The non-thermal superbubble in IC 10: the generation of cosmic ray electrons caught in the act
Volker Heesen, Elias Brinks, Martin G. H. Krause +6
Superbubbles are crucial for stellar feedback, with supposedly high (of the order of 10 per cent) thermalization rates. We combined multiband radio continuum observations from the…
LOFAR low-band antenna observations of the 3C295 and Bootes fields: source counts and ultra-steep spectrum sources
R. J. van Weeren, W. L. Williams, C. Tasse +98
We present LOFAR Low Band observations of the Bootes and 3C295 fields. Our images made at 34, 46, and 62 MHz reach noise levels of 12, 8, and 5 mJy beam, making them the dee…
Spectral age modelling of the `Sausage' cluster radio relic
Andra Stroe, Jeremy J. Harwood, Martin J. Hardcastle +1
CIZA J2242.8+5301 is a post-core passage, binary merging cluster that hosts a large, thin, arc-like radio relic, nicknamed the `Sausage', tracing a relatively strong shock front. W…
The spectral structure and energetics of powerful radio sources
J. J. Harwood, M. J. Hardcastle, J. H. Croston +3
Determining the energy spectrum of an electron population can give key insights into the underlying physics of a radio source; however, the lack of high resolution, broad-bandwidth…
Spectral and morphological signatures of cluster merger shocks: CIZA J2242.8+5301
Andra Stroe, Reinout J. van Weeren, David Sobral +7
The CIZA J2242.8+5301 cluster hosts an extraordinary, narrow, Mpc-wide, diffuse patch of radio emission tracing travelling shock waves, called a relic. We perform a multi-wavelengt…
The highest-frequency detection of a radio relic: 16-GHz AMI observations of the `Sausage' cluster
Andra Stroe, Clare Rumsey, Jeremy J. Harwood +6
We observed the cluster CIZA J2242.8+5301 with the Arcminute Microkelvin Imager at GHz and present the first high radio-frequency detection of diffuse, non-thermal cluster emi…
