| Description | This proposal aims at catching, for the first time, fast (hour time scale) variability in two RQ AGN simultaneously in X-ray and millimeter wavelength. A NOEMA proposal has been submitted at the last AO (10 Sept. 2020) and we ask in this proposal for 50 ks per object of (strictly simultaneous) XMM time. Hour time-scale variability corresponds to 10-100 gravitational radii light travel time around a supermassive black hole of 10^7 Msun. A correlated variability observed between both wavelengths would be a direct proof that the mm emission in RQ AGN is produced very close to the black hole, in a region consistent with the so-called X-ray hot corona. |

| 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. |
