Abstract | The 3.82s AXP in the SNR CTB 37B is among the youngest and most energeticmagnetars, with a spin-down power up to 7.4E34 erg/s. A recent NuSTARobservation reveals hard X-ray emission above 10 keV. We propose to measure itshard spectrum with sufficient accuracy to apply the Beloborodov e-/e+ outflowmodel and to characterize its >10 keV pulsed emission, to study the emissiongeometry. We also propose to continue monitoring its spin-down rate, whichvaries by a factor of 2. The most energetic magnetars are SGRs, and a markedincrease in their spin-down torque often precedes an outburst. By analogy withSGR/AXP 1E 1547.0-5408, the magnetar with the largest spin-down power, and mostsimilar to the AXP in CTB 37B, we may be observing the behavior of an SGR before it outburst. |

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. |
