hendrik J. van Eerten +7

Even though the prompt emission of gamma-ray bursts (GRBs) is highly beamed, high-latitude emission still produces a distinct light curve break after the intrinsic emission ceases…

Detection of a Millisecond Periodicity in BATSE Short Gamma-Ray Bursts

Run-Chao Chen, Jun Yang, Yi-Han Iris Yin +1

Coherent oscillations at kilohertz frequencies have recently been detected in a small number of gamma-ray bursts (GRBs), suggesting quasi-periodic dynamics in their central engines…

Minutes-long soft X-ray prompt emission from a compact object merger

An Li, Chen-Wei Wang, Niccolò Passaleva +75

Compact object mergers are multi-messenger sources and known progenitors of some gamma-ray bursts, bright flashes of high-energy radiation powered by a central engine, either an ac…

Fast-Cooling Synchrotron Prompt Emission from Internal Shocks in GRB 241030A

Varun, Bin-Bin Zhang, Xiao-Hong Zhao +3

We present a time-resolved, joint Swift-Fermi spectral study of GRB 241030A (z=1.411) that cleanly isolates the synchrotron origin of its prompt emission and favors a matter-domina…

Evidence for a brief appearance of gamma-ray periodicity after a compact star merger

Run-Chao Chen, Bin-Bin Zhang, Chen-Wei Wang +6

The product of a compact star merger is usually hypothesized to be a hyperaccreting black hole, typically resulting in a gamma-ray burst (GRB) with a duration shorter than 2~s. How…

A fast powerful X-ray transient from possible tidal disruption of a white dwarf

Dongyue Li, Wenda Zhang, Jun Yang +97

Stars captured by black holes (BHs) can be torn apart by strong tidal forces, producing electromagnetic flares. To date, more than 100 tidal disruption events (TDEs) have been obse…

Spectral Hardening Reveals Afterglow Emergence in Long-Duration Fast X-ray Transients: A Case Study of GRB 250404A/EP250404a

Yi-Han Iris Yin, Yuan Fang, Bin-Bin Zhang +56

The prompt emission and afterglow phases of gamma-ray bursts (GRBs) have been extensively studied, yet the transition between these two phases remains inadequately characterized du…

Extreme superluminal expansion traces an ultra-narrow GRB jet across relativistic regimes

Jin-Jun Geng, Ying-Kang Zhang, Hao-Xuan Gao +20

The long-term evolution of gamma-ray burst (GRB) jets from ultra-relativistic launch to a slowly expanding radio source remains a fundamental problem in high-energy astrophysics, r…

Multiwavelength Analysis of GRB 250101A: From Gamma-ray Prompt Emission to Optical Afterglow

Guowang Du, Yehao Cheng, Yuan-Pei Yang +15

The interaction between the relativistic jet and the circumburst medium produces a multiwavelength afterglow of a gamma-ray burst (GRBs). In this work, we present multiwavelength p…

What Powered the Kilonova-Like Emission After GRB 230307A in the Framework of a Neutron Star-White Dwarf Merger?

Xiangyu Ivy Wang, Yun-Wei Yu, Jia Ren +3

The second brightest gamma-ray burst, GRB 230307A (with a duration ~ 40 s), exhibited characteristics indicative of a magnetar engine during the prompt emission phase. Not…
