A blurred reflection interpretation for the intermediate flux state in Mrk 335
L. C. Gallo, A. C. Fabian, D. Grupe +7
As part of a long term monitoring campaign of Mrk 335, deep XMM-Newton observations catch the narrow-line Seyfert 1 galaxy (NLS1) in a complex, intermediate flux interval as the ac…

The X-ray variability history of Markarian 3
M. Guainazzi, V. La Parola, G. Miniutti +2
We aim at constraining the geometry of the reprocessing matter in the nearby prototypical Seyfert 2 Galaxy Markarian 3 by studying the time evolution of spectral components associa…

A remarkable long-term light curve, and deep, low-state spectroscopy: Swift & XMM-Newton monitoring of the NLS1 galaxy Mkn 335
D. Grupe, S. Komossa, L. C. Gallo +5
The Narrow-line Seyfert 1 galaxy (NLS1) Mkn 335 is remarkable because it has repeatedly shown deep, long X-ray low-states which show pronounced spectral structure. It has become on…
