EP260321a/SN2026gzf is the first Type Ic-BL supernova with a likely X-ray shock breakout, and such bright breakouts may be rare.
EP251023a is a new extragalactic fast X-ray transient whose optical light curve is interpreted as a rare magnetar-powered internal plateau with derived upper limits on spin period and magnetic field.
EP250304a/SN 2025fhm is presented as a member of an emerging subclass of shocked cocoon-dominated low-luminosity GRB-SNe based on spectral, photometric, and light-curve modeling comparisons to prior events.
Optical imaging and BAGPIPES SED fitting of eight FXTs yields candidate hosts consistent with WD-IMBH TDEs or BNS mergers for most events, with one reclassified as a Galactic flare and evidence for diverse origins.
