A SEARCH FOR HIGH VELOCITY GAS IN REGIONS OF ACTIVE STAR FORMATION

摘要

Hemos realizado una biisqueda de gas a alta velocidad en una muestra de Regiones H II Gigantes Extragalacticas y Galaxias H II. Solo se ha detectado este fenomeno en un niimero limitado de objetos, apareciendo este espacialmente localizado. El objeto rns peculiar de la muestra es NGC 2363, donde la emision detectada en la zona nuclear es asimetrica. Long slit spectra at high S/N of a sample of Giant Extragalactic H II Regions and H II galaxies, show evidence for very high velocity ionized gas. This kind of phenomenon appears to be localized in a limited area within the observed regions. The most peculiar object in the sample is NGC 2363, where the profiles of the emission lines detected in the nuclear zone suggest non-symmetrical motions.
