CONTINUUM RADIO EMISSION FROM VIRGO GALAXIES

We present single-antenna measurements of radio emission from 120 galaxies in the Virgo cluster at 2380 MHz using a 2.6 arc min beam (half-power beam width). We also present interferometric measurements at the same frequency for 48 galaxies with < 1 arc sec resolution. We discuss the relative con...

Description
Summary:We present single-antenna measurements of radio emission from 120 galaxies in the Virgo cluster at 2380 MHz using a 2.6 arc min beam (half-power beam width). We also present interferometric measurements at the same frequency for 48 galaxies with < 1 arc sec resolution. We discuss the relative concentration of the radio emission for these galaxies, particularly the emission from the galactic disk compared with that from the nucleus. It is found that the disk emission dominates in most cases. We also find some indications that the flux concentration is greater in elliptical and lenticular galaxies than it is in spirals.
