Abstract	The flux relaxations of magnetars post-outburst are of great interest as theypermit detailed studies of magnetars and their environments. One model that canexplain the flux relaxation is crustal cooling. In the model, heat is depositedafter an energetic event in the crust and emitted at the surface. A significantamount of heat can propagate deeper inside, heating the core/crust boundary andchanging the shape of the light curve at late times. Therefore, studying theflux relaxation at late times may provides a new opportunity to study theextreme environment near the core. We propose XMM-Newton observations to studythe late-time flux evolution of two magnetars, SGR 1627-41 and Swift J1822.3-1606 to test the crustal cooling model and infer physical properties of the magnetars.

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.
