J/ApJ/317/102       Cancer cluster 1.4GHz continuum sources   (Salpeter+, 1987)

1.4 GHz continuum sources in the Cancer cluster. Salpeter E.E., Dickey J.M. <Astrophys. J. 317, 102 (1987)> =1987ApJ...317..102S (SIMBAD/NED BibCode)
ADC_Keywords: Clusters, galaxy ; Galaxies, radio Keywords: galaxies: clustering - galaxies: structure - radio sources: galaxies Abstract: We report on 1.4GHZ continuum observations for 11 VLA fields, using the D-configuration, which contain the A group of the Cancer Cluster. Sixteen Zwicky spiral galaxies in the Cancer Cluster were detected, but no ellipticals. We corroborate the finding that spiral galaxies with close companions tend to have enhanced radio emission. Over 200 continuum sources beyond the Cancer Cluster are tabulated. The spectral index (relative to 610MHz) is given for many of the sources, including some of the Zwicky galaxies. There is a suggestion for a nonuniform number surface-density distribution of the sources, not correlated with the Cancer Cluster. Possible predictions of such nonuniformities, from assumptions on " super-superclusters," are discussed. File Summary:
