A Giant Radio Halo in the Massive and Merging Cluster
We report on the detection of diffuse radio emission in the X-ray luminous and massive galaxy cluster A 1351 (z=0.322) using archival Very Large Array data at 1.4 GHz. Given its central location, morphology and Mpc-scale extent, we classify the diffuse source as a giant radio halo. X-ray and weak lensing studies show A 1351 to be a system undergoing a major merger. The halo is associated to the...
متن کاملDiscovery of a Giant Radio Halo in a New Planck Galaxy Cluster Plckg171.9-40.7
We report the discovery of a giant radio halo in a new, hot, X-ray luminous galaxy cluster recently found by Planck, PLCKG171.9-40.7. The radio halo was found using Giant Metrewave Radio Telescope observations at 235 MHz and 610 MHz, and in the 1.4 GHz data from a NRAO Very Large Array Sky Survey pointing that we have reanalyzed. The diffuse radio emission is coincident with the cluster X-ray e...
متن کاملInternal dynamics of the radio – halo cluster A 2219 : a multi – wavelength analysis
We present the results of the dynamical analysis of the rich, hot, and X–ray very luminous galaxy cluster A2219, containing a powerful diffuse radio–halo. Our analysis is based on new redshift data for 27 galaxies in the cluster region, measured from spectra obtained at the TNG, with the addition of other 105 galaxies recovered from reduction of CFHT archive data in a cluster region of ∼ 5 radi...
متن کاملInternal dynamics of the radio halo cluster A 2744
Aims. We present a detailed dynamical analysis of the rich galaxy cluster A2744, containing a powerful diffuse radio halo. Methods. Our analysis is based on redshift data for 102 galaxies, part of them recovered from unexplored spectra in the ESO archive. We combine galaxy velocity and position information to select the cluster members and determine global dynamical properties of the cluster. W...
متن کاملDetection of a radio halo in the Virgo cluster ⋆
New Effelsberg 1.4 GHz observations of the central 10◦ × 10◦ of the Virgo cluster are presented. NVSS data are used to subtract point sources from our map. During the data reduction process special care is taken (i) to disentangle emission from the North Polar Spur from emission from the Virgo cluster, (ii) to disentangle emission from the strong M87 sidelobes from emission from the Virgo clust...
