Abstract

Observation of the cosmic background radiation in the infrared region is reviewed.

The redshifted light from stars of the first generation forms diffuse cosmic background radiation in the near-infrared region. Measurement of the sky fluctuation at 2.2μm gives a very low upper limit. The rocket observation of the near-infrared diffuse emission reveals isotropic emission which is possibly ascribed to an extra-galactic origin. The observed brightness and fluctuation are not consistent with the standard scenario of the primeval galaxies.

In the far-infrared region, integrated light of dust emission of the distant galaxies forms another cosmic background radiation. IRAS and the Nagoya-Berkeley rocket experiment found a clear correlation between HI column density and far-infrared sky brightness, however, there remains an uncorrelated isotropic emission component. If we ascribe this emission to be extragalactic origin, a fairly big evolution effect is required.

In the submillimeter region, the Nagoya-Berkeley rocket experiment has shown that the submillimeter cosmic background is much brighter than expected from the 2.74K blackbody spectrum. The excess energy corresponds to about 10% of the 2.74K blackbody, which requires the vast energy generation in the early universe.
