breakout or kilonova emissions. Thus, we conclude that a significant fraction of EP-discovered FXTs are associated with events having relativistic jets; either a GRB or a jetted TDE. [7/7 of https://arxiv.org/abs/2504.21096v1]
of so-called `Dark' FXTs, similar to `Dark' GRBs. Additionally, the luminosities of two FXTs were also consistent with jetted tidal disruption events (TDEs). However, their luminosities differ significantly from those of typical supernova shock [6/7 of …
optical counterparts in our observations are fully consistent with the faintest end of the GRB population. However, the non-detection of any associated optical counterpart with a significant fraction of FXTs suggests that EP FXTs are likely a subset [5/…
(>0.5 mag per day). We also find that 11 out of 42 FXTs had shown direct evidence of their association with Gamma-Ray Bursts (GRBs) through significant temporal and spatial overlapping. Furthermore, the luminosities and redshifts of FXTs with confirm [4…
