TL;DR: The Infrared Astronomical Satellite (IRAS) as discussed by the authors consists of a spacecraft and a liquid helium cryostat that contains a cooled IR telescope, whose focal plane assembly is cooled to less than 3 K, and contains 62 IR detectors in the survey array.

TL;DR: The Infrared Astronomical Satellite (IRAS) was launched on January 26, 1983 during its 300-day mission, IRAS surveyed over 96 pct of the celestial sphere at four infrared wavelengths, centered approximately at 12, 25, 60, and 100 microns as mentioned in this paper.

TL;DR: In this paper, the overall spectra of the compact active sources are shown to be well represented by continuous-curvature functions such as parabolas, and the spectra are consistent with models involving continuous particle injection (with synchrotron losses) or first-order Fermi acceleration (with escape and synchoretron losses), but not with models using relativistic Maxwellian electron distributions.

TL;DR: A total of 86 galaxies have been detected at 60 μm in the high galactic latitude portion of the IRAS minisurvey as mentioned in this paper, with an infrared to blue luminosity ratio ranging from 50 to 0.5.

TL;DR: The Infrared Astronomical Satellite (IRAS) mission is described in this paper, where an overview of the mission, a description of the satellite and its telescope system, and a discussion about the mission design, requirements, and inflight modifications are given.
