Abstract

We have proposed to build the Wide Field Infrared Explorer (WIRE), capable of detecting typical starburst galaxies at a redshift of 0.5, ultraluminous infrared galaxies beyond a redshift of 2, and luminous protogalaxies beyond a redshift of 5. This instrument will survey about 100 deg² of high Galactic latitude sky at 12 and 25 micrometers , in passbands where 20% of the luminosity from local starbursts is radiated. WIRE will measure the 12 - 25 micrometers color of the starburst galaxies, which is a powerful statistical luminosity indicator. The distribution of starburst galaxy 12 - 25 micrometers colors as a function of flux density will reveal their evolutionary history and perhaps the presence of protogalaxies at high redshifts. During its four-month mission lifetime, WIRE will gather important data on starburst galaxies and amass a catalog exceeding the size of the IRAS Point Source Catalog. WIRE is specifically designed to detect the maximum number of high-redshift starburst galaxies using an extremely small and simple instrument. The 28 cm aperture Cassegrain telescope has no moving parts and a wide 34 X 34 arcminute field of view.
