Query: The Cosmic Infrared Background Experiment   We are developing a rocket-borne instrument (the Cosmic Infrared Background
ExpeRiment, or CIBER) to search for signatures of primordial galaxy formation
in the cosmic near-infrared extra-galactic background. CIBER consists of a
wide-field two-color camera, a low-resolution absolute spectrometer, and a
high-resolution narrow-band imaging spectrometer. The cameras will search for
spatial fluctuations in the background on angular scales from 7 arcseconds to 2
degrees over a range of angular scales poorly covered by previous experiments.
CIBER will determine if the fluctuations reported by the IRTS arise from
first-light galaxies or have a local origin. In a short rocket flight CIBER has
sensitivity to probe fluctuations 100 times fainter than IRTS/DIRBE. By jointly
observing regions of the sky studied by Spitzer and ASTRO-F, CIBER will build a
multi-color view of the near-infrared background, accurately assessing the
contribution of local (z = 1-3) galaxies to the observed background
fluctuations, allowing a deep and comprehensive survey for first-light galaxy
background fluctuations. The low-resolution spectrometer will search for a
redshifted Lyman cutoff feature between 0.8 - 2.0 microns. The high-resolution
spectrometer will trace zodiacal light using the intensity of scattered
Fraunhofer lines, providing an independent measurement of the zodiacal emission
and a new check of DIRBE zodiacal dust models. The combination will
systematically search for the infrared excess background light reported in
near-infrared DIRBE/IRTS data, compared with the small excess reported at
optical wavelengths.
