Clustering of the Diffuse Infrared Light from the COBE DIRBE Maps. I. C(0) and Limits on the Near-Infrared Background

This paper is devoted to studying the CIB through its correlation properties. We studied the limits on CIB anisotropy in the near IR (1.25, 2.2, and 3.5 um, or

bands respectively. The DIRBE data exhibit a clear color between the various bands with a small dispersion. On the other hand most of the CIB is expected to come from redshifted galaxies and thus should have different color properties. We use this observation to develop a `color subtraction method of linear combinations of maps at two different bands. This method is expected to suppress the dominant fluctuations from foreground stars and nearby galaxies, while not reducing (or perhaps even amplifying) the extragalactic contribution to

Investigation of the zodiacal light from 1 to 240 μm using COBE DIRBE data

The Diffuse InfraRed Background Experiment (DIRBE) onboard the cosmic Background Explorer (COBE) was designed to conduct a search for a cosmic infrared background (CIB), which is expected to be the fossil radiation from the first luminous objects in the universe. The instrument, a ten-band cryogenic absolute photometer and three-band polarimeter with a 0.7 degree(s) beam and a wavelength range from 1 - 240 micrometers , scans the sky redundantly and samples half the sky each day. During the ten month lifetime of the cryogen, the instrument achieved a nominal sensitivity on the sky of 10-9 W/m2/sr at most wavelengths, or approximately 1% of the natural background at wavelengths where the sky is very luminous. The short wavelength bands from 1 - 5 micrometers continue to operate after exhaustion of the cryogen, although at reduced sensitivity. In this paper, we review the design, testing, and in-flight performance of the DIRBE.
