Radio variability properties for radio sources [PDF]
Astronomy & Astrophysics, 2006 In this paper, we used the database of the university of Michigan Radio Astronomy Observatory (UMRAO) at three (4.8 GHz, 8.0 GHZ, and 14.5 GHz) radio frequency to analyze the radio light curves by the power spectral analysis method in search of possible periodicity.

An Injection System for the CHIME/FRB Experiment
The Astronomical Journal, 2023 Dedicated surveys searching for fast radio bursts (FRBs) are subject to selection effects that bias the observed population of events. Software injection systems are one method of correcting for these biases by injecting a mock population of synthetic ...

Extended Radio Emission in the Perhipheral Regions of the Shapley Concentration Core
Galaxies, 2017 The Shapley Concentration (SC) is a galaxy supercluster (few tens of degrees) in the Local Universe (<z>∼0.048) which is currently undergoing cluster mergers and group accretion.

Radio Sources in the 2dF Galaxy Redshift Survey I. Radio Source Populations [PDF]
Publications of the Astronomical Society of Australia, 1999 AbstractWe present the first results from a study of the radio continuum properties of galaxies in the 2dF Galaxy Redshift Survey, (2dFGRS) based on thirty 2dF fields covering a total area of about 100 deg2. About 1·5% of galaxies with bJ < 19·4 mag. are detected as radio continuum sources in the NRAO VLA Sky Survey (NVSS). Of these, roughly 40% are

Extragalactic Astrophysics With Next-Generation CMB Experiments
Frontiers in Astronomy and Space Sciences, 2019 Planck, SPT, and ACT surveys have clearly demonstrated that Cosmic Microwave Background (CMB) experiments, while optimized for cosmological measurements, have made important contributions to the field of extragalactic astrophysics in the last decade ...

Multiband Study of Radio Sources of the RCR Catalogue with Virtual Observatory Tools
Open Astronomy, 2012 We present early results of our multiband study of the RATAN Cold Revised (RCR) catalogue obtained from seven cycles of the “Cold” survey carried with the RATAN-600 radio telescope at 7.6 cm in 1980-1999, at the declination of the SS 433 source.

Radio Galaxy Zoo: cosmological alignment of radio sources [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 We study the mutual alignment of radio sources within two surveys, FIRST and TGSS. This is done by producing two position angle catalogues containing the preferential directions of respectively $30\,059$ and $11\,674$ extended sources distributed over more than $7\,000$ and $17\,000$ square degrees. The identification of the sources in the FIRST sample
