Radio Sources of the Survey on the Declination of the Pulsar in the Crab Nebula ().

The results of the analysis of 205 brightest sources ( mJy), which were found in the sky survey at the declination of the pulsar in the Crab Nebula, are presented. The survey was conducted at a frequency of 4.7 GHz using a three-beam radiometer complex installed in the focus of the Western Sector of the RATAN-600 radio telescope in 2018–2019. Based on the measurements taken and the data collected in the CATS astrophysical catalogs database, the radio spectra of the objects were constructed. For a quarter of all detected sources, data at frequencies above 4 GHz were obtained for the first time, and for the rest they were supplemented. The variability of radiation sources on the scales of the year, from days to months, has been studied. The greatest change in the radio flux was found in the blazar B2 1324 22. The search for daily variability was carried out for 26 of the brightest sources with an average value of mJy. All sources are identified with objects from optical and infrared catalogs. The radio luminosity was calculated for 112 objects with known redshifts. [ABSTRACT FROM AUTHOR]
