Title: ACIS GRATING SPECTROSCOPY OF SEYFERT GALAXIES

ABSTRACT
The X-ray spectra of Seyfert galaxies can be very complex with combinations of thermal emission from the accretion disk, Compton upscattering of disk photons, Compton reflection continuum, nonthermal jet continuum, ultrasolf component, neutral and ionized absorbers. This study concentrates on high resolution spectroscopy of one bright Seyfert 1 (NGC 3783) and one bright Seyfert 2 (Circinus galaxy). NGC 3783 is a particularly good laboratory for study of the ionized `warm absorbers' in AGNs; numerous absorption edges are expected which will strongly constrain the geometry of material around the AGN. Circinus is expected to show a rich emission line spectrum superposed on a reflection continuum.
