| Description | We have made a tentative discovery of pulsations from an X-ray source at the center of the Galactic supernova remnant Kes 79. A pointed ROSAT PSPC observation indicates a coherent period with marginal significance, limited only by counting statistics. We propose an EPIC-pn observation to confirm this detection and to obtain a second epoch pulse measurement to determine its spin-down rate. This will allow critical pulsar parameters to be estimated. If the ROSAT period is not confirmed, the request 2 X 21 ks exposures, separated by a week, are sufficient to search independently for the pulsar period and its derivative. Identifying a pulsar at the center of Kes 79 and characterizing its unusual properties have important consequences for neutron star evolution. |

| 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. |
