Internal kinematics of distant field galaxies - I. Emission linewidths for a complete sample of faint blue galaxies at
We present measurements of the [Oii] emission linewidth for a complete sample of 24 blue field galaxies (21.25<B<22, B-R<1.2) at <z>~0.25, obtained with the AUTOFIB fibre spectrograph on the Anglo-Australian Telescope (AAT). Most emission lines are spectrally resolved, yet all have dispersions sigma_v<100kms^-1. Five of the 24 sample members have [Oii] doublet lines with flux ratios that imply gas densities in excess of 100 cm^-3. The line emission in these galaxies may be dominated by an...[Show more]
