Description Recent XMM-Newton observations of Seyfert galaxies establish outbursts of radio-quiet AGNs as a poorly explored discovery space for AGN physics with an enormous potential to learn: GSN 069 is most likely a high Eddington-ratio true Seyfert 2 galaxy with no broad line region and no X-ray continuum. NGC 1566, HE1136-2304 and NGC 2617 are rare changing look AGNs with the latter possibly showing absorption by in-falling matter. We propose two 80ks simultaneous XMMNewton-NuSTAR observations accompanied by optical spectroscopy of the next suited AGN outburst(s). They will allow tracing accretion physics, spectral complexity connected with dramatic emission-line changes and possibly elusive tidal disruption events probing an even more extreme accretion regime.

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.
