|Title||Outbursts of radio-quiet AGN|
|Author||Dr Norbert Schartel|
|Description||Recent X-ray observations of the two Seyfert galaxies, GSN 069 and NGC 2617, establish outbursts of radio-quiet AGNs as an unexplored discovery space for AGN physics with an enormous potential to learn. We propose three joint XMM-Newton - NuSTAR observations (start, maximum and 1-e) of the next suited AGN outburst whereas an X-ray-optical-UV light curve will be established with short Swift observations. True AGN outbursts will allow us to trace accretion physics, X-ray spectral complexity connected with dramatic emission-line changes and possibly elusive stellar tidal disruption events probing an even more extreme accretion regime. We will identify outbursts mainly based on Swift, XMM-Newton slew and Gaia observations.|

|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.
