|Title||Late-time X-ray Behavior of Short GRBs: Implications for Energetics and Rates|

|Description||The distribution of jet angles for short GRBs is critical to constrain because it has direct implications for the true energy scale and event rate, parameters of interest for gravitational wave detections. Our current knowledge of the opening angle distribution comes from X-ray observations >1 day after the burst. We propose XMM TOO observations to monitor a short GRB afterglow and constrain its collimation from the (non)detection of a jet break, to constrain or measure >5-20 deg. A precise calculation of the angle also requires broad-band afterglow observations; with our ongoing radio, optical-NIR short GRB TOO programs, our group is uniquely poised to provide the tightest constraints on these angles. We briefly discuss the published results from our AO-12 program.|

|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.
