Description | eROSITA, successfully launched in mid-2019, will perform multiple all-sky X-ray surveys. Monitoring roughly half a million AGN-quasars, eROSITA will identify rare, accretion ignition-depletion events as they occur. To explore how the X-ray corona and accretion disk respond to a sudden, major change in accretion rate, the identified sources need medium signal to noise XMM-Newton ToO (EPIC+OM) observations to derive meaningful spectral constraints. Thus, we propose 10 ToOs (five with 10 ks -- ignition event; five with 60 ks -- depletion event) each joint with VLT FORS2 imaging and spectroscopy (for each ToO 1 hour) for optical counterpart localization and tracking the Broad Line Region.s responses. |

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. |
