TL;DR
FIRBACK is a deep far-infrared survey using ISO's ISOPHOT instrument, providing detailed data reduction, analysis, and initial findings on source counts and redshift estimates, revealing high-redshift galaxy populations.
Contribution
This paper introduces the FIRBACK survey, detailing its data processing methods and presenting initial results on source identification and counts at 175 microns.
Findings
Half of the sources are likely at redshifts > 1
Source counts at 175 microns are consistent with galaxy evolution models
First identification of sources with radio and mid-infrared data
Abstract
FIRBACK is one of the deepest cosmological surveys performed in the far infrared, using ISOPHOT. We describe this survey, its data reduction and analysis. We present the maps of fields at 175 microns. We point out some first results: source identifications with radio and mid infrared, and source counts at 175 microns. These two results suggest that half of the FIRBACK sources are probably at redshifts greater than 1. We also present briefly the large follow-up program.
