| Abstract | We propose XMM-Newton observations of two radio-loud magnetars, XTE J1810-197and Swift J1818.0-1607, which are still recovering from their most-recentoutbursts. XTE J1810-197 is still exhibiting a soft X-ray flux a factor 2 largerthan the nominal value, due to the continued existence of a thermal hot spot.The source is currently displaying unique temporal properties not observedbefore, neither in outburst nor quiescence. On the other hand, SwiftJ1818.0-1607 has decayed by 2 order of magnitude so far solely driven by an areashrinkage, with no sign of any cooling; an expected property of most magnetartheoretical scenarios. Hence, establishing the X-ray evolution of these twosources towards quiescence is crucial for a better understanding of the physical driver of magnetar outbursts. |

| 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. |
