Multi-Wavelength Photometric and Polarimetric Observations of the Outburst of 3C 454.3 in Dec. 2009
Mahito Sasada, Makoto Uemura, Yasushi Fukazawa +11
In December 2009, 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…
AKARI observations of ice absorption bands towards edge-on YSOs
Y. Aikawa, D. Kamuro, I. Sakon +9
To investigate the composition and evolution of circumstellar ice around low-mass YSOs, we observed ice absorption bands in the near infrared (NIR) towards eight YSOs ranging from…
Observations of the Near- to Mid-Infrared Unidentified Emission Bands in the Interstellar Medium of the Large Magellanic Cloud
Tamami I. Mori, Itsuki Sakon, Takashi Onaka +3
We present the results of near- to mid-infrared slit spectroscopic observations (2.55--13.4 um) of the diffuse emission toward nine positions in the Large Magellanic Cloud with the…
Characterization and Improvement of the Image Quality of the Data Taken with the Infrared Camera (IRC) Mid-Infrared Channels onboard AKARI
Ko Arimatsu, Takashi Onaka, Itsuki Sakon +7
Mid-infrared images frequently suffer artifacts and extended point spread functions (PSFs). We investigate the characteristics of the artifacts and the PSFs in images obtained with…
Diffraction-limited Subaru imaging of M82: sharp mid-infrared view of the starburst core
P. Gandhi, N. Isobe, M. Birkinshaw +4
We present new imaging at 12.81 and 11.7 microns of the central ~40"x30" (~0.7x0.5 kpc) of the starburst galaxy M82. The observations were carried out with the COMICS mid-infrared…
Far-Infrared Luminous Supernova Remnant Kes 17
Ho-Gyu Lee, Dae-Sik Moon, Bon-Chul Koo +4
We present the results of infrared (IR; 2.5--160 um) observations of the supernova remnant (SNR) Kes 17 based on the data obtained with the AKARI and Spitzer satellites. We first d…
