Deep Low-Frequency Radio Observations of the NOAO Bootes Field: I. Data Reduction and Catalog Construction
H. T. Intema, R. J. van Weeren, H. J. A. Rottgering +1
In this article we present deep, high-resolution radio interferometric observations at 153 MHz to complement the extensively studied NOAO Bootes field. We provide a description of…
Radio continuum observations of new radio halos and relics from the NVSS and WENSS surveys
R. J. van Weeren, M. Bruggen, H. J. A. Rottgering +3
Radio halos and relics are diffuse radio sources found in galaxy clusters showing significant substructure at X-ray wavelengths. These sources provide important information about n…
Discovery of the correspondence between intra-cluster radio emission and a high pressure region detected through the Sunyaev-Zel'dovich effect
C. Ferrari, H. T. Intema, E. Orrù +9
We analyzed new 237 MHz and 614 MHz GMRT data of the most X-ray luminous galaxy cluster, RX J1347-1145. Our radio results are compared with the MUSTANG 90 GHz Sunyaev-Zel'dovich ef…
The Curious Case of Abell 2256
Tracy E. Clarke, Torsten Enßlin, Alexis Finoguenov +5
Abell 2256 is a rich, nearby (z=0.0594) galaxy cluster that has significant evidence of merger activity. We present new radio and X-ray observations of this system. The low-frequen…
A double radio relic in the merging galaxy cluster ZwCl 0008.8+5215
R. J. van Weeren, M. Hoeft, H. J. A. Rottgering +3
Some merging galaxy clusters host diffuse elongated radio sources, also called radio relics. It is proposed that these radio relics trace shock waves in the intracluster medium cre…
Low-frequency radio observations of the galaxy cluster CIZA J2242.8+5301
R. J. van Weeren, H. T. Intema, H. J. A. Rottgering +2
Some disturbed galaxy clusters host diffuse elongated radio sources, also called radio relics. It is proposed that these relics trace shock waves in the intracluster medium (ICM).…
