XMM-Newton-discovered Fast X-ray Transients: Host galaxies and limits on contemporaneous detections of optical counterparts
D. Eappachen, P. G. Jonker, J. Quirola-Vásquez +18
Extragalactic fast X-ray transients (FXTs) are a class of soft (0.3-10 keV) X-ray transients lasting a few hundred seconds to several hours. Several progenitor mechanisms have been…
Preparing for Gaia Searches for Optical Counterparts of Gravitational Wave Events during O4
Sumedha Biswas, Zuzanna Kostrzewa-Rutkowska, Peter G. Jonker +9
The discovery of gravitational wave (GW) events and the detection of electromagnetic counterparts from GW170817 has started the era of multimessenger GW astronomy.The field has bee…
Extragalactic FXT Candidates Discovered by Chandra (2014-2022)
J. Quirola-Vásquez, F. E. Bauer, P. G. Jonker +9
Extragalactic fast X-ray transients (FXTs) are short flashes of X-ray photons of unknown origin that last a few minutes to hours. We extend the search for extragalactic FXTs from Q…
The Fast X-ray Transient XRT 210423 and its Host Galaxy
D. Eappachen, P. G. Jonker, A. J. Levan +8
Fast X-ray Transients (FXTs) are X-ray flares with a duration ranging from a few hundred seconds to a few hours. Possible origins include the tidal disruption of a white dwarf by a…
