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

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.
