The Absolute Radiometer for Cosmology, Astrophsyics, and Diffuse Emission
(ARCADE) looks back to the dawn of the Universe to observe the transition
out of the "cosmic dark ages" as the first stars ignite in nuclear fusion
and the Universe begins to resemble its current form. It consists of
a set of 7 precision radiometers, cooled to nearly absolute zero, and
carried to an altitude of over 35 km (21 miles) by a scientific research
balloon. ARCADE measures the tiny heating of the early Universe by the
first generation of stars and galaxies to form after the Big Bang.
ARCADE will measure the heating of the universe by the first stars and galaxies to form after the Big Bang. It will also search for the signal of relic decays or annilhilation. ARCADE will measure distortions from a blackbody spectrum to limits ARCADE is funded by the National Aeronautics and Space Administration's Science Mission Directorate under the Astronomy and Physics Reseach and Analysis Suborbital Investigation program. We thank Kulesh Software for contributions to the ground software and TeraVicta Technologies for cryogenic MEMS switches. The INPE Divis�o de Astrof�sica provided the sliced horn antennas at 3, 5, and 7 GHz. |
