J/A+AS/70/95         Warm IRAS sources. I. AGN candidates (de Grijp+ 1987)

Warm IRAS sources. I. A catalogue of AGN candidates from the point source catalog. de Grijp M.H.K., Miley G.K., Lub J. <Astron. Astrophys. Suppl. Ser. 70, 95 (1987)> =1987A&AS...70...95D
ADC_Keywords: Infrared sources ; Active gal. nuclei Keywords: catalogue - Seyferts - infrared radiation Abstract: We have previously shown that a blue (warm) 60 to 25µm infrared colour provides a powerful parameter for discriminating between AGNs and normal galaxies and that the far-IR spectrum is therefore an efficient tool for finding new AGNs (de Grijp et al., 1985Natur.314..140D) Here we present a list of such AGN candidates based on warm IR sources from the IRAS Point Source Catalogue (PSC, Cat. II/125). Identification data and finding charts are also given. In addition the list of warm IRAS sources is supplemented by a compendium of data from the IRAS PSC on detected sources identified with previously known AGNs whose infrared spectra do not bring them within our colour selection criterion File Summary:

Note to table1: Sources were selected on position (high galactic latitude, not in Magellanic and colour (25 to 60µm spectral index between 1.5 and 0.0). All sources satisfying these criteria are included, even when optical identification indicates them to be non-extragalactic objects.

Note (1): the classification uses the following abbreviations: BL = BL Lac object S1 = Seyfert 1 (including QSO) S2 = Seyfert 2 S3 = LINER H2 = galaxy with nucleus HII-region PN = planetary nebula RN = reflection nebula DN = galactic dark cloud ST = star LH = local H2 region in the galaxy GAL = galaxy EF = empty field M31 = M31 type Note (2): Redshifts from Veron & Veron (1985, See Cat. VII/188), Palumbo et al. (1983, See Cat. VII/99), de Grijp et al. (1986, A&A, in prep.) Note (3): Matches with published catalogues using the same catalogue numbering convention as given by the IRAS Catalogue (See II/125). The non-standard "ZG" acronym stands for Zwicky's catalog of galaxies (see e.g. cat. VII/190)
