Abstract
A large fraction of the sources in flux density limited radio samples have angular sizes < 2 arcsec (and hence projected linear sizes ≤ 10–15 kpc for H 0 = 100 Km/(sec Mpc), and steep (α > 0.5, S∝ ν−α) high frequency spectra (Kapahi, 1981; Peacock and Wall 1982). The proportion of these Compact Steep-spectrum Sources (CSSs) is high (15–30% depending on the selection frequency) amongst distant (z > 0.2) radio sources of high power, both galaxies and quasars. We include in this class the GHz Peaked Spectrum Radio Sources (GPS), sub-kpc objects whose radio spectra are peaked at GHz frequencies (see, e.g., O’Dea et al, 1991).
