| Description | Envelope-stripped, core-collapse SNe (i.e. Type Ibc) have 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 continuation of our XMM program, as part of our multi-wavelength effort, to enable progress. The primary goals are: (i) Constrain the pre-SN mass-loss history of the progenitor star by sampling the environment around H-stripped core-collapse SNe. (ii) Constrain the presence of engines driving the explosion of the most energetic SNe Ibc that are NOT observationally associated with GRBs. |

| 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. |
