Harmonic brightness oscillations point to magnetar giant flares in rare short gamma-ray bursts
Run-Chao Chen, Ore Gottlieb, Bin-Bin Zhang +5
Kilohertz quasi-periodic oscillations (QPOs) have been observed in a few rare gamma-ray bursts (GRBs), but their physical origin remains uncertain. We reanalyze the two short GRBs…
Large offsets of double-neutron-star mergers: degeneracies and implications for host associations
Xiao-Tian Xu, Bin-Bin Zhang, Wenjie Wu +1
The projected offset of a Gamma-Ray Burst (GRB) from its host galaxy is an important diagnostic of its physical origin, where the host associations are usually evaluated through ch…
Explosions in the Empty: A Survey of Transients in Local Void Galaxies
Suo-Ning Wang, Bin-Bin Zhang, Rubén García-Benito
We present a systematic analysis of transient astrophysical events -- including supernovae (SNe), gamma-ray bursts (GRBs), and fast radio bursts (FRBs) -- in void and non-void gala…
The color evolution of magnetar-powered kilonova emission in merging neutron star-neutron star systems
Suo-Ning Wang, Hou-Jun Lü, Xiao-Xuan Liu +3
The first direct detection of the gravitational wave (GW) event GW170817 and its electromagnetic (EM) counterpart open a new window for studying of multi-messenger astronomy. Howev…
Ejecta-circumstellar medium interaction in high-density environment contribution to kilonova emission: Application to GRB 191019A
Suo-Ning Wang, Hou-Jun Lü, Yong Yuan +4
The nearby long-duration GRB 191019A recently detected by Swift lacks an associated supernova and belongs to a host galaxy with little star formation activity, suggesting that the…
