Suzaku Observations of Local Ultraluminous Infrared Galaxies
Stacy H. Teng, Sylvain Veilleux, Naohisa Anabuki +7
We report the results from our analysis of {\it Suzaku} XIS (0.5-10 keV) and HXD/PIN (15-40 keV) observations of five well-known local ULIRGs: {\em IRAS} F05189-2524, {\em IRAS} F0…
On why the Iron K-shell absorption in AGN is not a signature of the local Warm/Hot Intergalactic Medium
James Reeves, Chris Done, Ken Pounds +3
We present a comparison between the 2001 XMM-Newton and 2005 Suzaku observations of the quasar, PG1211+143 at z=0.0809. Variability is observed in the 7 keV iron K-shell absorption…
Type I ULIRGs: Transition Stage from ULIRGs to QSOs
Nozomu Kawakatu, Naohisa Anabuki, Tohru Nagao +2
We examine whether the ultraluminous infrared galaxies that contain a type I Seyfert nucleus (a type I ULIRG) are in the transition stage from ULIRGs to quasi-stellar objects (QSOs…
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…
