On the far-infrared metallicity diagnostics: applications to high-redshift galaxies

Abstract:

In an earlier paper we modelled the far-infrared emission from a star-forming galaxy using the photoionization code CLOUDY and presented metallicity sensitive diagnostics based on farinfrared fine structure line ratios. Here, we focus on the applicability of the [OIII] 88μm/[N II] 122 μm line ratio as a gas-phase metallicity indicator in high-redshift submillimetre luminous galaxies. The [O III] 88μm/[N II] 122 μm ratio is strongly dependent on the ionization parameter (which is related to ...
