Abstract | We propose deep EPIC observations of 5 X-ray-emitting rotation-powered pulsarsto obtain detailed view of their light curves and phase-resolved spectra,available so far for only three (not representative) sources. Our sample spans 4decades of energetics, including RPPs with different properties and radio/gamma-ray light curves shapes. Well investigate how RPP emission depends onenergetics, age and geometry. X-ray data will be aligned in phase withcontemporaneous gamma-ray and radio data and fitted, constraining the RPPemission models and geometry in these bands. Studying the multiband, phase-resolved spectra will reveal properties and physics of the pair distribution.Overall, our project will result in a decisive step forward in our understanding of RPP emissions. |

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. |
