A Search for a keV Signature of Radiatively Decaying Dark Matter with Suzaku XIS Observations of the X-ray Diffuse Background
Norio Sekiya, Noriko Y. Yamasaki, Kazuhisa Mitsuda
We performed the deepest search for an X-ray emission line between 0.5 and 7 keV from non-baryonic dark matter with the Suzaku XIS. Dark matter associated with the Milky Way galaxy…
ASTRO-H White Paper - Clusters of Galaxies and Related Science
T. Kitayama, M. Bautz, M. Markevitch +22
The next generation X-ray observatory ASTRO-H will open up a new dimension in the study of galaxy clusters by achieving for the first time the spectral resolution required to measu…
OI Fluorescent Line Contamination in Soft X-Ray Diffuse Background Obtained with Suzaku/XIS
Norio Sekiya, Noriko Y. Yamasaki, Kazuhisa Mitsuda +1
The quantitative measurement of OVII line intensity is a powerful method for understanding the soft X-ray diffuse background. By systematically analyzing the OVII line intensity in…
Exploring Hot Gas at Junctions of Galaxy Filaments with Suzaku
Ikuyuki Mitsuishi, Hajime Kawahara, Norio Sekiya +3
We performed five pointing observations with Suzaku to search for hot gases associated with the junctions of galaxy filaments where no significant diffuse X-ray sources were detect…
