|Title||Energy and Environment of Hydrogen-poor Core-Collapse SNe|
|Author||Dr Raffaella Margutti|
|Description||Envelope-stripped, core-collapse SNe (i.e. Type Ibc SNe) were recognized as a distinct flavor of core-collapse explosions 25 years ago. SNe Ibc have only recently enjoyed a surge of interest thanks to their association with Gamma-Ray Bursts (GRBs). The peculiar circumstances that enable a small fraction of SNe Ibc to launch a relativistic jet are not understood. Along the same line, the progenitors of SNe Ibc and their relation to those of GRBs have yet to be observationally identified. Here we propose a focused XMM program to enable progress. The primary goals are to (i) populate the gap between ordinary type Ibc SNe and GRBs and (ii) to probe the diversity of the environment of ordinary SNe arising from envelope-stripped progenitors.|

|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.
