| Abstract | Swift J1818.0-1607 is a radio-loud magnetar that went into outburst in 2020March. Its spin period of 1.36 s and its derivative imply a field strength of4e14 G, a very young age ~500 years, and a spin down power of 1e36 erg/s, thelargest by far among all magnetars, rivaling those of rotation-powered pulsars(RPPs). Hence Swift J1818.0-1607 may represent the ultimate link between the twopopulations. The source has not reached quiescence yet. Hence, we propose alate-time monitoring campaign to establish its long-term decay trend, reveal thelate-time surface thermal pulse shape and pulsed fraction, and derive theradio-X-ray pulse offset and compare it to the early stages of the outburst, allcrucial elements to place this unique source within the large family of magnetars and RPPs. |

| 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. |
