|Title||Young mysterious Type IIn supernovae unveiled through XMM spectroscopy|
|Author||Dr Poonam Chandra|
|Description||Type IIn supernovae (SNe IIn) are a heterogeneous class of supernovae (SNe). Neither their evolutionary status nor the origin of the tremendous mass loss from their progenitors are known. Many SNe IIn show characteristics of other types of SNe, such as IIn-Ia (SNe 2002ic,2005gj), IIn-Ibc (SN 2001em) and IIn-IIL (SN 1998S), known as ..hybrid. SNe. This adds to the mystery of this peculiar class of SNe and calls for multiwavelength efforts, which can constrain the progenitor systems and lead to a wealth of information about the surrounding medium, ejecta density and structure of the SNe. Having already obtained VLA time to observe SNe IIn in radio bands, we propose to do XMM Spectroscopy of VLA and-or Swift detected SNe IIn to unravel the very nature of the their environment.|

|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.
