Samples were subject to 33-element geochemistry by four-acid digestion and inductively coupled plasma-atomic emission spectroscopy (ICP-AES) to determine concentrations of copper, silver, lead ...

Abstract: The results of deep long-slit optical spectroscopy for a sample of eight 6C radio galaxies at redshift z∼ 1 are presented. Emission-line ratios are derived for many emission lines with ...
