The faint radio sky: radio astronomy becomes mainstream

Astronomy and Astrophysics Review, 2016
Radio astronomy has changed. For years it studied relatively rare sources, which emit mostly non-thermal radiation across the entire electromagnetic spectrum, i.e. radio quasars and radio galaxies.

The development of radio astronomy

Astronomische Nachrichten, 2002
Summary: Following the detection of extraterrestrial radio waves in 1932 by Karl Jansky, radio astronomy developed quickly after World War II. It established itself soon as a new branch of astronomy with today's outstanding record in the detection of new phenomena in space. These have been honoured by a number of Nobel prizes.
