Tightening Bounds on Warm Dark Matter with High-Redshift Gamma-Ray Bursts
Jun-Jie Wei, Jing-Meng Hao, Ding-Fang Hu +4
The paper uses Swift gamma‑ray burst observations at redshifts up to 10 to place lower limits on the mass of warm dark matter particles, finding mₓ ≳ 1.3 keV (or ≳ 3.4 keV if the G…

GRB Timing: Decoding the Hidden Slow Jets in GRB 060729
Jin-Jun Geng, Ding-Fang Hu, Hao-Xuan Gao +16
Gamma-ray bursts (GRBs) are luminous stellar explosions characterized by the ejection of relativistic jets. This work proposes a novel paradigm to study these GRB jets. By analyzin…

Quasi-thermal Photosphere Emission from Structured Jets of Gamma-Ray Bursts
Ding-Fang Hu, Jin-Jun Geng, Hao-Xuan Gao +2
The prompt emission of gamma-ray bursts (GRBs) is supposed to be released from the relativistic jet launched from the central engine. Apart from the non-thermal nature of the spect…
