2016 XMM-Newton Observation of IRAS 13224-3809
Abstract
We present spectral analysis of the latest 1.5ms XMM-Newton observation of the narrow line Seyfert 1 galaxy IRAS 13224-3809, simultaneous with NuSTAR observations, focusing on the characteristics of the spectral shape and the trend of the parameters with the flux level. It shows extreme and rapid variability and a strong relativistic Fe K line signature during the observation. Additionally, we detect flux-dependent Si XIV and S XVI absorption lines in the stacked spectrum and lower flux level spectrum, with an outflow velocity of 0.24c. These ultra-fast outflow features are consistent in velocity and ionization with the previously detected Fe, Ne and O features from this source. Finally, we try to explore the possibility of high density disk reflection in this source by fitting the soft excess with a variable density version of the reflection model xillver.
