ASTRO-H White Paper - AGN Reflection
C. Reynolds, Y. Ueda, H. Awaki +9
X-ray observations provide a powerful tool to probe the central engines of active galactic nuclei (AGN). A hard X-ray continuum is produced from deep within the accretion flow onto…
MAXI investigation into the longterm X-ray variability from the very-high-energy gamma-ray blazar Mrk 421
Naoki Isobe, Ryosuke Sato, Yoshihiro Ueda +10
The archetypical very-high-energy gamma-ray blazar Mrk 421 was monitored for more than 3 years with the Gas Slit Camera onboard Monitor of All Sky X-ray Image (MAXI), and its longt…
Suzaku Observation of the Black Hole Binary 4U 1630--47 in the Very High State
Takafumi Hori, Yoshihiro Ueda, Megumi Shidatsu +7
We report the results from an X-ray and near-infrared observation of the Galactic black hole binary 4U 1630--47 in the very high state, performed with {\it Suzaku} and IRSF around…
MAXI observations of GRBs
Motoko Serino, Takanori Sakamoto, Nobuyuki Kawai +40
Monitor of all-sky image (MAXI) Gas Slit Camera (GSC) detects gamma-ray bursts (GRBs) including the bursts with soft spectra, such as X-ray flashes (XRFs). MAXI/GSC is sensitive to…
