Optically thick giant H II regions with decreasing density gradients in Three barred galaxies

摘要

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