AKARI IRC 2.5-5 um Spectroscopy of Infrared Galaxies over a Wide Luminosity Range
Kohei Ichikawa, Masatoshi Imanishi, Yoshihiro Ueda +4
We present the result of a systematic infrared 2.5-5 um spectroscopic study of 22 nearby infrared galaxies over a wide infrared luminosity range (10 < log(L_IR / Lsun) < 13) obtain…
AKARI Infrared Camera Observations of the 3.3 μm PAH feature in Swift/BAT AGNs
Angel Castro, T. Miyaji, M. Shirahata +6
We explore the relationships between the 3.3 μm polycyclic aromatic hydrocarbon (PAH) feature and active galactic nucleus (AGN) properties of a sample of 54 hard X-ray selected bri…
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…
High-z gamma-ray bursts for unraveling the dark ages mission HiZ-GUNDAM
Daisuke Yonetoku, Tatehiro Mihara, Tatsuya Sawano +28
We are now investigating and studying a small satellite mission HiZ-GUNDAM for future observation of gamma-ray bursts (GRBs). The mission concept is to probe "the end of dark ages…
Luminosity and Redshift Dependence of the Covering Factor of AGNs viewed with WISE and SDSS
Yoshiki Toba, Shinki Oyabu, Hideo Matsuhara +10
In this work, we investigate the dependence of the covering factor (CF) of active galactic nuclei (AGNs) (i) on the mid-infrared (MIR) luminosity and (ii) on the redshift. We const…
