Abstract | In the largest ever systematic search in soft X-rays for coherent periodicitiesabout 440,000 light curves of sources serendipitously detected by the Swift X-Ray Telescope (XRT) and the Chandra Advanced CCD Imaging Spectrometer (ACIS) wehave discovered so far (the project is still on-going) about 40 new X-raypulsators. In this proposal we ask for XMM-Newton follow-ups for four of them,which either show unusual properties or their properties are suggesting thepresence of an accreting neutron star. The requested observations will allow usto unveil their nature and test magnetic gating accretion scenario towards lowfluxes, a regime which has remained poorly explored so far. |

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. |
