X-ray spectroscopy of NGC 3227: ROSAT and Chandra results
Abstract
We present a 100 ksec Chandra LETGS observation of the Seyfert 1.5 galaxy NGC 3227. NGC 3227 is highly variable in X-rays and shows an unusual combination of optical and X-ray properties. The galaxy is one of the best candidates to harbor a `dusty ionized absorber'. Spectral fits to the LETGS spectrum of NGC 3227 are complemented by an analysis of the long- and short-term variability properties of NGC 3227, including ROSAT HRI data. We conclude with a comparison with other AGN which show multi-wavelength evidence for dusty ionized material in their nuclear regions.
