Cosmic Infrared Background ExpeRiment (CIBER)

CIBER is a research rocket designed to characterize near-infrared (IR) background radiation. Data collected from CIBER has an advantage over surface telescopes since it will operate above the Earth's atmosphere.

CIBER has three major components:

1. Imagers: two imagers are used to detect spatial fluctuations in the near-IR Extragalactic Background Light (EBL) caused by reionization,

2. Low-Resolution Spectrometer: This will be used to measure the absolute spectrum of the Extragalactic IR background.

3. Narrow-Band Spectrometer: The spectrometer will determine the absolute brightness of the Zodiacal light.

The Cosmic Infrared Background Experiment (CIBER) is a suite of four instruments designed to study the near infrared (IR) background light from above the Earth's atmosphere. The instrument package comprises two imaging telescopes designed to characterize spatial anisotropy in the extragalactic IR background caused by cosmological structure during the epoch of reionization, a low resolution spectrometer to measure the absolute spectrum of the extragalactic IR background, and a narrow band spectrometer optimized to measure the absolute brightness of the Zodiacal light foreground.
