| Description | After a 10-year hiatus, Mrk 590 has partially re-ignited, with repeated major X-ray and UV flare-ups captured by Swift monitoring. We wish to seize this rare opportunity to document the onset of AGN activity as it occurs, since this can lead to significant insight on the long-standing issue of how AGNs are triggered and fueled. We will use approved Swift XRT monitoring to trigger up to 4 single-visit NuSTAR observations, of which up to 3 are joint with XMM (or NICER). Together, these data are needed to determine if a standard thin accretion disk is being built up as the AGN turns on (and then characterize this event) or if alternate physics are at play. 1 |

| 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. |
