PublicationEvidence for high velocity gas in giant H II regions
Spectroscopy of selected areas of the two Giant H II Regions (GHR) NGC 5471 and NGC 604 shows convincing evidence for the existence of ionized gas at high...

PublicationEvolution of Super Star Cluster Winds with Strong Cooling
We study the evolution of super star cluster winds driven by stellar winds and supernova explosions. Time-dependent rates at which mass and energy are deposited...

PublicationEvolved massive stars in giant H II regions: the chemical enrichment prior to SN events.
Massive stars have significant effects on the ambient interstellar medium (ISM) via either strong UV radiation or powerful stellar winds. These winds also...

PublicationExpansive components in H II regions
We study the presence of low intensity high velocity components, which we have termed wing features in the integrated Hα emission line profiles of the H II...

PublicationExploring the effects of high-velocity flows in abundance determinations in H II regions: bidimensional spectroscopy of HH 204 in the Orion nebula
We present results from integral field optical spectroscopy with the Potsdam Multi-Aperture Spectrograph of the Herbig-Haro (HH) object HH 204, with a spatial...
