Performance of the Imaging Fourier Transform Spectrometer with Photoconductive Detector Arrays: An Application for the AKARI Far-Infrared Instrument
Mitsunobu Kawada, Hidenori Takahashi, Noriko Murakami +10
We have developed an imaging Fourier transform spectrometer (FTS) for space-based far-infrared astronomical observations. The FTS employs a newly developed photoconductive detector…
The Far-Infrared Surveyor (FIS) for AKARI
Mitsunobu Kawada, Hajime Baba, Peter D. Barthel +57
The Far-Infrared Surveyor (FIS) is one of two focal plane instruments on the AKARI satellite. FIS has four photometric bands at 65, 90, 140, and 160 um, and uses two kinds of array…
AKARI infrared imaging of reflection nebulae IC4954 and IC4955
Daisuke Ishihara, Takashi Onaka, Hidehiro Kaneda +26
We present the observations of the reflection nebulae IC4954 and IC4955 region with the Infrared Camera (IRC) and the Far-Infrared Surveyor (FIS) on board the infrared astronomical…
Spatial Distributions of Cold and Warm Interstellar Dust in M101 Resolved with AKARI/Far-Infrared Surveyor (FIS)
T. Suzuki, H. Kaneda, T. Nakagawa +5
The nearby face-on spiral galaxy M101 has been observed with the Far-Infrared Surveyor (FIS) onboard AKARI. The far-infrared four-band images reveal fine spatial structures of M101…
The Infrared Astronomical Mission AKARI
H. Murakami, H. Baba, P. Barthel +90
AKARI, the first Japanese satellite dedicated to infrared astronomy, was launched on 2006 February 21, and started observations in May of the same year. AKARI has a 68.5 cm cooled…
The Far-Infrared Properties of Spatially Resolved AKARI Observations
Woong-Seob Jeong, Takao Nakagawa, Issei Yamamura +29
We present the spatially resolved observations of IRAS sources from the Japanese infrared astronomy satellite AKARI All-Sky Survey during the performance verification (PV) phase of…
AKARI Far-Infrared Source Counts in the Lockman Hole
Shuji Matsuura, Mai Shirahata, Mitsunobu Kawada +8
We report initial results of far-infrared observations of the Lockman hole with Far-Infrared Surveyor (FIS) onboard the AKARI infrared satellite. On the basis of slow scan observat…
Far-infrared distributions in nearby spiral galaxies NGC2841 and NGC2976 observed with AKARI/FIS
H. Kaneda, T. Suzuki, T. Onaka +9
Far-infrared (IR) images of the nearby Sb galaxy NGC2841 and the Sc galaxy NGC2976 at wavelengths of 65, 90, 140, and 160 um have been obtained with the Far-Infrared Surveyor (FIS)…
Far-Infrared [C II] Line Survey Observations of the Galactic Plane
Takao Nakagawa, Yukari Yamashita Yui, Yasuo Doi +5
We present results of our survey observations of the [C II] 158 micron line emission from the Galactic plane using the Balloon-borne Infrared Carbon Explorer (BICE). Our survey cov…
Deficit of Far-Infrared [CII] Line Emission toward the Galactic Center
Takao Nakagawa, Yasuo Doi, Yukari Yamashita Yui +5
We have observed the [CII] 158 micron line emission from the Galactic plane (-10 deg < l < 25 deg, |b| <= 3 deg) with the Balloon-borne Infrared Carbon Explorer (BICE). The observe…
