| Abstract | The Event Horizon Telescope (EHT) is effectively an Earth-sized, interferometricmm-band telescope array with 20 microarcsec spatial that is conductingground-breaking observations of distant supermassive black hole (SMBH) systemsresolution. These emission size scales are consistent with those inferred fromX-ray and gamma-ray variability, thus our request for joint XMM-Newton/NuSTAR/Chandra/EHT observations of a particularly interesting SMBH, MKN 501. MKN 501belongs to a subclass of systems that may consist of a close pair of binaryblack holes. Along with contemporaneous EHT observations approved for Spring2019, joint XMM-Newton/NuSTAR study of MKN 501 will provide combined broad-bandX-ray spectra and variability, while Chandra can provide arcsecond imaging. |

| 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. |
