A JWST redshift for the host galaxy of EP250207b of z=3.2: a collapsar origin is viable
Agnes P. C. van Hoof, Peter G. Jonker, Andrew J. Levan +27
We present James Webb Space Telescope (JWST) and Hubble Space Telescope (HST) observations of the field of the fast X-ray transient (FXT) detected by Einstein Probe, EP250207b, to…
M-EPDet: Real-Time Real-Bogus Classification and Transient Candidate Judgement for the EP-WXT Pipeline via Multi-Modal Data
Lang Chen, Yunfei Xu, Zhen Zhang +8
The Wide-field X-ray Telescope (WXT) onboard the Einstein Probe (EP) produces a large post-detection candidate stream in which genuine astrophysical sources coexist with instrument…
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…
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…
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…
{\tt RapidGBM}: An Efficient Tool for Fermi-GBM Visibility Checking and Data Analysis with a Case Study of EP240617a
Yun Wang, Jia Ren, Lu-Yao Jiang +15
We have developed a lightweight tool, {\tt RapidGBM}, featuring a web-based interface and capabilities of rapid calculation of Fermi Gamma-ray Burst Monitor (GBM) visibilities and…
