Study of Spectral Variations in IRAS 18325-5926
 
 

We analyze Suzaku and XMM-Newton observations of the highly variable Seyfert 2, IRAS 18325-5926. The spectra of the source are well modeled by an absorbed power law component and a secondary power law component in the form of a scattered emission from an on-axis highly ionized medium. With the aid of variability studies, we are able to constrain the extent and geometry of the scatterer. And as an aside, we confirm the presence of a broad Iron line feature in the source for all the observations.
