EP250827b/SN 2025wkm is a new X-ray flash–supernova whose long, soft X-ray burst and double-peaked, plateauing optical light curve are best explained by a magnetar central engine interacting with a low-mass circumstellar shell.

A magnetar model unifies emission phases of supernova-associated fast X-ray transients EP240414a, EP250108a, and GRB 171205A via jet, cocoon, wind, and PWN components.
SN 2026gzf exhibits early circumstellar interaction with 0.02 solar masses of material and decadal pre-explosion variability suggesting enhanced eruptive mass loss.
The paper identifies supernova emission matching a scaled SN 1998bw template in the late-time light curve of EP250302a at z=1.131, with early data constraining the jet Lorentz factor above 25.
EP260321a is identified as the faintest shock breakout X-ray transient associated with broad-lined Ic supernova SN 2026gzf, interpreted as originating from a mildly relativistic weak outflow choked inside the progenitor star.
GRB 260310A/SN 2026fgk is a spectroscopically confirmed Type Ic-BL supernova at z=0.153 with 0.4-0.6 times the luminosity of SN 1998bw, nickel mass 0.4-0.5 solar masses, ejected mass 4-6 solar masses, kinetic energy (3-8) x 10^51 erg, and located at a 15 kpc offset due to the host's extended light p
