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…
X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
Measuring the Angular Auto-power Spectrum of Fast Radio Burst Dispersion Measures as a Robust Cosmological Probe and Baryon Tracer
Bao Wang, Zhiyu Lu, Yang Liu +2
Fluctuations in the cosmic electron density are imprinted on the dispersion measures (DMs) of fast radio bursts (FRBs), making DMs a promising probe of cosmology and the spatial di…
Pinning Down the Geometry of the Type Ic Broad-Line Supernova 2026gzf
Xudong Wen, Yi Yang, Jing Lu +11
Type Ic broad-line supernovae (SNe Ic-BL) are often associated with energetic explosions that display a prompt outburst of high-energy emission. Since their progenitor lost the H a…
Searching for Gamma Ray Bursts associated with CHIME Fast Radio bursts
Yi-Fang Liang, Ye Li, Bao Wang +3
Fast radio bursts (FRBs) and gamma-ray bursts (GRBs) are both linked to compact-object activity, yet their possible connection remains unclear. Here we perform a systematic search…
AT 2024wpp: the most luminous fast-evolving optical transient linked to the merger explosion of a black-hole binary
Jialian Liu, Bao Wang, Xiaofeng Wang +48
Fast blue optical transients (FBOTs) represent one of the most exotic astrophysical transients, exhibiting unusually strong emission across X-ray, optical, and radio wavelengths. T…
