Spatial Distributions of Cold and Warm Interstellar Dust in M101 Resolved with AKARI/Far-Infrared Surveyor (FIS)
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, which include global spiral patterns, giant H II regions embedded in outer spiral arms, and a bar-like feature crossing the center. The spectral energy distribution of the whole galaxy shows the presence of the cold...
متن کاملFar-infrared distributions in nearby spiral galaxies NGC2841 and NGC2976 observed with AKARI/FIS
Far-infrared (IR) images of the nearby Sb galaxy NGC 2841 and the Sc galaxy NGC 2976 at wavelengths of 65, 90, 140, and 160 μm have been obtained with the FarInfrared Surveyor (FIS) onboard AKARI. Both galaxies reveal similar morphologies of dust rings. They are, however, significantly different in the dust temperature: a cold (∼ 21 K) ring for NGC 2841 and a warm (∼ 30 K) ring for NGC 2976, wh...
متن کاملDetection of CFIRB with AKARI/FIS Deep Observations
The Cosmic Far-Infrared Background (CFIRB) contains information about the number and distribution of contributing sources and thus gives us an important key to understand the evolution of galaxies. Using a confusion study to set a fundamental limit to the observations, we investigate the potential to explore the CFIRB with AKARI /FIS deep observations. The Far-Infrared Surveyor (FIS) is one of ...
متن کاملMid-infrared all-sky survey with AKARI
AKARI (formerly called ASTRO-F) is the first Japanese astronomical infrared satellite and it is now in a sun-synchronous polar orbit at the altitude of 700 km. One of the major programs of AKARI observations is an all-sky survey in the midto far-infrared spectral region with 6 photometric bands. AKARI has a 685mm telescope, which is cooled down to about 6K by superfluid liquid helium and mechan...
متن کاملThe Far Infrared And
We have repeated our earlier observations of the Infrared and submllllmeter background radiation. While the measured values of the infrared background radiation remain unchanged, we have failed to observe the high flux previously reported for the 0.4 to 1.3 mm range. This indicates that the flux cannot have been galactic or cosmic, but further observations are needed to rule out a solar cycle d...
