Description Swift J1818.0-1607 is a radio-loud magnetar that went into outburst in 2020 March. Its spin period of 1.36 s and its derivative imply a field strength of 4e14 G, a very young age virgul500 years, and a spin down power of 1e36 erg-s, the largest by far among all magnetars, rivaling those of rotation-powered pulsars (RPPs). Hence Swift J1818.0-1607 may represent the ultimate link between the two populations. The source has not reached quiescence yet. Hence, we propose a late-time monitoring campaign to establish its long-term decay trend, reveal the late-time surface thermal pulse shape and pulsed fraction, and derive the radio-X-ray pulse offset and compare it to the early stages of the outburst, all crucial elements to place this unique source within the large family of magnetars and RPPs.

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.
