EP250207b is not a collapsar fast X-ray transient. Is it due to a compact object merger?

P. G. Jonker, A. J. Levan, Xing Liu +41

Fast X-ray Transients (FXTs) are short-lived extra-galactic X-ray sources. Recent progress through multi-wavelength follow-up of Einstein Probe discovered FXTs has shown that sever…
