| Abstract | We propose 150-ks simultaneous XMM-Newton/LOFAR observations of PSR B0823+26 fordeciphering the mystery of pulsar moding. Synchronous switching in the radio andX-ray emission properties of the old and nearly aligned pulsar PSR B0943+10 wasrecently discovered in simultaneous XMM-Newton/radio observations, whichcontinue to challenge all proposed pulsar emission theories. A similar follow-upcampaign on the moding pulsar PSR B1822-09 did not solve this enigma, morewell-studied systems are needed for comparison. PSR B0823+26 is a fascinatingorthogonal pulsar exhibiting similar mode switching in the radio band, and iscurrently the best candidate for a new campaign. |

| 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. |
