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…
Automated Determination of Stellar Population Parameters in Galaxies Using Active Instance-based Learning
Thamar Solorio, Olac Fuentes, Roberto Terlevich +2
In this work we focus on the determination of the relative distributions of young, intermediate-age and old populations of stars in galaxies. Starting from a grid of theoretical po…
Age determination of the nuclear stellar population of Active Galactic Nuclei using Locally Weighted Regression
Trilce Estrada-Piedra, Juan Pablo Torres-Papaqui, Roberto Terlevich +2
We present a new technique to segregate old and young stellar populations in galactic spectra using machine learning methods. We used an ensemble of classifiers, each classifier in…
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…
Optical and near-IR Spectrophotometry of CNSFRs: Preliminary Results
M. Castellanos, A. I. Diaz, M. Alvarez-Alvarez +1
Preliminary results from spectrophotometric observations of Circumnuclear Star Forming Regions (CNSFRs) in the spiral galaxies NGC 2903, NGC 3351 and NGC 3504 are presented. The an…
Spectrophotometry of massive star forming regions with GTC
M. Castellanos, A. I. Diaz, E. Terlevich
In these latest years, the detection of Wolf-Rayet (WR) stars in Giant HII Regions (GHRs) has yielded several questions about our current understanding of massive stars evolution a…
