LOFAR: opening a new window on low frequency radio astronomy
R. Morganti, G. Heald, J. Hessels +8
This contribution reports on the status of LOFAR (the LOw Frequency ARray) in its ongoing commissioning phase. The purpose is to illustrate the progress that is being made, often o…
How many radio relics await discovery?
S. E. Nuza, M. Hoeft, R. J. van Weeren +2
Upcoming radio telescopes will allow to study the radio sky at low frequencies with unprecedent sensitivity and resolution. New surveys are expected to discover a large number of n…
Why are central radio relics so rare?
F. Vazza, M. Brueggen, R. van Weeren +3
In this paper we address the question why cluster radio relics that are connected to shock acceleration, so-called radio gischt, have preferentially been found in the outskirts of…
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…
Using double radio relics to constrain galaxy cluster mergers: A model of double radio relics in CIZA J2242.8+5301
R. J. van Weeren, M. Bruggen, H. J. A. Rottgering +1
Galaxy clusters grow by mergers with other clusters and galaxy groups. These mergers create shock waves within the intracluster medium (ICM) that can accelerate particles to extrem…
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…
