cds-question@unistra.frradio-sourcesradio-continuum-emissionThe spectral properties of the inhomogeneities of the microwave background on Planck multi-frequency maps that are distant from the sources of the RCR catalog by the half-width of the power beam pattern of the high-frequency Planck complex (+/-2.5 arcmin), as well as the spectral features of the sources depending on the presence of positive spots near them, are studied. About 830 objects of the catalog were examined for the detection of spots with positive amplitudes near them. The features that indicate the connection of positive peaks on the Planck maps with the nearest radio sources are revealed. First, it is the excess of the number of RCR sources with flat and normal spectra, near which there are spots, over the number of sources with steep spectra. Secondly, the number of spots with positive amplitude on Planck maps that coincide within +/-2.5 arcmin with the coordinates of source-free areas on NVSS, FIRST maps and have the same sizes is on average almost one and a half times less than the number of spots that coincide with RCR objects. It is shown that RCR objects, near which there are no spots, have steeper spectra compared to the spectra of sources, near which spots are detected. The distribution of the spectral indices of spots in the range of 30--217 GHz was close to the distribution of the spectral indices of RCR sources in the range of 100MHz-8.5GHz and their median values almost coincided. This may indicate that the positive fluctuations on the Planck maps detected near RCR objects in the range of 30-217GHz are synchrotron in nature and may be associated with these objects. They can be manifestations of these objects or manifestations of their host galaxies and their environment in the submillimeter range. In the range of 353-857GHz, some of the detected spots can be classified as dusty. The spectra of RCR sources, near which such spots were detected, were steeper than the spectra of RCR objects, near which spots were detected only in the frequency channels 30-217GHz. The steeper the spectrum of the RCR object in the range of 100MHz-8.5GHz, the greater the value of the positive spectral index of the nearest spot in the range of 353-857GHz. The spots, whose two-frequency spectral indices indicate their dusty nature, may be associated with the high dust content in the host galaxies of RCR objects and the processes of star formation in them. It is also possible that the rise in the spectra at high frequencies may be caused by the presence of a signal from cold galactic dust on the frequency maps.2021AstBu..76..109Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/AstBu/76.109CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+, 1998)J/other/AstBu/65.42 : RATAN COLD Refined (RCR) catalogue (Soboleva+, 2010)J/other/AstBu/72.150 : RATAN COLD Reined (RCR) catalogue (Zhelenkova+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/AstBu/76.109https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/AstBu/76.109http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/AstBu/76.109https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/AstBu/76.109https://vizier.iucaa.in/viz-bin/votable?-source=J/other/AstBu/76.109http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/AstBu/76.109GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/AstBu/76.109/table1 (Flux densities of spots on the Planck mission multi-frequency maps near 593 radio sources of the catalogue RCR)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/AstBu/76.109/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/other/AstBu/76.109/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/AstBu/76.109/table1?GETtext/xml+votable180.050000true31.08755.0250.0055555555555555565/2057 6857 7866 6/21-23 25-28 37-39 41-44 48 4116-4118 4121-4122 4133-4135 4137-4138 4160 8213-8215 8217 8220 8233-8235 8240 8256 8320 17877-17878 17881-17884 17894-17895 17900 17904 21887 21972 21974 21977-21980 21989-21991 21993-21995 22207 22229 22233 22245 22250 22292-22294 22297-22300 22309-22310 22313-22316 22336 22400 22998 23001-23003 23013-23015 23017-23019 23024 23253 23257-23259 23269-23271 23273-23275 23317-23318 23321 23323-23324 23333-23335 23337 23339 23360 23573-23575 23577 23579-23580 23589-23590 23593-23595 23600 23616 23680 26067 26069-26070 26073-26075 26085-26086 26089-26090 26092 26096 26303 26326 26329-26332 26340-26342 26345-26347 26389-26391 26393-26396 26403 26405-26406 26409-26410 26416 26496 27093-27094 27097-27098 27100 27109-27111 27113-27115 27343 27349-27350 27353-27355 27364-27366 27369-27370 27372 27376 27413-27414 27417-27420 27433-27436 27456 27520 27669-27671 27673-27676 27685-27687 27689-27690 27692 27712 31210-31211 31423 31446 31449-31452 31461-31462 31468 31472 31509-31511 31513 31525-31527 31529-31530 315321.6300131079766582e-23 5.675559809562688e-22https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/AstBu/76.109?format=asciiRadiodefaultJ/other/AstBu/76.109/table1Flux densities of spots on the Planck mission multi-frequency maps near 593 radio sources of the catalogue RCRrecnoRecord number assigned by the VizieR team.
