The Suzaku Observation of NGC 3516: Complex Absorption and the Broad and Narrow Fe K Lines

A. Markowitz, J. N. Reeves, G. Miniutti +10

We present results from a 150 ksec Suzaku observation of the Seyfert 1.5 NGC 3516 in October 2005. The source was in a relatively highly absorbed state. Our best-fit model is consi…

Suzaku wide-band X-ray Spectroscopy of the Seyfert 2 AGN in NGC 4945

Takeshi Itoh, Chris Done, Kazuo Makishima +13

Suzaku observed a nearby Seyfert 2 galaxy NGC4945, which hosts one of the brightest active galactic nuclei above 20 keV. Combining data from the X-ray CCD camera (XIS) and the Hard…

Low/Hard State Spectra of GRO J1655-40 Observed with Suzaku

Hiromitsu Takahashi, Yasushi Fukazawa, Tsunefumi Mizuno +23

The Galactic black-hole binary GRO J165540 was observed with Suzaku on 2005 September 22--23, for a net exposure of 35 ks with the X-ray Imaging Spectrometer (XIS) and 20 ks wit…

Relativistic Iron K Emission and absorption in the Seyfert 1.9 galaxy MCG-5-23-16

V. Braito, J. N. Reeves, G. C. Dewangan +9

We present the results of the simultaneous deep XMM and Chandra observations of the bright Seyfert 1.9 galaxy MCG-5-23-16, which is thought to have one of the best known examples o…

Wide-band spectroscopy of the Compton thick Seyfert 2 galaxy Mrk 3 with Suzaku

Hisamitsu Awaki, Naohisa Anabuki, Yasuchi Fukazawa +15

We obtained a wide-band spectrum of the Compton-thick Seyfert 2 galaxy Mrk 3 with Suzaku. The observed spectrum was clearly resolved into weak, soft power-law emission, a heavily a…

Monitoring the Violent Activity from the Inner Accretion Disk of the Seyfert 1.9 Galaxy NGC 2992 with RXTE

Kendrah D. Murphy, Tahir Yaqoob, Yuichi Terashima

We present the results of a one year monitoring campaign of the Seyfert 1.9 galaxy NGC 2992 with RXTE. Historically, the source has been shown to vary dramatically in 2-10 keV flux…
