Optically Thick Giant H II Regions with Decreasing Density Gradients in three Barred Galaxies

Abstract

Franco, García-Barreto, & de la Fuente (2000, hereinafter FGF00) have re-analyzed the radio continuum emission at 2, 6 and 20 cm from the circumnuclear regions of the barred galaxies NGC 1022, 1326 and 4314. The angular resolution of the observations is approximately 3.7 arcsec , roughly equiva-lent to 200 parsecs. Here we summarize the results discussed in FGF00
