| Abstract | After a 10-year break, Mrk 590 is rekindling its nuclear activity with a rise inX-ray flux! We wish to seize this rare opportunity to record, for the firsttime, the onset of AGN activity as it occurs since this can lead to significantinsight on the long-standing issue of how AGNs are triggered and fueled. We askto trigger up to 3 single-visit joint NuSTAR/Swift/XMM observations to determineif a standard thin accretion disk is being built up as the AGN turns on or ifalternate physics are at play. Relatively inexpensive XMM exposures are neededto constrain any intrinsic absorption. The data are also ideal for testing therecent prediction that quasi-periodic eruptions can explain the flux changesseen for Mrk 590. |

| 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. |
