Description The 3.82s AXP in the SNR CTB 37B is among the youngest and most energetic magnetars, with a spin-down power up to 7.4E34 erg-s. A recent NuSTAR observation reveals hard X-ray emission above 10 keV. We propose to measure its hard spectrum with sufficient accuracy to apply the Beloborodov e--e+ outflow model and to characterize its >10 keV pulsed emission, to study the emission geometry. We also propose to continue monitoring its spin-down rate, which varies by a factor of 2. The most energetic magnetars are SGRs, and a marked increase in their spin-down torque often precedes an outburst. By analogy with SGR-AXP 1E 1547.0-5408, the magnetar with the largest spin-down power, and most similar to the AXP in CTB 37B, we may be observing the behavior of an SGR before it outburst.

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.
