We present recent developments of the CAOS "system", an IDL-based Problem Solving Environment (PSE) whose original aim was to define and simulate as...

Se investiga el proceso de captura de galaxias enanas por parte de galaxias gigantes, en presencia de un campo externo causado por materia distribuída y otras...

As available data sets grow in size and complexity, advanced visualization tools enabling their exploration and analysis become more important. In modern...

We present preliminary results of deep echelle spectrophotometry of a sample of HII regions along the disk of the Scd galaxy NGC 300 obtained with the...

We have measured C II and O II recombination lines in several H II regions of low-metallicity dwarf galaxies. These objects show lower C/O ratios than H II...
