We report the results of a visual inspection of images of the Rapid ASKAP Continuum Survey (RACS) in search of extended radio galaxies (ERG) that reach or exceed linear sizes on...

We use the RATAN-600 radio telescope for picking up the most distant objects in the Universe. As a first step, about 100 steep spectrum FRII radio galaxies (SS FRII RG) from the...

Study of high-redshift radio galaxies (HzRGs) can shed light on the active galactic nuclei (AGNs) evolution in massive elliptical galaxies. The vast majority of observed...

Gigahertz-Peaked spectrum (GPS) sources are compact active galactic nuclei, presumably young precursors of bright radio sources. The study of GPS radio properties provides...

We study the synchrotron component of the spectral energy distribution on the sample of 877 blazars using ASDC SED Builder Tool with available broadband data from the...

We study the correlation between the emission from the broad-line region (BLR) and the emission in other wavelength ranges (from radio to x-ray) for the sample of 37 blazars (25...

The results of a comprehensive analysis of continuous radio spectra of a sample of Gigahertz-Peaked Spectrum (GPS) sources are reported. The sources are selected from a...

This catalog groups the 2442 galaxies making up the sample of distant galaxies prepared by the authors published as 3 papers in 2009: radio data (paper I, table1), photometric...

From the cross-correlation of the IRAS FSC catalog with the radio FIRST catalog, 230 infrared galaxies were selected having optical classifications and redshifts from SDSS and...

The dominant source of radio continuum emissions at low frequencies is synchrotron radiation, which originates from star-forming regions in disc galaxies and from powerful jets...

Using stacking of images obtained at different epochs, we studied the variability properties of linear polarization of active galactic nucleus (AGN) jets on parsec-scales. Our...

We analysed the parsec-scale linear polarization properties of 436 active galactic nuclei (AGN) based on 15GHz polarimetric Very Long Baseline Array (VLBA) observations. We...

Giant radio galaxies (GRGs) are radio galaxies that have projected linear extents of more than 700kpc or 1Mpc, depending on definition. We have carried out a careful visual...

We used archival very long baseline interferometry (VLBI) data of active galactic nuclei (AGN) observed from 1.4GHz to 86GHz to measure the angular size of VLBI radio cores in...

We 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...

The Arecibo Ultra-Deep Survey (AUDS) is a blind HI survey aimed at detecting galaxies beyond the local Universe in the 21-cm emission line of neutral hydrogen (HI). The Arecibo...

As the largest radio telescope in the world, the Square Kilometre Array (SKA) will lead the next generation of radio astronomy. The feats of engineering required to construct...

We present the results of new radio observations carried out with the Karl G. Jansky Very Large Array C-configuration at 5.5GHz for a sample of southern narrow-line Seyfert 1...

We present 15-GHz Karl G. Jansky Very Large Array observations of a complete sample of radio galaxies selected at 15.7GHz from the Tenth Cambridge (10C) survey. 67 out of the 95...
