Type IIn supernovae (SNe IIn) are a heterogeneous class of supernovae (SNe).Neither their evolutionary status nor the origin of the tremendous mass lossfrom their progenitors are known. Many SNe IIn show characteristics of othertypes of SNe, such as IIn/Ia (SNe 2002ic,2005gj), IIn/Ibc (SN 2001em) andIIn/IIL (SN 1998S), known as ..hybrid. SNe. This adds to the mystery of thispeculiar class of SNe and calls for multiwavelength efforts, which can constrainthe progenitor systems and lead to a wealth of information about the surroundingmedium, ejecta density and structure of the SNe. Having already obtained VLAtime to observe SNe IIn in radio bands, we propose to do XMM Spectroscopy of VLAand/or Swift detected SNe IIn to unravel the very nature of the their environment.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
