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…

X-ray Activity of the RS CVn-type Star σ Gem with the First-Year Observations of Einstein Probe

Xuan Mao, Giuseppina Micela, Fabio Favata +3

Context. Stellar flares are energetic events driven by the sudden release of magnetic energy in the stellar atmosphere. Studying these flares is crucial for understanding their imp…

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…

An Intermediate-mass Black Hole Lurking in A Galactic Halo Caught Alive during Outburst

C. -C. Jin, D. -Y. Li, N. Jiang +137

Stellar-mass and supermassive black holes abound in the Universe, whereas intermediate-mass black holes (IMBHs) of ~10^2-10^5 solar masses in between are largely missing observatio…

Einstein Probe discovery of EP240408a: a peculiar X-ray transient with an intermediate timescale

Wenda Zhang, Weimin Yuan, Zhixing Ling +136

We report the discovery of a peculiar X-ray transient, EP240408a, by Einstein Probe (EP) and follow-up studies made with EP, Swift, NICER, GROND, ATCA and other ground-based multi-…

LEIA discovery of the longest-lasting and most energetic stellar X-ray flare ever detected

Xuan Mao, He-Yang Liu, Song Wang +40

The Lobster Eye Imager for Astronomy (LEIA) detected a new X-ray transient on 2022 November 7, identified as a superflare event occurring on a nearby K-type giant star HD 251108. T…

A fast X-ray transient from a weak relativistic jet associated with a type Ic-BL supernova

H. Sun, W. -X. Li, L. -D. Liu +163

Massive stars end their lives as core-collapse supernovae, amongst which some extremes are broad-lined type Ic supernovae from Wolf-Rayet stars associated with long-duration gamma-…

Soft X-ray prompt emission from a high-redshift gamma-ray burst EP240315a

Y. Liu, H. Sun, D. Xu +191

Long gamma-ray bursts (GRBs) are believed to originate from core collapse of massive stars. High-redshift GRBs can probe the star formation and reionization history of the early un…

The fast X-ray transient EP240315a: a z ~ 5 gamma-ray burst in a Lyman continuum leaking galaxy

Andrew J. Levan, Peter G. Jonker, Andrea Saccardi +73

The nature of the minute-to-hour long Fast X-ray Transients (FXTs) localised by telescopes such as Chandra, Swift, and XMM-Newton remains mysterious, with numerous models suggested…
