Physical properties of circumnuclear ionising clusters. IV. NGC 1097
Sandra Zamora, Angeles I. DÃaz, Asier Castrillo
The circumnuclear star-forming ring of the barred spiral galaxy NGC 1097 provides a unique laboratory to study star formation under extreme conditions. This work aims to derive the…

Sulphur abundances in star-forming regions from optical emission lines: A new approach based on photoionization models consistent with the direct method
Enrique Pérez-Montero, Borja Pérez-DÃaz, José M. VÃlchez +5
The derivation of sulphur chemical abundances in the gas-phase of star-forming galaxies is explored in this work, using the emission lines produced in these regions in the optical…

Deriving the abundance distribution of HII galaxies using sulphur as tracer: Exploring the high-metallicity end
Marta Gavilán, Ãngeles I. DÃaz, Sandra Zamora
The main objective of this work is to derive the distribution of the the metal content of HII galaxies using sulphur as an abundance tracer. This increases the metallicity range th…
