Short time-scale X-ray spectral variability in the Seyfert 1 galaxy NGC 3783
D. Costanzo, M. Dadina, C. Vignali +9
We report on the X-ray time resolved spectral analysis of XMM-Newton observations of NGC 3783. The main goal is to detect transient features in the Fe K line complex, in order to s…

Multi-epoch properties of the warm absorber in the Seyfert 1 galaxy NGC 985
J. Ebrero, V. Domcek, G. A. Kriss +1
(Abridged) NGC 985 was observed by XMM-Newton twice in 2015, revealing that the source was coming out from a soft X-ray obscuration event that took place in 2013. These kinds of ev…

Transient obscuration event captured in NGC 3227. I. Continuum model for the broadband spectral energy distribution
M. Mehdipour, G. A. Kriss, J. S. Kaastra +21
From Swift monitoring of a sample of active galactic nuclei (AGN) we found a transient X-ray obscuration event in Seyfert-1 galaxy NGC 3227, and thus triggered our joint XMM-Newton…
