Ice emission and the redshifts of submillimeter sources

Observations at submillimeter wavelengths have revealed a population of sources thought to be at relatively large redshifts. The position of the 850 µm passband on the Rayleigh-Jeans portion of the Planck function leads to a maximum redshift estimate of z ∼4.5 since sources will not retain their redshift independent brightness close to the peak of the… (More)
