WebVariability in the radio and optical wave band as well as moving features detected by VLBI observations are commonly explained in terms of shocks propagating in relativistic collimated flows. These models do not take into account the rapid rotation of plasma near a rotating black hole. We show, however, that both phenomena are related to … Webradio and radar astronomy, study of celestial bodies by examination of the radio-frequency energy they emit or reflect. Radio waves penetrate much of the gas and dust in space, as well as the clouds of planetary atmospheres, and pass through Earth’s atmosphere with little distortion. Radio astronomers can therefore obtain a much clearer picture of stars and …
