Catching AGN in Deep Minimum States to Unveil Their Core Environment

The deep minimum state of AGNs is characterized by a strongly suppressed or evenabsent primary continuum. As the continuum disappears weak spectral featureslike relativistic iron lines or narrow soft Xray emission lines from ionisedplasmas become highly significant and their parameters can be determined.Therefore deep minimum states offer unique possibilities to investigate indetail the physics of the reprocessed components in AGN, including the immediatevicinity of the supermassive black hole. Applying our experience (several deepminimum observations) we propose 2 triggered 10ks XMM snapshot, one 80ks XMMfollowup simultaneous with one 80ks NuSTAR one 2orbit HST observation of anAGN in deep minimum state. We will identify deep minimum states mainly based on Swift and XMMNewton slews. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
