Scientific paper

We propose to observe with Chandra ACIS-S HETG the Seyfert 1 Galaxy NGC 7213 for 150 ks. The source is without a detectable Compton reflection component, but has a neutral iron line with EW~80 eV, suggesting an origin in Compton-thin matter like the BLR. Ionizer iron emission features have also been revealed. The aim of the proposed observation is twofold: a) to measure in detail the neutral iron line width and check whether it is consistent with that of the optical broad lines. b) to confirm the presence of the two ionized lines. To better compare X-ray and BLR line widths, we propose a coordinated optical spectroscopic observation of NGC 7213 with the CTIO 4-m.
