Interstellar dust properties of M51 from AKARI mid-infrared images
Fumi Egusa, Takehiko Wada, Itsuki Sakon +3
Using mid-infrared (MIR) images of four photometric bands of the Infrared Camera (IRC) onboard the AKARI satellite, S7 (7 um), S11 (11 um), L15 (15 um), and L24 (24 um), we investi…
Low-Resolution Spectrum of the Extragalactic Background Light with AKARI InfraRed Camera
Kohji Tsumura, Toshio Matsumoto, Shuji Matsuura +2
The Extragalactic Background Light (EBL) as an integrated light from outside of our Galaxy includes information of the early universe and the Dark Ages. We analyzed the spectral da…
AKARI Infrared Camera Survey of the Large Magellanic Cloud. I. Point Source Catalog
Daisuke Kato, Yoshifusa Ita, Takashi Onaka +10
We present a near- to mid-infrared point source catalog of 5 photometric bands at 3.2, 7, 11, 15 and 24 um for a 10 deg2 area of the Large Magellanic Cloud (LMC) obtained with the…
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…
PAH emission from the dust lane of an elliptical galaxy with the Spitzer IRS
Hidehiro Kaneda, Takashi Onaka, Itsuki Sakon +5
Spitzer and AKARI observations have found that polycyclic aromatic hydrocarbons (PAHs) are present in nearby elliptical galaxies, but their spatial distributions are still unknown.…
Detection of unidentified infrared bands in a Halpha filament in the dwarf galaxy NGC1569 with AKARI
Takashi Onaka, Hiroko Matsumoto, Itsuki Sakon +1
We performed observations of NGC1569 for 6 infrared bands (3.2, 4.1, 7, 11, 15, and 24 micron) with the Infrared Camera (IRC) onboard AKARI. Near- to mid-infrared (2--13 micron) sp…
