Serendipitous decametre detection of ultra steep spectrum radio emission in Abell 655
C. Groeneveld, R. J. van Weeren, A. Botteon +5
Some galaxy clusters contain non-thermal synchrotron emitting plasma permeating the intracluster medium (ICM). The spectral properties of this radio emission are not well character…
Probing cluster magnetism with embedded and background radio sources in Planck clusters
Erik Osinga, Reinout J. van Weeren, Lawrence Rudnick +6
Magnetic fields remain an enigmatic part of the content of galaxy clusters. Faraday rotation and depolarisation of extragalactic radio sources are useful probes, but the limited av…
Probing the Magnetised Gas Distribution in Galaxy Groups and the Cosmic Web with POSSUM Faraday Rotation Measures
Craig S. Anderson, N. M. McClure-Griffiths, L. Rudnick +21
We present initial results from the Polarisation Sky Survey of the Universe's Magnetism (POSSUM), analysing 22,817 Faraday Rotation Measures (RMs) with median uncertainties of 1.2…
Probing particle acceleration in Abell 2256: from to 16 MHz to gamma rays
E. Osinga, R. J. van Weeren, G. Brunetti +9
Merging galaxy clusters often host spectacular diffuse radio synchrotron sources. These sources can be explained by a non-thermal pool of relativistic electrons accelerated by shoc…
Characterization of the decametre sky at subarcminute resolution
C. Groeneveld, R. J. van Weeren, E. Osinga +11
The largely unexplored decameter radio band (10-30 MHz) provides a unique window for studying a range of astronomical topics, such as auroral emission from exoplanets, inefficient…
