AKARI Near- to Mid-Infrared Imaging and Spectroscopic Observations of the Small Magellanic Cloud. I Bright Point Source List
Onaka, Takashi; Yamamura, Issei; Matsunaga, Noriyuki +9 more
We carried out near- to mid-infrared imaging and spectroscopic observations of patchy areas in the Small Magellanic Cloud using the Infrared Camera aboard AKARI. Two 100 arcmin² areas were imaged in 3.2, 4.1, 7, 11, 15, and 24µm, and also spectroscopically observed in the wavelength range continuously from 2.5 to 13.4µm. The spectral r…
AKARI Infrared Observations of the Edge-On Spiral Galaxy NGC 3079
Onaka, Takashi; Yamagishi, Mitsuyoshi; Kaneda, Hidehiro +3 more
We present AKARI near- to far-infrared images of the nearby edge-on spiral galaxy NGC 3079 in 10 photometric bands. The spectral energy distribution consists of continuum emission from dust with a single temperature of 28-33 K together with strong mid-infrared emission features from polycyclic aromatic hydrocarbons (PAHs). We derived dust masses o…
Calibration of the AKARI Far-Infrared Imaging Fourier-Transform Spectrometer
Nakagawa, Takao; Shirahata, Mai; Doi, Yasuo +16 more
The Far-Infrared Surveyor (FIS) onboard the AKARI satellite has a spectroscopic capability provided by a Fourier transform spectrometer (FIS-FTS). FIS-FTS is the first space-borne imaging FTS dedicated to far-infrared astronomical observations. We describe the calibration process of the FIS-FTS, and discuss its accuracy and reliability. The calibr…
