| Abstract | We have recently detected a glitch in the spin of 1E 1207.4-5209, the compactcentral object (CCO) in SNR PKS1209-51/52, and possibly from a second CCO thatwe are monitoring, PSR J0821-4300 in SNR Puppis A. This is entirely unexpectedfor pulsars with a spin-down rates as small as those found for CCOs. Thesedetections supports a recent conjecture that glitches could be triggered by thediffusion of a buried magnetar strength internal field, 10,000 larger than thedipole fields inferred for CCOs. Here, we propose to search for similar timinganomalies from the third known CCO pulsar, PSR J1852+0040 in SNR Kes 79. Adetection will reveal a general property of CCOs with important theoreticalimplications for NS B-field structure and emission mechanisms, andevolution. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
