Abstract | Supergiant Fast X-ray Transients (SFXTs) are a new class of highly variable hardX-ray sources in our galaxy. We propose to perform the first detailed study ofthe quiescent state of two SFTXs by carrying out XMM observations of IGRJ16479-4514 and XTE J1739-302 sources. We will search for pulsations, low-levelflaring activity and column density variations, and measure the X-ray spectrum.We will address some key predictions of a recently proposed scenario in whichaccretion onto the neutron stars of SFXTs is gated by an extremely strong(magnetar-like) magnetic field. SFXTs might thus offer the first opportunity todetect magnetars hosted in binary star systems. |

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. |
