Weak Radio and Bright Early Optical Emission in EP260321a: A Comparative Study with XRO 080109 Reveals the Role of Circumstellar Material Mass
Cui-Yuan Dai, Xiang-Yu Wang, Jian-He Zheng
Shock breakout (SBO) occurs when a radiation-mediated shock wave, formed during a core-collapse supernova (SN) explosion, breaks out from the stellar surface of the progenitor or f…
Einstein Probe discovery of the magnetar EP J223759.5+531421
N. Rea, F. Coti Zelati, A. Borghese +44
We report the discovery and early outburst evolution of the new Galactic magnetar EP J223759.5+531421, detected by the Einstein Probe Wide-field X-ray Telescope on 2026 June 28. Fo…
SN 2025fhm: A central-engine powered Ic-BL supernova associated with X-ray transient EP250304a
Cui-Ying Song, Nan Jiang, Xiaofeng Wang +32
We present X-ray, optical, and radio follow-up observations of EP250304a, an extragalactic fast X-ray transient (EFXT) discovered by the Einstein Probe. Its X-ray light curve exhib…
EP241113a: dissipative photospheric emission from a dirty fireball
Cui-Yuan Dai, Xiang-Yu Wang, Bing Zhang
EP241113a, a soft X-ray transient detected by the Einstein Probe (EP), has an isotropic-equivalent energy () comparable to classical gamma-r…
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…
Discovery of EP J175257.3-351923 as a Candidate Black Hole Low-Mass X-ray Binary
G. L. Huang, Q. C. Zhao, L. Tao +30
We report the discovery of a new X-ray transient, EP J175257.3-351923 (EP250916a), by the Einstein Probe (EP) near the Galactic plane. The outburst lasted for at least 250\,days, r…
EP250302a: violent shell collision in a soft-X-ray-selected GRB-like transient
Shao-Yu Fu, Cui-Yuan Dai, Ai-Ling Wang +57
The Einstein Probe opens a previously unexplored soft X-ray window onto gamma-ray bursts, filling a critical observational gap in the soft X-ray coverage of their prompt emission.…
Constraining the PeV gamma-ray emission zone of Cygnus X-3 with contemporaneous GeV timing and spectral observations
Xing-Fu Zhang, Ruo-Yu Liu, Dmitriy Khangulyan +2
Cygnus X-3 has recently been established as a variable ultra-high-energy(UHE) gamma-ray source with photons detected up to 3.7~PeV. The temporal correlation between its PeV activit…
A two-hump spectrum in the prompt emission of GRB 240825A
Hai-Ming Zhang, Zi-Qi Wang, Cui-Yuan Dai +4
An extra hard spectral component that extends to GeV energies, in additional to the typical sub- MeV Band component, appears in several gamma-ray burst (GRBs) detected by Fermi Lar…
Detection of an Orphan X-ray Flare from a Blazar Candidate EP240709a with Einstein Probe
Mingjun Liu, Yijia Zhang, Yun Wang +49
Blazars are often observed to flare across multiple wavelengths. Orphan flares from blazars have been only detected a few times, providing an opportunity to understand the structur…
On the External Inverse Compton Scattering off the Prompt Emission in GRB 221009A
Cui-Yuan Dai, Jian-He Zheng, Xiao-Hong Zhao +2
The light curve of the TeV emission in GRB 221009A displays a smooth transition from an initial rapid rise to a slower rise and eventually a decay phase. The smooth temporal profil…
Evidence for a compact stellar merger origin for GRB 230307A from Fermi-LAT and multi-wavelength afterglow observations
Cui-Yuan Dai, Chen-Lei Guo, Hai-Ming Zhang +2
GRB 230307A is the second brightest gamma-ray burst (GRB) ever detected over 50 years of observations and has a long duration in the prompt emission. Two galaxies are found to be c…
Constraining the jet composition of GRB 221009A with the prompt TeV emission limit
Cui-Yuan Dai, Xiang-Yu Wang, Ruo-Yu Liu +1
Recent LHAASO observations of the prompt emission phase of the brightest-of-all-time GRB 221009A imposes a stringent limit on the flux ratio between the TeV and MeV emissions, $F_{…

Yi-Yun Huang, Cui-yuan Dai, Hai-Ming Zhang +2
Characteristics of the cascade gamma-ray signal resulting from very-high-energy gamma-ray sources, such as gamma-ray bursts, can be used to constrain the strength and structure of…
