Suzaku Discovery of the Strong Radiative Recombination Continuum of Iron from the Supernova Remnant W49B
Midori Ozawa, Katsuji Koyama, Hiroya Yamaguchi +2
We present a hard X-ray spectrum of unprecedented quality of the Galactic supernova remnant W49B obtained with the Suzaku satellite. The spectrum exhibits an unusual structure cons…
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…
X-ray Spectroscopy of the Core of the Perseus Cluster with Suzaku: Elemental Abundances in the Intracluster Medium
Takayuki Tamura, Y. Maeda, K. Mitsuda +7
The results from Suzaku observations of the central region of the Perseus cluster are presented. Deep exposures with the X-ray Imaging Spectrometer provide high quality X-ray spect…
Identification of New Near-Infrared DIBs in the Orion Nebula
Toru Misawa, Poshak Gandhi, Akira Hida +2
Large organic molecules and carbon clusters are basic building blocks of life, but their existence in the universe has not been confirmed beyond doubt. A number of unidentified abs…
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…
Doppler-Broadened Iron X-ray Lines from Tycho's Supernova Remnant
A. Furuzawa, D. Ueno, A. Hayato +13
We use \suzaku observations to measure the spatial variation of the Fe K line with radius in the \tycho supernova remnant. The Fe line widths show a significant decrease from a…
