On behalf of the EHT.s Multiwavelength (MWL) Working Group, we propose a jointcampaign on M87* coordinated in part with EHT: 50 ks XMM-Newton, 4 orbitsHubble, 50 ks NuSTAR. These observations will improve constraints on (1) theSED of M87* and its particle acceleration processes, as well as (2) thevariability of the famous jet across the electromagnetic spectrum.

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.
