Structural parameters of nearby emission-line galaxies
Miguel Sanchez-Portal, Angeles I Diaz, Elena Terlevich +1
We present the results of an investigation on the main structural properties derived from VRI and Halpha surface photometry of galaxies hosting nuclear emission-line regions (inclu…
Regions of Star Formation: Chemical Issues.(Discussion Session)
Angeles I. Diaz, Mike G. Edmunds, Elena Terlevich
Three are the main questions that were posed to the audience during this discussion session: a) Can galaxy abundances be believed?, b) What progress can we expect soon and from whe…
Nebular diagnostics for young stellar populations: Photon escape versus atmosphere blanketing
Angeles I. Diaz, Marcelo Castellanos
Emission lines in ionized nebulae can provide strong and useful constraints on the properties of both ionizing and non-ionizing stellar populations in regions with star formation,…
Empirical diagnostics of HII regions based on sulphur emission lines
E. Perez-Montero, A. I. Diaz
Spectrophotometry constitutes a unique way to obtain the whole diagnostics (density, temperature, ionic abundances) of ionized gas nebulae, thus providing invaluable information ab…
Stellar Populations in Circumnuclear Star Forming Regions
A. I. Diaz, M. Alvarez-Alvarez, M. Castellanos
We present a study of the stellar populations and gas physical conditions in Circumnuclear Star Forming Regions (CNSFR) based on broad and narrow band photometry and spectrophotome…
On the large escape of ionizing radiation from GEHRs
M. Castellanos, A. I. Diaz, G. Tenorio-Tagle
A thorough analysis of well studied giant HII regions on galactic discs for which we know the ionizing stellar population, the gas metallicity and the Wolf-Rayet population, leads…
