Interaction effects on galaxy pairs with Gemini/GMOS- II: Oxygen abundance gradients
D. A. Rosa, O. L. Dors, A. C. Krabbe +5
In this paper we derived oxygen abundance gradients from HII regions located in eleven galaxies in eight systems of close pairs. Long-slit spectra in the range 4400-7300A were obta…

Metallicity evolution of AGNs from UV emission-lines based on a new index
Oli L. Dors, Monica V. Cardaci, Guillermo F. Hagele +1
We analyzed the evolution of the metallicity of the gas with the redshift for a sample of AGNs in a very wide redshift range (0<z<4) using ultraviolet emission-lines from the narro…
