PLCK G004.5-19.5 images at 150, 325 and 610MHz
Listed in IVOA Registry (Virtual Observatory)
We present radio observations of the galaxy cluster PLCK G004.5-19.5 (z=0.52) using the Giant Metrewave Radio Telescope at 150MHz, 325MHz, and 610MHz.
Description
We find an unusual arrangement of diffuse radio emission in the center and periphery of the cluster, as well as several radio galaxies with head-tail emission. A patch of peripheral emission resembles a radio relic, and central emission resembles a radio halo.
Reanalysis of archival XMM-Newton X-ray data shows that PLCK G004.5-19.5 is disturbed, which has a known correlation with the existence of radio relics and halos. Given that the number of known radio halos and radio relics at z>0.5 is very limited, PLCK G004.5-19.5 is an important addition to understanding merger-related particle acceleration at higher redshifts.
