cds-question@unistra.fractive-galactic-nucleiradio-galaxiesgalaxiescatalogsinfrared-sourcesradio-continuum-emissionWe present a study of the radio continuum properties of two luminous/ultraluminous infrared galaxy samples: the OH megamaser (OHM) sample (74 objects) and the control sample (128 objects) without detected maser emission. We carried out pilot observations for 140 objects with the radio telescope RATAN-600 at 1.2, 2.3, 4.7, 8.2, 11.2, and 22.3GHz in 2019-2021. The OHM sample has two times more flat-spectrum sources (32 per cent) than the control sample. Steep radio spectra prevail in both samples. The median spectral index at 4.7GHz {alpha}_4.7_=-0.59 for the OHM sample, and {alpha}_4.7_=-0.71 for the non-OHM galaxies. We confirm a tight correlation of the far-infrared (FIR) and radio luminosities for the OHM sample. We found correlations between isotropic OH line luminosity L_OH_ and the spectral index {alpha}_4.7_ ({rho}=0.26, p-val.=0.04) and between L_OH_ and radio luminosity P_1.4_ ({rho}=0.35, p-val.=0.005). Reviewing subsamples of masers powered by active galactic nuclei (AGNs) and star formation revealed insignificant differences for their FIR and radio properties. None the less, AGN-powered galaxies exhibit larger scatter in a range of parameters and their standard deviations. The similarities in the radio and FIR properties in the two samples are presumably caused by the presence of a significant amount of AGN sources in both samples (47 and 30 per cent in the OHM and control samples) and/or possibly by the presence of undetected OH emission sources in the control sample.2022MNRAS.510.2495Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/510/2495CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/510/2495https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/510/2495http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/510/2495https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/510/2495https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/510/2495http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/510/2495GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/510/2495/tablea1 (The OHM parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/510/2495/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/510/2495/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/510/2495/tablea1?GETtext/xml+votable180.050000true2.086916740.63202780.005555555555555556Cone search capability for table J/MNRAS/510/2495/tablea2 (The control parameters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/510/2495/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/510/2495/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/510/2495/tablea2?GETtext/xml+votable180.050000true1.161083336.89186110.0055555555555555566/40 388 430 479 624 650 711 718 740 747 755 826 1053 1918 2113 2245 2277 2397 2722 4113 4121 4290 4412 4421 4452 4695 4898 5038 5249 5257 5379 5395 5523 5651 6098 6401 6696 7552 8249 8266 8410 8419 8441 8610 8637 8673 8841 8855 8926 9035 9084 9092 9099 9161 9190 9262 9342 9353 9770 9817 10265 10274 10281 10317 10324 10448 11033 11101 11206 12317 12366 12441 12481 12537 12886 12892 12925 12932 13061 13093 13191 13434 13488 13552 13601 13632 13850 13925 14868 14885-14886 16650 16655 17075 17506 17754 17819 18137 18260 18894-18895 18915-18916 18919 19163 19241 19280 19288 19628 19730 19945 19962 20101 20208 20238 20262 20277 20349 20386 20389 20393 20443 21016 21029 21991 21999-22000 22299 22305 22352 23148 23298 23362 23477 24005 24059 24584 24957 25561 25960 26013 26047 26093 26205 26213 26264 26292 26298 26403 26459 26491 26529 26540 27222 27310 27502 27537 27555 27614 27628 27800 27816 27843 27873 27892 28017 28074 28164 28303 28513 28525 30061 30146 30565 30822 31081 31178 31303 31327 31399 31439 31467 31514 31522 31729 31795 31973 32136 32224 32450 32516 32570 32715 34531 35675 36331 38786 39615 44888 44896 484976.62606957030801e-25 1.4776134636257873e-23https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/510/2495?format=asciiInfraredRadiodefaultJ/MNRAS/510/2495/tablea1The OHM parametersSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
