Christopher S. Reynolds, Kazushi Iwasawa

We present an analysis of the long Rossi X-ray Timing Explorer (RXTE) observation of the Seyfert 1 galaxy MCG\Gamma6-30-15, taken in July 1997. We have earlier used the data to place constraints for...

Probing the Disk-jet Connection of the Radio Galaxy 3C120 Observed with Suzaku (2006)

Kataoka, Jun, Reeves, James N., Iwasawa, Kazushi, Markowitz, Alex G., Mushotzky, Richard F., Arimoto, Makoto, ...

Broad line radio galaxies (BLRGs) are a rare type of radio-loud AGN, in which the broad optical permitted emission lines have been detected in addition to the extended jet emission. Here we report on...

The XMM-Newton view of Mrk3 and IXO30 (2005)

Bianchi, Stefano, Miniutti, Giovanni, Fabian, Andrew C., Iwasawa, Kazushi

We present the analysis of the XMM-Newton EPIC pn spectrum of the Seyfert 2 galaxy, Mrk3. We confirm that the source is dominated by a pure Compton reflection component and an iron K$\alpha$ line,...

The circumnuclear X-ray reflectors in NGC 1068 and the Circinus Galaxy (2000)

Bianchi, Stefano, Matt, Giorgio, Iwasawa, Kazushi

The ASCA and BeppoSAX spectra of the Circinus Galaxy and NGC 1068 are analysed and compared with photoionization models based on cloudy. In the case of Circinus, a single, mildly ionized reflector...

NGC 7582: The Prototype Narrow-Line X-ray Galaxy (1998)

Schachter, Jonathan F., Fiore, Fabrizio, Elvis, Martin, Mathur, Smita, Wilson, Andrew S., Morse, Jon A., ...

NGC 7582 is a candidate prototype of the Narrow Line X-ray Galaxies (NLXGs) found in deep X-ray surveys. An ASCA observation shows the hard (> 3 keV) X-ray continuum of NGC 7582 drops 40% in ~6 ks,...
