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…
Dramatic changes in the observed velocity of the accretion disk wind in MCG-03-58-007 are revealed by XMM-Newton and NuSTAR
V. Braito, J. N. Reeves, G. Matzeu +6
Past X-ray observations of the nearby Seyfert 2 MCG-03-58-007 revealed the presence of a powerful and highly variable disk wind, where two possible phases outflowing with $v_{\rm o…
The nature of the extreme X-ray variability in the NLS1 1H 0707-495
M. L. Parker, W. N. Alston, L. Härer +11
We examine archival XMM-Newton data on the extremely variable narrow-line Seyfert 1 (NLS1) active galactic nucleus (AGN) 1H 0707-495. We construct fractional excess variance (Fvar)…
The X-ray emission of the Seyfert 2 galaxy MCG-01-24-12
R. Middei, G. A. Matzeu, S. Bianchi +7
We present a detailed X-ray spectral analysis of the nearby Seyfert 2 galaxy MCG-01-24-12 based on a multi-epoch data set. Data have been taken with different X-ray satellites, nam…
