Suzaku X-Ray Imaging and Spectroscopy of Cassiopeia A
Y. Maeda, Y. Uchiyama, A. Bamba +26
Suzaku X-ray observations of a young supernova remnant, Cassiopeia A, were carried out. K-shell transition lines from highly ionized ions of various elements were detected, includi…
Radio-Loud Narrow-Line Seyfert 1 as a New Class of Gamma-Ray AGN
LAT Collaboration, G. Ghisellini, L. Maraschi +1
We report the discovery with Fermi/LAT of gamma-ray emission from three radio-loud narrow-line Seyfert 1 galaxies: PKS 1502+036 (z=0.409), 1H 0323+342 (z=0.061) and PKS 2004-447 (z…
Suzaku Wide Band Analysis of the X-ray Variability of TeV Blazar Mrk 421 in 2006
Masayoshi Ushio, Takaaki Tanaka, Grzegorz Madejski +9
We present the results of X-ray observations of the well-studied TeV blazar Mrk 421 with the Suzaku satellite in 2006 April 28. During the observation, Mrk 421 was undergoing a lar…
Long-term Stability of Non-thermal X-ray Modulation in the Gamma-ray Binary LS 5039
Tetsuichi Kishishita, Takaaki Tanaka, Yasunobu Uchiyama +1
We report on long-term stability of X-ray modulation apparently synchronized with an orbital period of 3.9 days in the gamma-ray binary LS 5039. Recent observations with the Suzaku…
Bright AGN Source List from the First Three Months of the Fermi Large Area Telescope All-Sky Survey
A. A. Abdo
The first three months of sky-survey operation with the Fermi Gamma Ray Space Telescope (Fermi) Large Area Telescope (LAT) reveals 132 bright sources at |b|>10 deg with test statis…
