New radio-loud high-redshift quasar discovered
European astronomers report the detection of a new powerful radio-loud quasar at a redshift of about 5.32. The newfound object, designated PSO J191.05696+86.43172, turns out to be one of the brightest radio quasars identified at such a high redshift......»»
Build a Passive Radar With Software-Defined Radio
Normally, when it comes to radio-related projects, my home of New York City is a terrible place to be. If we could see and hear radio waves, it would make an EDM rave feel like a sensory deprivation tank. Radio interference plagues the metropolis......»»

LOFAR antennas unveil giant glow of radio emission surrounding cluster of galaxies
A Dutch-Italian-German team of astronomers has observed a huge glow of radio emission around a cluster of thousands of galaxies. They combined data from thousands of LOFAR antennas that were focused for 18 nights on an area the size of four full moon.....»»
Did supermassive black holes collapse directly out of giant clouds of gas? It could depend on magnetic fields
Roughly a half-century ago, astronomers realized that the powerful radio source coming from the center of our galaxy (Sagitarrius A*) was a "monster" black hole. Since then, they have found that supermassive black holes (SMBHs) reside at the center o.....»»

Airport 5G restrictions should be made permanent, says aviation body
Last year saw temporary airport 5G restrictions imposed after safety concerns were voiced over potential interference with radio altimeters on airliners. A body representing the aviation industry has now called for these restrictions to be made perm.....»»
Proposed method for radio-frequency interference mitigation and signal restoration of pulsar signals
Pulsar signals obtained with radio telescopes are extremely weak. Generally, there are two primary difficulties in pulsar signal processing—one is the radio-frequency interference (RFI) mitigation, and the other one is information loss due to the p.....»»
Peculiar giant radio galaxy GRG-J223301+131502 investigated by researchers
An international team of astronomers has conducted radio and optical observations of a peculiar giant radio galaxy known as GRG-J223301+131502. Results of the observational campaign shed more light on the properties of this galaxy and have unveiled i.....»»
Indoor high-precision visible light positioning system using non-line-of-sight method
