| Description | The nature of the persistent, high-energy gamma-ray sources in the Galactic plane remains a mystery. The most likely scenario is a population of middle-aged pulsars, many of which might be radio quiet like Geminga. We have an ongoing program of X-ray, radio, and optical observations of selected EGRET error circles at intermediate Galactic latitude. For one of these fields, at (l,b)=(106,+3), our complete census of X-ray and radio sources reveals a remarkable association between a radio shell with unique properties, and a compact X-ray source. It may be a pulsar with a wind-blown nebula. An XMM observation will determine whether or not this source has a hard X-ray spectrum like that of other gamma-ray pulsars, and can determine its pulse period, . |

| 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. |
