The angular dimensions of extragalactic radio sources
Abstract
The angular dimensions of compact components of extragalactic radio sources are calculated theoretically on three hypotheses: (a) magnetic field and relativistic particles energy equipartition; (b) equilibrium between synchrotron and Compton losses; (c) radiative lifetime of the same order as the source's light-travel time. Using angular measurements of 73 radio components, divided into two groups (multicomponent and single-component sources), a correcting formulae is derived to reduce the theoretical values to the observed values.
