X-ray Evidence for a Buried Active Galactic Nucleus in UGC 5101
Masatoshi Imanishi, Yuichi Terashima, Naohisa Anabuki +1
We present X-ray observations of the ultraluminous infrared galaxy, UGC 5101, thought to contain a buried active galactic nucleus (AGN) based on observations in other wavebands. We…
The X-ray variability of the Narrow-Line Seyfert 1 galaxy IRAS 13224-3809 from an XMM-Newton observation
L. C. Gallo, Th. Boller, Y. Tanaka +5
We report on the XMM-Newton timing properties of the most X-ray variable, radio-quiet, NLS1 IRAS 13224-3809. IRAS 13224-3809 continues to display the extremely variable behavior th…
XMM-Newton observation of the ULIRG NGC 6240: The physical nature of the complex Fe K line emission
Th. Boller, R. Keil, G. Hasinger +5
We report on an XMM-Newton observation of the ultraluminous infrared galaxy NGC 6240. The 0.3-10 keV spectrum can be successfully modelled with: (i) three collisionally ionized pla…
XMM-Newton spectral properties of the Narrow-Line Seyfert 1 galaxy IRAS 13224--3809
Th. Boller, Y. Tanaka, A. Fabian +5
We report on the first XMM-Newton observation of the highly X-ray variable, radio-quiet, Narrow-Line Seyfert 1 galaxy IRAS 13224-3809 obtained during the guaranteed time programme…
