Monitoring the Building of the Corona in ESO 253-G003
Abstract
The hot corona is central for our understanding of the X-ray emission of active galactic nuclei (AGN). Beside its importance, in fact, we have very little knowledge about the corona. The last years established a new viewing angle as a few observations allowed to observe the building of a hot corona, especially in the context of tidal disruption events. Unfortunately, this observations had to follow an opportunistic approach which substantially limits their significance. Here we propose a systematic monitoring of the building of a corona in ESO 253-G003. ESO 253-G003 shows a strongly periodic disruption of its X-ray emission every ~114 days and subsequent recovery of its X-ray emitting hot corona within 20 days. This offers a unique opportunity to systematically monitor the raise of a coron
