内容記述 | We report new limits on absolute brightness and fluctuations of the cosmic far-infrared background (CFIRB), on the basis of a cosmological survey in the AKARI Deep Field South (ADFS), which is the lowest cirrus density region in the whole sky, and of the cross-calibration measurements of the zodiacal emissions compared with the COBE/DIRBE results. Thanks to AKARI's capability of the absolute measurement, to accurate subtraction of the zodiacal emissions and to the field selection to cover a wide area minimizing the Galactic foreground, we have successfully detected a significant extragalactic component in the total sky brightness and its fluctuations in a wide angular range from ca. 1 arcmin to a few degrees. High angular resolution of AKARI (ca. 30") was also essential for resolving nearby galaxies and for selective extraction of the CFIRB composed of distant galaxies. The measured CFIRB brightness is significantly higher than the predicted brightness from conventional models of galaxy evolution. Power spectrum analysis for the fluctuations shows not only clear shot-noise due to individual galaxies but also a signature of galaxy clustering. Our results provide new constraints on the evolutionary scenario. | |||||
