Outline of Final Research Achievements

The purpose of this project is to analyze the data obtained by many kinds of telescopes to obtain the Cosmic Infrared Background (CIB). In this project, we analyzed the data obtained by the sounding rocket project CIBER, and we successfully obtained the spectrum of the CIB excess based on our preceding results of the Diffuse Galactic Light spectrum and stellar spectra by CIBER. In addition, we published the result by using the Hubble Space Telescope, NASA's astronomical satellite COBE/DIRBE, and the Japanese space infrared space telescope IRTS. In conclusion, we accomplish the goal of this project by obtaining the results of CIB spectra from many kinds of instruments.
