Broadband X-ray emission from 1H0419-577: Complex absorption or Compton reflection?
Abstract
We present here the X-ray study of a Seyfert 1 galaxy 1H0419-577 using new 123 ks Suzaku observation taken during Jan 2010. The AGN shows complex 0.6-50 keV spectrum with excess emission above 10keV. The broadband spectrum can be described with a power law of photon index ~2 modified by either complex absorption or Blurred Compton reflection. We examine the best-fit parameters of both the models and discuss more appropriate physical model.For example, the blackbody temperature from the absorption model is much higher than the expected disk temperature while reflection model shows temperature very close to it. We infer that the disk reflection model describes the broad band spectrum better than absorption.
