Detection of blueshifted emission and absorption and a relativistic Iron line in the X-ray spectrum of ESO 323-G077
E. Jimenez-Bailon, Y. Krongold, S. Bianchi +4
We report on the X-ray observation of the Seyfert 1 ESO323-G077 performed with XMM-Newton. The spectra show a complex spectrum with conspicuous absorption and emission features. Th…
XMM-Newton View of the Multi-Phase Warm Absorber in Seyfert 1 Galaxy NGC985
Yair Krongold, Elena Jimenez-Bailon, Maria Santos-Lleo +6
We present an analysis of an XMM-Newton observation of the Seyfert 1 Galaxy NGC 985. The EPIC spectra present strong residuals to a single power-law model, indicating the presence…
The Seyfert 1 Galaxy Mrk 335 at a very low flux state: mapping the soft X-ray photoionised gas
A. L. Longinotti, A. Nucita, M. Santos-Lleo +1
This paper reports on an XMM-Newton observation of the Seyfert 1 Galaxy Mrk 335 performed as a Target of Opportunity when the source was in an unusually low flux state. The low lev…
X-ray spectral variability in PG1535+547: the changing-look of a 'soft X-ray weak' AGN
L. Ballo, M. Giustini, N. Schartel +5
PG1535+547 is a bright NLS1 galaxy, whose high energy emission shows strong variability in shape and flux. ROSAT data classified it as soft X-ray weak QSO (objects whose X-ray-to-o…
X-ray properties of a sample of polar-scattered Seyfert galaxies
E. Jimenez-Bailon, M. Guainazzi, G. Matt +5
We present the results on an XMM-Newton systematic analysis of a sample of nine Seyfert 1 galaxies. When observed in polarised light, the spectra of the selected sources are simila…
XMM-Newton observation of the deep minimum state of PG 2112+059: A spectrum dominated by reflection from the accretion disk?
N. Schartel, P. M. Rodriguez-Pascual, M. Santos-Lleo +5
We analyse a 75ks XMM-Newton observation of PG 2112+059 performed in November 2005 and compare it with a 15ks XMM-Newton observation taken in May 2003. PG 2112+059 was found in a d…
