| Abstract | eROSITA is performing multiple all-sky X-ray surveys until 2023, and our team issystematically identifying rare accretion ignition/shut-down events -changing-look AGN - as they are transitioning. To track how the X-ray corona,UV/optical accretion disk, and optical broad-line region respond to a sudden,major change in accretion rate, we propose joint ToO observations of XMM-Newton(EPIC+OM) and VLT (FORS2) to obtain at least two observations per triggeredobject (maximum of 4 ignition events and 4 shutdown events). We will constrainthe extent of these drastic flux changes and yield crucial constraints on howthe different structural AGN components respond to dramatic changes of theaccretion rate. |

| 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. |
