Suzaku observation of the Phoenix Galaxy
G. Matt, S. Bianchi, H. Awaki +5
In recent years, several Seyfert 2 galaxies have been discovered that change state when observed in X-rays a few years apart, switching from Compton-thin to reflection-dominated or…
Detection of Hard X-Rays from the Compton-Thick Seyfert 2 Galaxy NGC 2273 with Suzaku
H. Awaki, Y. Terashima, Y. Higaki +1
We have obtained a broad-band spectrum of the Compton-thick Seyfert 2 galaxy NGC 2273 with Suzaku. The spectrum reveals the first detection of hard X-rays above ~10 keV from NGC 22…
The Suzaku Observation of the Nucleus of the Radio-Loud Active Galaxy Centaurus A: Constraints on Abundances of the Accreting Material
A. Markowitz, T. Takahashi, S. Watanabe +16
A Suzaku observation of the nucleus of the radio-loud AGN Centaurus A in 2005 has yielded a broadband spectrum spanning 0.3 to 250 keV. The net exposure times after screening were:…
A variability study of the Seyfert 2 galaxy NGC 6300 with XMM-Newton
H. Awaki, H. Murakami, K. M. Leighly +3
We present the results of timing analysis of the XMM-Newton observation of the Seyfert 2 galaxy NGC 6300. The hard X-ray spectrum above 2 keV consists of a Compton-thin-absorbed po…
An XMM-Newton Observation of the Seyfert 2 Galaxy NGC 6300. I. The Nucleus
Chiho Matsumoto, Aida Nava, Larry A. Maddox +4
We present results from a half-day observation by XMM-Newton of the nucleus of the nearby Seyfert 2 galaxy NGC 6300. The X-ray spectrum of the nucleus consists of a heavily absorbe…
Spectral Statistics and Luminosity Function of a Hard X-ray Complete Sample of Brightest AGNs
K. Shinozaki, T. Miyaji, Y. Ishisaki +4
We investigated the statistics of the X-ray spectral properties of a complete flux-limited sample of bright AGNs from HEAO-1 all-sky catalogs to provide the bright end constraint o…
