A Shell Collision Scenario for EP251222b/GRB 251222A: Connecting Prompt Emission and Double-Peaked Afterglow

Run Shi, Di Xiao, Brajesh Kumar +23

GRB 251222A is a long-duration gamma-ray burst at a spectroscopic redshift of . It was detected by the EP as the soft X-ray transient EP251222b before and during the gamma…

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…

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…

EP250827b/SN 2025wkm: An X-ray Flash-Supernova Powered by a Central Engine and Circumstellar Interaction

Gokul P. Srinivasaragavan, Dongyue Li, Xander J. Hall +100

We present the discovery of EP250827b/SN 2025wkm, an X-ray Flash (XRF) discovered by the Einstein Probe (EP), accompanied by a broad-line Type Ic supernova (SN Ic-BL) at $z = 0.119…

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…

Multiwavelength Observations of the Apparently Non-repeating FRB 20250316A

Ye Li, Hui Sun, Lei Qian +72

The physical origin of fast radio bursts (FRBs) remains uncertain. Although multiwavelength observations have been widely conducted, only Galactic FRB~20200428D is associated with…

EP250207b is not a collapsar fast X-ray transient. Is it due to a compact object merger?

P. G. Jonker, A. J. Levan, Xing Liu +41

Fast X-ray Transients (FXTs) are short-lived extra-galactic X-ray sources. Recent progress through multi-wavelength follow-up of Einstein Probe discovered FXTs has shown that sever…

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…

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…

Suzaku Monitoring of the Seyfert 1 Galaxy NGC5548: Warm Absorber Location and its Implication for Cosmic Feedback

Y. Krongold, M. Elvis, M. Andrade-Velazquez +12

(Abridged) We present a two month Suzaku X-ray monitoring of the Seyfert 1 galaxy NGC 5548. The campaign consists of 7 observations. We analyze the response in the opacity of the g…
