Suzaku reveals X-ray continuum piercing the nuclear absorber in Markarian 231
E. Piconcelli, G. Miniutti, P. Ranalli +3
We report the results from a 2011 Suzaku observation of the nearby low-ionization BAL quasar/ULIRG Markarian 231. These data reveal that the X-ray spectrum has undergone a large va…
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…
LOFT: the Large Observatory For X-ray Timing
M. Feroci, J. W. den Herder, E. Bozzo +245
The LOFT mission concept is one of four candidates selected by ESA for the M3 launch opportunity as Medium Size missions of the Cosmic Vision programme. The launch window is curren…
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…
Long XMM observation of the Narrow-Line Seyfert 1 galaxy IRAS13224-3809: rapid variability, high spin and a soft lag
A. C. Fabian, E. Kara, D. J. Walton +21
Results are presented from a 500ks long XMM-Newton observation of the Narrow-Line Seyfert 1 galaxy IRAS13224-3809. The source is rapidly variable on timescales down to a few 100s.…
The nature of the bright ULX X-2 in NGC3921: a Chandra position and HST candidate counterpart
P. G. Jonker, M. Heida, M. A. P. Torres +6
We report on Chandra observations of the bright ultra-luminous X-ray (ULX) source in NGC3921. Previous XMM observations reported in the literature show the presence of a bright ULX…
