We present the discovery of a peculiar X-ray transient, EP241021a, by the Einstein Probe (EP) mission, and the results from multiwavelength follow-up observations. The transient wa…
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…
Simultaneous Multiband Photometry of the Early Optical Afterglow of GRB 240825A with Mephisto
Yehao Cheng, Yu Pan, Yuan-Pei Yang +19
Gamma-ray bursts (GRBs) are the most luminous transients in the universe. The interaction of the relativistic jet with the circumburst medium produces an afterglow and generates mu…
