Spectral index properties of milliJansky radio sources

Randall, K E; Hopkins, Andrew M.; Norris, R P; Zinn, P.-C.; Middelberg, E; Mao, M Y; Sharp, Robert


At the faintest radio flux densities (S1.4 < 10mJy), conflicting results have arisen regarding whether there is a flattening of the average spectral index between a low radio frequency (325 or 610MHz) and, for example, 1.4GHz. We present a new catalogue of 843-MHz radio sources in the European Large Area ISO Survey-South 1 field, which contains the sources, their Australia Telescope Large Area Survey (ATLAS) counterparts and the spectral index distribution of the sources as a function of flux...[Show more]
