|Title||Source of Energy and pre-explosion progenitor evolution of Super-luminous SNe|
|Author||Prof Raffaella Margutti|
|Description||We propose an in-depth study of 1 Super-Luminous Supernova (SLSN). SLSN are >10 times more luminous than ordinary SN and represent the deaths of the most massive stars in our Universe. Their extreme luminosity requires exotic explosion mechanisms and sources of energy whose nature is unclear. Here we propose a focused XMM 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) Constrain the energy source of SLSN; (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|

|Mission Description||The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
