Radiophysics (also modern writing radio physics [1]) is a branch of physics focused on the theoretical and experimental study of certain kinds of radiation, its emission, propagation and interaction with matter. The term is used in the following major meanings: study of radio waves (the original area of research) study of radiation used in ...

Therefore, the spectrum between these frequencies forms a relatively "quiet" channel in the interstellar radio noise background. Bernard M. Oliver , who coined the term in 1971, theorized that the waterhole would be an obvious band for communication with extraterrestrial intelligence , [ 2 ] hence the name, which is a pun : in English, a ...
The Cavendish Astrophysics Group (formerly the Radio Astronomy Group) is based at the Cavendish Laboratory at the University of Cambridge. The group operates all of the telescopes at the Mullard Radio Astronomy Observatory except for the 32m MERLIN telescope, which is operated by Jodrell Bank .
The National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research (NCRA-TIFR) is a institute for radio astronomy in India. Research activities at NCRA-TIFR are centered on low frequency radio astronomy, with research in a wide range of areas, including solar physics, pulsars, active galactic nuclei, the interstellar medium, supernova remnants, the Galactic Center, nearby ...
