Short Spike, Long Story: Episode-Dependent Shifts of Long-Duration Type-I GRBs on -- Plane
Ya-Hui Jiang, Run-Chao Chen, Zhen-Yu Yan +3
Observations of peculiar GRBs have challenged the traditional -based classification, demonstrating that duration does not map uniquely onto progenitor type. A striking clas…
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…
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…
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…
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…
Repeated partial disruptions in a WD-NS or WD-BH merger modulate the prompt emission of long-duration merger-type GRBs
Junping Chen, Rong-Feng Shen, Wen-Jun Tan +4
The progenitors of gamma-ray bursts (GRBs) have long been an unresolved issue. GRB 230307A stands out as an exceptionally bright event, belonging to the long-duration GRBs but also…
Triggering the Untriggered: The First Einstein Probe-Detected Gamma-Ray Burst 240219A and Its Implications
Yi-Han Iris Yin, Bin-Bin Zhang, Jun Yang +49
The Einstein Probe (EP) achieved its first detection and localization of a bright X-ray flare, EP240219a, on 2024 February 19, during its commissioning phase. Subsequent targeted s…
A Comptonized Fireball Bubble Fits the Second Extragalactic Magnetar Giant Flare GRB 231115A
Yi-Han Iris Yin, Zhao Joseph Zhang, Jun Yang +4
Magnetar giant flares (MGFs), originating from noncatastrophic magnetars, share noteworthy similarities with some short gamma-ray bursts (GRBs). However, understanding their detail…
