This biases the sample due to the steepening of AGN spectra at high radio frequencies. We improve upon this by selecting 3610 compact AGNs using their angular size information (~<0.15arcsec scale) from the Australia Telescope 20GHz (AT20G) high-angular resolution catalogue. We cross-match these against the Wide-field Infrared Survey Explorer AllWISE catalogue and present a catalogue with 3300 (91 per cent) matches, 91 (3 per cent) rejects, and 219 (6 per cent) non-detections that are excellent high-redshift candidates. Of the matched compact AGNs, 92 per cent exhibit QSO mid-infrared colours (W1-W2>0.5). Therefore, our sample of high frequency compact sources has a very high rate of identification with mid-infrared QSOs. We find counterparts for 88 per cent of 387 compact steep-spectrum (CSS) sources in the AT20G survey, 82+/-5 per cent of which exhibit QSO mid-infrared colours and have moderate redshifts (z_median_=0.82), while those dominated by host galaxy colours in mid-infrared have lower redshifts (z_median_=0.13). The latter classified into late- and early-type galaxies using their mid-infrared colours shows a majority (68+/-4 per cent) have colours characteristic of late-type galaxies. Thus, we find that a larger fraction of these CSS sources are embedded in hosts with higher gas densities than average early-type galaxies. We compare mid-infrared colours of our AGNs against those reported for AGNs primarily selected using non-radio techniques. This shows that mid-infrared SED of high frequency selected compact radio AGN is comparatively less red, possibly due to contributions from their hosts. 2020MNRAS.494..923C https://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/494/923 Catalog Research IsServedBy TAP VizieR generic service IsServedBy Conesearch service related-to J/MNRAS/434/956 : AT20G high-angular-resolution catalogue (Chhetri+, 2013) J/MNRAS/438/796 : Local radio-galaxy population at 20GHz (Sadler+, 2014) J/MNRAS/417/2651 : AT20G-optical catalogue (Mahony+, 2011) II/328 : AllWISE Data Release (Cutri+ 2013) https://cds.unistra.fr/vizier-org/licences_vizier.html https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/494/923 https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/494/923 http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/494/923 https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/494/923 https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/494/923 http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/494/923 GET text/xml+votable https://tapvizier.cds.unistra.fr/TAPVizieR/tap Cone search capability for table J/MNRAS/494/923/table2 (AT20G compact AGNs cross-matched with the AllWISE mid-infrared catalogue) https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/494/923/table2? https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/494/923/table2? http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/494/923/table2?
