| Description | Magnetars are highly magnetized neutron stars that are powered by the decay of their immense magnetic fields and periodically display violent outbursts. Only four of the 23 confirmed magnetars have displayed radio emission and its origin and connection to the X-ray emission is not well understood. Following an outburst prior to its discovery in 2009, the X-ray and radio fluxes and spin-down torque of the radio-emitting magnetar PSR J1622-4950 decayed. Our monitoring with the Parkes radio telescope has revealed that the torque decrease has settled and the radio emission has ceased. We thus believe that PSR J1622-4950 has arrived in quiescence. We propose to observe the magnetar using XMM in order to characterize its quiescent X-ray state. |

| 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. |
