cds-question@unistra.frsurveysgalaxiescatalogsinfrared-sourcesinfrared-photometryastronomical-object-identificationWe investigate the nature and properties of far-infrared (FIR) sources in the AKARI Deep Field South (ADF-S). We performed an extensive search for the counterparts to 1000 ADF-S objects brighter than 0.0301Jy in the WIDE-S (90um) AKARI band in the public databases (NED and SIMBAD). We analyzed the properties of the resulting sample: statistics of the identified objects, quality of position determination of the ADF-S sources, their number counts, redshift distribution, and comparison of morphological types, when the corresponding information was available. We performed a simplified analysis of the clustering properties of the ADF-S sources and compiled spectral energy distributions (SEDs) of objects with the highest quality photometry, using three different models. Among 1000 investigated ADF-S sources, 545 were identified with sources at other wavelengths in public databases. From them, 518 are known galaxies and 343 of these were previously known as infra-red sources. Among the remaining sources, there are two quasars and both infrared and radio sources of unknown origin. Among six stellar identifications, at least five are probably the effect of contamination. We measured the redshifts of 48 extragalactic objects and determined the morphological types of 77 galaxies. We present SED models of 47 sources with sufficiently good photometric data. Conclusions: We conclude that the bright FIR point sources observed in the ADF-S are mostly nearby galaxies. Their properties are very similar to the properties of the local population of optically bright galaxies, except for unusually high ratio of peculiar or interacting objects and a lower percentage of elliptical galaxies. The percentage of lenticular galaxies is the same as in the optically bright population, which suggests that galaxies of this type may frequently contain a significant amount of cool dust. It is possible that source confusion plays a significant role in more than 34% of measurements. The SEDs correspond to a variety of galaxy types, from very actively star forming to very quiescent. The AKARI long wavelength bands data have enabled us to determine for the first time that these galaxies are objects with very cool dust.2010A&A...514A..11Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/514/A11CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/297 : AKARI/IRC mid-IR all-sky Survey (ISAS/JAXA, 2010)II/298 : AKARI/FIS All-Sky Survey Point Source Catalogues (ISAS/JAXA, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/514/A11https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/514/A11http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/514/A11https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/514/A11https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/514/A11http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/514/A11GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/514/A11/sample (List of the 545 nearest counterparts of the ADF-S sources from the 6{sigma} catalog (S_90um_>0.0301Jy) (tableA1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/514/A11/sample?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/514/A11/sample?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/514/A11/sample?GETtext/xml+votable180.050000true69.90448-53.013480.0055555555555555565/8486-8487 8496 6/33898-33899 33935 33942-33943 33956-33957 33959 33968-33969 33988 33990 33992-339935.585776613014535e-25 4.514645997451082e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/514/A11?format=asciiInfrareddefaultJ/A+A/514/A11/sampleList of the 545 nearest counterparts of the ADF-S sources from the 6{sigma} catalog (S_90um_>0.0301Jy) (tableA1)recnoRecord number assigned by the VizieR team.
