ABSTRACT
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.

PAPERS
Authors marked in red are (co-)investigators in the proposal

Classification of papers are:
- CLASS 1:   papers that present specific XMM-Newton observations
- CLASS 2: papers that refer to published XMM-Newton results with complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3: further deliveries which resulted from the program and which are made available to the community (e.g. source catalogues, processed images or spectra in public data base)
- CLASS 4: comments and suggestions from PI
