A Combined X-Ray and Gamma Ray Study of the Seyfert Galaxies NGC 7469 and NGC 3227
Abstract
We propose XTE observations of the Seyfert 1 galaxies NGC 7469 and NGC 3227, to be combined with gamma ray spectra of these AGN obtained with the Compton OSSE instrument. The combined XTE and OSSE data, providing continuous energy coverage from 2 keV to >1 MeV, will be used to test and refine the increasingly complex Seyfert spectral models in this energy range. The known variability of these Seyferts may also give information on the separate emission components in the broadband X-ray spectra, since we expect correlated variability between the intrinsic source X-ray flux and reflected emission. Finally, improved models for Seyfert AGN will provide better constraints on the contribution of Seyferts to the diffuse X-ray background.
