Wide spatial profiles of Fe Kα lines in the Galactic center diffuse X-rays
Abstract
We have surveyed the spatial profile of the Fe Kα lines in the Galactic center diffuse X-rays (GCDX), including the transient region from the GCDX to the Galactic ridge X-ray emission (GRXE) using the Suzaku XIS data. We compared Fe XXV Kα profile with a stellar mass distribution (SMD) model made from near infrared observations. The Fe XXV Kα profile is nicely fitted with the SMD model in the GRXE region, while that in the GCDX region shows about 4-19 times excess over the best-fit SMD model in the GRXE region. Thus Fe XXV Kα in the GCDX is hardly explained by the same origin of the GRXE.
