A Westerbork survey of rich clusters of galaxies. VIII. Observations of the cluster Abell 1367 at 610 and 1415 MHz.
Abstract
Summary. The cluster of galaxies A 1367 has been observed with the Westerbork Synthesis Radio Telescope at the frequencies of 610 and 1415 MHz. Twelve galaxies have been detected (3 E + SO ; 9S+ Irr) allowing the determination of the Radio Luminosity Function of this cluster. No difference is found between the present RLF in the E + SO group and the general RLF of cluster and field galaxies. In the S + Irr group the fraction of galaxies radio emitting with P610 >= 1 ()21 .3 W Hz -1 in this cluster is lower than in the Coma cluster and comparable to that of the spirals in the field. As it was found in Coma, this fraction does not depend on the optical luminosity of the galaxies, while a correlation of this type was found in the sample of field spirals. The present data confirm that the power of the radio source associated with a spiral or Irregular galaxy in cluster correlates with the presence of emission lines in its spectrum. Key words,: clusters of galaxies - Radio Luminosity Function
