The discovery of magnetar-like activity from the young rotation-powered pulsar(RPP) in the supernova remnant (SNR) Kes 75 offers a unique opportunity to studythe connection between RPPs and magnetars, their birth and early evolution. PSRJ1846-0258 and its wind nebula also provide a unique window on shockacceleration physics taking place in some of the highest B-fields known innature. We propose a joint NuSTAR/XMM-Newton observation of Kes 75 tocharacterize its hard X-ray emission in a critical energy band and search for aspectral break near virgul10 keV, to help distinguish PWN from magnetar physics. Fora transitionary object, this may indicate the emergence of a buried, magnetarstrength field responsible for powering the rapid spin-down of the pulsar and its unusually energetic PWN.

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.
