Abstract:
We aim to carry out a radio study of the SoUthern Cluster sCale
Extended Source Survey (SUCCESS) sample consisting of twenty massive
(M500>5x1014M☉), nearby (redshift <0.3) and southern
(-50°<δ←30°) galaxy clusters detected by the Planck
satellite and the South Pole Telescope. Here we report targeted GMRT
observations (325/610MHz) for the sub-sample of nine clusters. We also
use the first data release of MeerKAT Galaxy Cluster Legacy Survey
(1283MHz) for six of these nine clusters. The properties of the
mini-halo in RXC J0528.9-3927, a candidate mini-halo in A3322, the
radio halo and candidate double relics in A3399, and the radio halo in
RXC J0232.2-4420 are presented. We also report detection of candidate
radio relics at distances 1 and 1.9Mpc from the center of
RXC J0232.2-4420. The southeast relic of A3399 is consistent with the
radio power - mass scaling relation for radio relics, while the
candidate relics around RXC J0232.2-4420 are outliers. This indicates
an origin of the candidate relics near RXC J0232.2-4420 to be
independent of this cluster and a cluster merger-shock origin for the
relic in A3399. In this sub-sample of clusters 1/9 hosts a radio halo
and double relics, 1/9 hosts a radio halo and 2/9 host mini-halos. The
dynamical states based on X-ray morphology show that A3399 is a
disturbed cluster; however, the radio halo cluster RXC J0232.2-4420 is
relaxed, and the mini-halo clusters have intermediate morphologies,
adding to the cases of the less commonly found associations.
Description:
In each Tables, the discrete radio sources using PyBDSF in the cluster
field for the MeerKAT 1283MHz images are listed. The flux densities
only for the discrete sources situated in the region of the diffuse
emission within 3σrms contours are reported.
