|Title||Energy and Geometry of Jet-driven Explosions in the Local Universe|
|Author||Dr Raffaella Margutti|
|Description||We propose an in-depth study of a nearby long gamma-ray burst (GRB,z <0.4) with XMM. Our multi-wavelength effort (radio, optical, Swift-XRT and proposed XMM) is designed to extract the true energy and geometry of these explosions, and to reveal the activity of their central engines. This effort allows us to: (i) investigate whether sub-energetic GRBs share the same explosion mechanisms and central engines as ordinary GRBs; (ii) investigate what essential physical property enables only a small fraction of supernovae to harbor a relativistic GRB outflow; (iii) understand if jet-driven explosions are common in all supernovae. These objectives are only possible by expanding the current small sample of nearby 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.
