An Archival Optical Counterpart Search for Extragalactic Fast X-Ray Transients Discovered by Einstein Probe
Run-Duo Liang, Wen-Xiong Li, Liang-Duan Liu +50
Extragalactic fast X-ray transients (eFXTs) represent a rapidly growing class of high-energy phenomena, whose physical origins remain poorly understood. With its wide-field, sensit…
Pan-STARRS follow-up of the gravitational-wave event S250818k and the lightcurve of SN 2025ulz
J. H. Gillanders, M. E. Huber, M. Nicholl +30
Kilonovae are the scientifically rich, but observationally elusive, optical transient phenomena associated with compact binary mergers. Only a handful of events have been discovere…
Search for the Optical Counterpart of Einstein Probe Discovered Fast X-ray Transients from Lulin Observatory
Amar Aryan, Ting-Wan Chen, Sheng Yang +24
The launch of the Einstein Probe (EP) mission has revolutionized the detection and follow-up observations of fast X-ray transients (FXTs) by providing prompt and timely access to t…
Einstein Probe Discovery of EP J182730.0-095633: A New Black Hole X-ray Binary Candidate in Faint Outburst?
Huaqing Cheng, Qingchang Zhao, L. Tao +77
Black hole X-ray binaries (candidates) currently identified in our galaxy are mainly transient sources, with the majority discovered through the detection of their X-ray outbursts.…
EP 250108a/SN 2025kg: Observations of the most nearby Broad-Line Type Ic Supernova following an Einstein Probe Fast X-ray Transient
J. C. Rastinejad, A. J. Levan, P. G. Jonker +66
With a small sample of fast X-ray transients (FXTs) with multi-wavelength counterparts discovered to date, the progenitors of FXTs and their connections to gamma-ray bursts (GRBs)…
