We propose a method of searching for radio sources exhibiting the Sunyaev-Zeldovich effect in the multi-frequency emission maps from the Planck mission data using a convolutional neural network. A catalog for recognizing radio sources is compiled usi

The review considers the contribution of the results of measuring fluctuations of relic cosmic microwave background (CMB) radiation to cosmological model and the latest results of observational cosmology. We discussed the basics of the modern cosmolo

Millimeter- and submillimeter-wave maps are used to select potential candidate objects with the Sunyaev–Zeldovich effect in the vicinity of RCR (RATAN Cold Refined) radio sources. The properties of “hot” and “cold” spots in the right-ascens

A new method is proposed for studying the population of distant radio sources. It is based on building the average continuum radio spectrum for objects located within the given redshift interval. In this paper the redshift bin size dz is set equal to

We suggest a method and build a model of radio galaxy distribution over the sphere using data from the WENSS catalogs and standard radio count models by Condon. We calculate the angular power spectrum of the contribution of extended radio galaxies in
