Abstract:
Results are presented from a multifrequency radio continuum survey of
Markarian galaxies (MRKs) and are supplemented by IRAS infrared data
from the Faint Source Survey. Radio data are presented for 899 MRKs
observed at ν=4.755GHz with the NRAO-Green Bank 300 foot (91m)
telescope, including nearly 88% of those objects in Markarian list
VI-XIV. In addition, 1.415GHz measurements of 258 MRKs, over 30% of
the MRKs accessible from NAIC-Arecibo, are reported. Radio continuum
observations of smaller numbers of MRKs were made at 10.63GHz and at
23.1GHz and are also presented.
