cds-question@unistra.frgalaxiescatalogssurveysradio-sourcesquasarsradio-galaxiesThe Planck Catalogue of Compact Sources (PCCS2) is an unbiased census of the millimetre sky at sub-Jansky levels, and thus a valuable resource for studies of galaxy evolution. Nevertheless, its application to extra-galactic studies is hindered by its limited angular resolution of few arcminutes. In order to open the PCCS2 for an in-depth exploitation, understanding their nature is paramount: are they active galactic nuclei, dusty star forming galaxies, proto-clusters, chance alignments? Improving the positional information and angular resolution will also be beneficial in this quest. Here we aim to unveil the PCCS2 sources in the northern hemisphere. We observed the bright end of the 143 and 217GHz PCCS2 at Dec>=-41.2 degrees with the New IRAM KID Arrays 2 camera (NIKA2) at 1.2mm (260GHz) and 2.0mm (150GHz). The sample includes 487 targets. Map making and source extraction have been carried out with the latest version of the NIKA2 data reduction software. NIKA2 detected 54% and 77% of the targets at 1.2 and 2.0mm. More than 95% are point-like sources, five are resolved in two components, and only 4% are extended at the resolution of NIKA2. By cross-matching the NIKA2 catalogue to the NASA Extragalactic Database, the redshift of ~86% of the sources was found, covering the range from z~0 to 3.4, with a median z=0.77. The number density of the 143 GHz PCCS2 is 0.029deg^-2^, in good agreement with model predictions. Roughly 80% of these sources are QSOs or AGN, with a median NIKA2 spectral index alpha=-1.15, typical of non-thermal synchrotron emission. With a positional accuracy smaller than 3.0-arcsec, and an angular resolution of 11.6 and 18.0-arcsec at 1.2 and 2.0mm, respectively, the NIKA2 PCCS2 catalogue is hereby released to the community.2026A&A...708L..12Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/708/L12CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/594/A26 : Second Planck Catalogue of Compact Sources (PCCS2)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/708/L12https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/708/L12http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/708/L12https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/708/L12https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/708/L12http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/708/L12GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/708/L12/nika2pc2 (Catalog of NIKA2 PCCS2 sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/708/L12/nika2pc2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/708/L12/nika2pc2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/708/L12/nika2pc2?GETtext/xml+votable180.050000true317.3652725-41.160439420.0055555555555555566/18 110 180 438 514 700 893 991 1154 1497 1702 2143 2228 2280 2331 2404 2409 2414 2600 2721 2844 2867 2996 3016 3402 4152 4285 4365 4572 4695 4820 4825 4940 5125 5139 5448 5458 5546 5597 5693 5776 5806 6164 6368 6496 6507 6532 6548 6853 6963 6984 6996 7212 7389 7446 7570 7606 7642 7653 7896 7911 7969 8057 8299 8515 8577 8615 8717 8858 9016 9442 9460 9612 9629 9676 9723 10006 10163 10354 10426 10432 10474 10501 10548 11408 11430 11605 11631 11639-11640 11715 12241 12301 12352 12466 12475 12619 13273 13297 13320 13353 13427 13572 13582 13676 13729 14842 14854 15023 15067 15286 15525 15857 15916 16049 16059 16170 16247 16272 16298 16320 16655 16676 16720 16962 17184 17186 17215 17414 17516 17541 17579 17665 17734 17857 17917 17927 18214 18378 18409 18457 18506 18561 18624 18669 18718 18755 18766 18821 19023 19043 19271 19327 19370 19402 19567 19593 19622 20433 20468 20888 21215 21574 21758 21960 21968 21972 22363 22396 22501 22620 22767 22797 22814 22829 22917 22950 22993 23014 23127 23159 23364 23416 23691 23704 23882 24116 24123 24571 24775 25016 25083 25196 25255 25302 25332 25501 25630 25659 25742 25818 26056 26115 26131 26292 26297 26303 26374 26873 26900-26901 26907 27243 27310 27423 27523 27595 27765 28083 28139 28167 28370 28517 28950 29218 29718 29772 30519 30928 31079 31190 31391 31399 31666 31775 31915 32311 34517 34699 35514 35786 40474 40479 40762 43822 44052 44313 44526 44749 44805 44899 46445 46764 46868 47534 47605 48142 48496 48589 48595 48798 48846 48878 48965 490719.475279485540455e-23 1.4378570967568383e-22https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/708/L12?format=asciiRadiodefaultJ/A+A/708/L12/nika2pc2Catalog of NIKA2 PCCS2 sourcesrecnoRecord number assigned by the VizieR team.
