Galaxy Infall by Interacting with its Environment: a Comprehensive Study of 340 Galaxy Clusters

Liyi Gu, Zhonglue Wen, Poshak Gandhi +7

To study systematically the evolution on the angular extents of the galaxy, ICM, and dark matter components in galaxy clusters, we compiled the optical and X-ray properties of a sa…

Abundance Patterns in the Interstellar Medium of Early-type Galaxies Observed with Suzaku

Saori Konami, Kyoko Matsushita, Ryo Nagino +1

We have analyzed 17 early-type galaxies, 13 ellipticals and 4 S0's, observed with Suzaku, and investigated metal abundances (O, Mg, Si, and Fe) and abundance ratios (O/Fe, Mg/Fe, a…

Resonant scattering in the Perseus Cluster: spectral model for constraining gas motions with Astro-H

I. Zhuravleva, E. Churazov, R. Sunyaev +6

X-ray spectra from cores of galaxy clusters can be strongly distorted by resonant scattering of line photons, affecting metal abundance and gas velocity measurements. We introduce…

Probing of the Interactions Between the Hot Plasmas and Galaxies in Clusters from z=0.1 to 0.9

Liyi Gu, Poshak Gandhi, Naohisa Inada +7

Based on optical and X-ray data for a sample of 34 relaxed rich clusters of galaxies with redshifts of 0.1-0.9, we studied relative spatial distributions of the two major baryon co…

High-Resolution X-Ray Spectroscopy of the Galactic Supernova Remnant Puppis A with the XMM-Newton RGS

Satoru Katsuda, Hiroshi Tsunemi, Koji Mori +6

We present high-resolution X-ray spectra of cloud-shock interaction regions in the eastern and northern rims of the Galactic supernova remnant Puppis A, using the Reflection Gratin…

Spatial Distribution of Abundance Patterns in the Starburst Galaxy NGC 3079 Revealed with Chandra and Suzaku

Saori Konami, Kyoko Matsushita, Poshak Gandhi +1

We performed simultaneous spectral analysis of 26.6 ksec of Chandra and 102.3 ksec of Suzaku X-ray data of the starburst galaxy NGC 3079. The spectra are extracted from four region…

Suzaku Metal Abundance Patterns in the Outflow Region of M82 and the Importance of Charge Exchange

Saori Konami, Kyoko Matsushita, Takeshi Go Tsuru +2

We performed spectral analysis of Suzaku data of the galactic disk and outflow regions of the starburst galaxy M82. Thermal modeling of the central disk regions requires at least t…

Abundance Patterns in the Interstellar Medium of the S0 Galaxy NGC 1316 (Fornax A) Revealed with Suzaku

Saori Konami, Kyoko Matsushita, Ryo Nagino +3

The Suzaku X-ray satellite observed the nearby S0 galaxy NGC 1316, a merger remnant aged 3 Gyr. The total good exposure time was 48.7 ksec. The spectra were well represented by a t…

Development of Thick-foil and Fine-pitch GEMs with a Laser Etching Technique

T. Tamagawa, A. Hayato, F. Asami +9

We have produced thick-foil and fine-pitch gas electron multipliers (GEMs) using a laser etching technique. To improve production yield we have employed a new material, Liquid Crys…

Suzaku Observation of the Metallicity in the Interstellar Medium of NGC 4258

Saori Konami, Kosuke Sato, Kyoko Matsushita +7

The Suzaku X-ray satellite observed the nearby spiral galaxy NGC 4258 for a total good exposure time of 100 ks. We present an analysis of the Suzaku XIS data, in which we confirm t…
