Source of Energy and pre-explosion progenitor evolution of Super-luminous Supernovae

Project Details


We propose an in-depth study of 1 Super-Luminous Supernova (SLSN). SLSNe outshine ordinary SNe by a factor 10-100 and represent the deaths of the most massive stars in our Universe. Their extreme luminosity requires exotic explosion mechanisms and/or sources of energy whose nature is unclear. Here we propose a continuation of our successful Chandra program to map their X-ray emission down to unprecedented limits as part of our multi-wavelength effort (UV, optical/NIR, radio, hard X-rays). The final goal is to: (i) Pin down the energy source of SLSNe; (ii) Map the diversity of the pre-explosion evolution of their progenitors. (iii) Constrain their possible association with Gamma-Ray Bursts. Our study opens a new window of investigation on the physics of the most powerful stellar explosions.
