A deeper look at the Seyfert 2 NGC 5643
Abstract
The Compton-thick AGN, NGC 5643, is the first candidate foroutflow-induced star formation in a radio-quiet Seyfert galaxy. Evidenceof resolved emission lines in archival RGS data can be modelled with PIEand CIE plasma, produced in an outflowing wind and star forming regions,respectively. However, these RGS spectra have never been studied in greatdetail. Our RGS simulations show that an exposure of 240 ks is requiredto sufficiently separate and resolve the emission lines, allowing us tocharacterise the components and accurately measure the column density,ionisation state and outflow velocity of the emitting PIE plasma. Theseparameters are essential for measuring the X-ray mass outflow rate,which can significantly influence the host galaxy and AGN coevolution.
