SN 2024jlc light curves

Being the closest supernova of this class discovered in recent years and one of the closest ever, represented a rare opportunity to study in detail this type of objects. We performed a multi-wavelength analysis, spanning ten orders of magnitude in frequency, including optical/UV photometry and spectroscopy, soft and hard X-rays, and high-energy gamma-rays.

We characterized the event as a slow-evolving and He-rich supernova, with one of the lowest peak luminosities reported for a super-luminous event M_g_~-19.37mag, and a light curve evolution compatible with both circumstellar interaction and magnetar spin-down models, with noticeable contribution from 56Ni decay. No significant excess was found in the soft and hard X-ray bands, for which we provide upper-limits on the flux.
