MRCR-SUMSS Ultra-steep-spectrum (USS) sample

This paper introduces a new program to find high-redshift radio galaxies in the Southern hemisphere through ultra-steep spectrum (USS) selection. We define a sample of 234 USS...本文介绍了一种全新的选源方案，用于通过超陡谱（ultra-steep spectrum，USS）选源法在南半球搜寻高红移射电星系。我们构建了包含234个超陡谱源的样本……
