The Infrared Astronomical Satellite (IRAS) has detected many galaxies in the infrared (IR), most of which have fairly steep 25μ to 60μ spectra. Many quasars and active galaxies exhibit a significantly flatter spectrum in the infrared. Several studies, for example, DeGrijp et al. (1985) used this characteristic to select a subsample of “warm” objects from the IRAS PSC (1985).
