Title A detailed spectral study of 1E1048.1-5937

Author European Space Agency
Description We propose a follow-up of a short GT observation of
1E1048.1-5937 in which significant spectral variations as a function
of the pulse phase and possible spectral lines were detected.
Significant and relatively broad proton cyclotron features
are predicted by model atmosphere calculations for magnetars.
A detailed phase resolved spectroscopy of this Anomalous
X-ray Pulsar (the one with the largest pulse fraction)
can provide important information to discriminate between
models based on accretion onto isolated neutron stars and those
invoking thermal emission from the surface of a magnetar.

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.
