Suzaku Observations of the cluster of galaxies Abell 2052 (2008)

Tamura, Takayuki, Mitsuda, Kazuhisa, Takei, Yoh, Yamasaki, Noriko Y., ITOH, Akiharu, Hayashida, Kiyoshi, ...

The results from Suzaku XIS observations of the relaxed cluster of galaxies Abell2052 are presented. Offset pointing data are used to estimate the Galactic foreground emission in the direction to the...

Overdensity of X-ray Sources in the Field of Nearby Clusters of Galaxies (2008)

Hudaverdi, Murat, Kunieda, Hideyo, Tanaka, Takeshi, Haba, Yoshito, Furuzawa, Akihiro, Tawara, Yuzuru, ...

Two nearby clusters of galaxies: A194 (z=0.018) and A1060 (z=0.0114) have been analyzed for their X-ray point source properties with XMM-Newton EPIC-PN data. A multi-band source detection technique...

Wide-band spectroscopy of the Compton thick Seyfert 2 galaxy Mrk 3 with Suzaku (2007)

Awaki, Hisamitsu, Anabuki, Naohisa, Fukazawa, Yasuchi, Gallo, Luigi, Ikeda, Shinya, Isobe, Naoki, ...

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 absorbed power-law...

Revealing the High Energy Emission from the Obscured Seyfert Galaxy MCG -5-23-16 with Suzaku (2006)

Reeves, James N., Awaki, Hisamitsu, Dewangan, Gulab C., Fabian, Andy C., Fukazawa, Yasushi, Gallo, Luigi, ...

We report on a 100 ks Suzaku observation of the bright, nearby (z=0.008486) Seyfert 1.9 galaxy MCG -5-23-16. The broad-band (0.4-100 keV) X-ray spectrum allows us to determine the nature of the high...

Suzaku observations of the hard X-ray variability of MCG-6-30-15: the effects of strong gravity around a Kerr black hole (2006)

Miniutti, Giovanni, Fabian, Andrew C., Anabuki, Naohisa, Crummy, Jamie, Fukazawa, Yasushi, Gallo, Luigi, ...

Suzaku has, for the first time, enabled the hard X-ray variability of the Seyfert 1 galaxy MCG-6-30-15 to be measured. The variability in the 14-45 keV band, which is dominated by a strong reflection...

Density Diagnostics of the Hot Plasma in AE Aquarii with XMM-Newton (2004)

Itoh, Kei, Ishida, Manabu, Kunieda, Hideyo

High resolution spectroscopy of AE Aquarii with the XMM-Newton RGS has enabled us to measure the electron number density of the X-ray-emitting hot plasma to be ~1E11/cm**-3 by means of intensity...

X-ray Properties of the Weak Seyfert 1 Nucleus in NGC 4639 (1999)

Ho, Luis C., Ptak, Andrew, Terashima, Yuichi, Kunieda, Hideyo, Serlemitsos, Peter J., Yaqoob, Tahir, ...

We obtained observations of NGC 4639 with ASCA in order to investigate its mildly active Seyfert 1 nucleus at hard X-ray energies. Koratkar et al. (1995) have previously shown that the nucleus is a...

Detection of an iron K Emission Line from the LINER NGC 4579 (1998)

Terashima, Yuichi, Kunieda, Hideyo, Misaki, Kazutami, Mushotzky, Richard F., Ptak, Andrew F., Reichert, Gail A.

We present the results of an ASCA observation of the LINER NGC 4579. A point-like X-ray source is detected at the nucleus with a 2-10 keV luminosity of 1.5x10^41 ergs/s assuming a distance of 16.8...
