KAIST researchers tested optical frequency comb lasers as reference signals for radio astronomy, aiming to synchronize radio telescopes with light-based timing in VLBI observations.

Radio telescopes let you study the universe by collecting faint radio waves from distant objects. To see extremely small ...

The mystery of fast radio bursts (FRBs) from space may be a step closer to being solved. Astronomers studying a repeating signal from a nearby galaxy have detected radiation at the lowest frequency of ...

The low radio frequency sky survey was one of the important research projects at the Raman Research Institute (RRI) during the early 1980s. Its main purpose was to image the radio emission from the ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...
