We studied the star-formation and AGN activity of massive galaxies in the redshift range
Multi-Wavelength Photometric and Polarimetric Observations of the Outburst of 3C 454.3 in 2009 December
Fukazawa, Yasushi; Sakon, Itsuki; Sasada, Mahito +11 more
In 2009 December, the bright blazar 3C 454.3 exhibited a strong outburst in the optical, X-ray, and gamma-ray regions. We performed photometric and polarimetric monitoring of this outburst in the optical and near-infrared bands with TRISPEC and HOWPol attached to the Kanata telescope. We also observed this outburst in the infrared band with AKARI,…
Processing of Polycyclic Aromatic Hydrocarbons in Molecular-Loop Regions near the Galactic Center Revealed by AKARI
Oyabu, Shinki; Onaka, Takashi; Yamagishi, Mitsuyoshi +7 more
We present an AKARI mid-infrared diffuse map of an area of about 4° × 3° near the Galactic center in the 9 µm band. The band intensity is mostly attributed to aromatic hydrocarbon infrared emissions of carbonaceous grains at wavelengths of 6.2, 7,7, 8.6, and 11.3 µm. We detected 9 µm emission structures extending from the Galacti…
Slow-Scan Observations with the Infrared Camera (IRC) aboard AKARI
Oyabu, Shinki; Yamamura, Issei; Takita, Satoshi +6 more
We present the characterization and calibration of the slow-scan observation mode of the Infrared Camera (IRC) aboard AKARI. The IRC Slow-scan observations were operated at the S9W (9µm) and L18W (18µm) bands. We developed a toolkit for data reduction of the IRC Slow-scan observations. We introduced a "self-pointing reconstruction" met…
