Molecules in Galaxies. III. The Virgo Cluster
Abstract
Using the 7 m Bell Laboratories antenna, observations of 47 spiral galaxies in the Virgo Cluster were made in the (C-12)O J = 1-0 line; CO emission from 25 of the galaxies was detected at greater than the 3 sigma level. Most of the galaxies were observed at the central position, as well as at four adjacent positions one beam-width away. A method is presented for estimating the total flux of the galaxy using this spatially undersampled map. The total CO emission is found to be correlated with radio continuum emission and 60 + 100 micron band far-infrared, reflecting direct relationships among molecular gas content, CO emission, and massive star formation in these galaxies. However, the total CO flux is only poorly correlated with visual blue luminosity.
