Description The Geminga pulsar is unique among gamma-ray pulsars in having a precise and continuous, phase-connected ephemeris from 1973 up to the present. Since the demise of the Compton Gamma-Ray Observatory in June 2000, the only practical method of maintaining Geminga.s ephemeris is with X-ray observations. In a continuation of our previous XMM-Newton proposal, we will ask for short observations approximately once per year until 2007, when GLAST will resume the gamma-ray timing of Geminga. The principal scientific need for a phase-connected ephemeris is to provide an absolute phase reference for ground-based observations, and to monitor for glitch activity, as was seen once by EGRET in 1996-1997.

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.
