Suzaku Observation of the Metallicity Distribution in the Elliptical Galaxy NGC 4636 (2009)

Hayashi, Katsuhiro, Fukazawa, Yasushi, Tozuka, Miyako, Nishino, Sho, Matsushita, Kyoko, Takei, Yoh, ...

NGC 4636, an X-ray bright elliptical galaxy, was observed for 70 ks with Suzaku. The low background and good energy resolution of the XIS enable us to estimate the foreground Galactic emission...

Suzaku Observations of Abell 1795: Cluster Emission to R_200 (2009)

Bautz, Marshall W., Miller, Eric D., Sanders, Jeremy S., Arnaud, Keith A., Mushotzky, Richard F., Porter, F. Scott, ...

We report Suzaku observations of the galaxy cluster Abell 1795 that extend to r_200 ~ 2 Mpc, the radius within which the mean cluster mass density is 200 times the cosmic critical density. These...

The Mock LISA Data Challenges: from Challenge 1B to Challenge 3 (2008)

Babak, Stanislav, Baker, John G., Benacquista, Matthew J., Cornish, Neil J., Crowder, Jeff, Larson, Shane L., ...

The Mock LISA Data Challenges are a programme to demonstrate and encourage the development of LISA data-analysis capabilities, tools and techniques. At the time of this workshop, three rounds of...

An overview of the mock LISA data challenges (2007)

Arnaud, Keith A., Babak, Stanislav, Baker, John G., Benacquista, Matthew J., Cornish, Neil J., Cutler, Curt, ...

The LISA International Science Team Working Group on Data Analysis (LIST-WG1B) is sponsoring several rounds of mock data challenges, with the purpose of fostering the development of LISA...

Report on the first round of the Mock LISA Data Challenges (2007)

Arnaud, Keith A., Auger, Gerard, Babak, Stanislav, Baker, John G., Benacquista, Matthew J., Bloomer, Ed, ...

The Mock LISA Data Challenges (MLDCs) have the dual purpose of fostering the development of LISA data analysis tools and capabilities, and demonstrating the technical readiness already achieved by...

An overview of the second round of the Mock LISA Data Challenges (2007)

Search for Oxygen Emission from Warm-Hot Intergalactic Medium around A2218 with Suzaku (2006)

Takei, Yoh, Ohashi, Takaya, Henry, J. Patrick, Mitsuda, Kazuhisa, Fujimoto, Ryuichi, Tamura, Takayuki, ...

We searched for redshifted O emission lines from the possible warm-hot intergalactic medium (WHIM) surrounding the cluster of galaxies A2218 at z=0.1756 using the XIS instrument on Suzaku. This...

A Chandra X-ray Study of Cygnus A - II. The Nucleus (2001)

Young, Andrew J., Wilson, Andrew S., Terashima, Yuichi, Arnaud, Keith A., Smith, David A.

We report Chandra ACIS and quasi-simultaneous RXTE observations of the nearby, powerful radio galaxy Cygnus A, with the present paper focusing on the properties of the active nucleus. In the Chandra...

A Chandra X-ray Study of Cygnus A - III. The Cluster of Galaxies (2001)

Smith, David A., Wilson, Andrew S., Arnaud, Keith A., Terashima, Yuichi, Young, Andrew J.

The results from a recent Chandra ACIS-S study of the cluster surrounding Cygnus A are presented. We have deprojected the X-ray spectra taken from various elliptical shells in order to derive the run...

Central Elemental Abundance Ratios in the Perseus Cluster: Resonant Scattering or SN Ia Enrichment? (2000)

Dupke, Renato A., Arnaud, Keith A.

We have determined elemental abundance ratios in the core of the Perseus cluster for several elements. These ratios indicate a central dominance of SN Ia ejecta similar to that found for A496, A2199...

A dusty X-ray absorber in the Perseus Cluster ? (1998)

Arnaud, Keith A., Mushotzky, Richard F.

We have analyzed 0.35-7.5 keV X-ray spectra of the center of the Perseus cluster collected using the Broad Band X-Ray Telescope (BBXRT) on the Astro-1 mission. These spectra are particularly useful...
