The Fast X-Ray Transient XRT 210423 and Its Host Galaxy
Abstract Fast X-ray Transients (FXTs) are X-ray flares with durations ranging from a few
hundred seconds to a few hours. Possible origins include the tidal disruption of a white …

Extragalactic fast X-ray transient candidates discovered by Chandra (2014–2022)
Context. Extragalactic fast X-ray transients (FXTs) are short flashes of X-ray photons of
unknown origin that last a few minutes to hours. Aims. We extend the previous search for …

Constraints on Relativistic Jets from the Fast X-ray Transient 210423 using Prompt Radio Follow-Up Observations
D Ibrahimzade, R Margutti, JS Bright… - arXiv preprint arXiv …, 2024 - arxiv.org
Fast X-ray Transients (FXTs) are a new observational class of phenomena with no clear
physical origin. This is at least partially a consequence of limited multi-wavelength follow up …
