Description Supergiant Fast X-ray Transients (SFXTs) are a new class of highly variable hard X-ray sources in our galaxy. We propose to perform the first detailed study of the quiescent state of two SFTXs by carrying out XMM observations of IGR J16479-4514 and XTE J1739-302 sources. We will search for pulsations, low-level flaring activity and column density variations, and measure the X-ray spectrum. We will address some key predictions of a recently proposed scenario in which accretion onto the neutron stars of SFXTs is gated by an extremely strong (magnetar-like) magnetic field. SFXTs might thus offer the first opportunity to detect magnetars hosted in binary star systems.

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.
