|Title||Connecting the Ephemeris of the Geminga Pulsar to GLAST|
|Author||Prof Jules Halpern|
|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 has been with X-ray observations. Our continuing XMM ephemeris has made possible several ground-based searches for pulsations, from radio to very high energy gamma-rays. This is the final request for our XMM program on Geminga in order to make a precise phase connection with GLAST, which will be launched in 2008 and will continue the ephemeris thereafter. (We thought that this program would be finished in AO6 but the launch of GLAST was delayed, necessitating this additional proposal.)|

|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.
