Insights Into the High-Energy Gamma-ray Emission of Markarian 501 from Extensive Multifrequency Observations in the Fermi Era
LAT collaboration, A. A. Abdo et al., the MAGIC collaboration +6
We report on the gamma-ray activity of the blazar Mrk 501 during the first 480 days of Fermi operation. We find that the average LAT gamma-ray spectrum of Mrk 501 can be well descr…
Fe-K line probing of material around the AGN central engine with Suzaku
Yasushi Fukazawa, Kazuyoshi Hiragi, Motohiro Mizuno +6
We systematically analyzed the high-quality Suzaku data of 88 Seyfert galaxies. We obtained a clear relation between the absorption column density and the equivalent width of the 6…
Constraints on the Cosmic-Ray Density Gradient beyond the Solar Circle from Fermi gamma-ray Observations of the Third Galactic Quadrant
Fermi LAT Collaboration
We report an analysis of the interstellar -ray emission in the third Galactic quadrant measured by the {Fermi} Large Area Telescope. The window encompassing the Galactic plane f…
Soft Gamma-ray Detector for the ASTRO-H Mission
Hiroyasu Tajima, Roger Blandford, Teruaki Enoto +26
ASTRO-H is the next generation JAXA X-ray satellite, intended to carry instruments with broad energy coverage and exquisite energy resolution. The Soft Gamma-ray Detector (SGD) is…
Gamma-ray Spectral Evolution of NGC1275 Observed with Fermi-LAT
J. Kataoka, L. Stawarz, C. C. Cheung +7
We report on a detailed investigation of the high-energy gamma-ray emission from NGC\,1275, a well-known radio galaxy hosted by a giant elliptical located at the center of the near…
Study of the Large-scale Temperature Structure of the Perseus Cluster with Suzaku
Sho Nishino, Yasushi Fukazawa, Katsuhiro Hayashi +2
We report on a study of the large-scale temperature structure of the Perseus cluster with Suzaku, using the observational data of four pointings of 30' offset regions, together wit…
