Faceting for direction-dependent spectral deconvolution
C. Tasse, B. Hugo, M. Mirmont +7
The new generation of radio interferometers is characterized by high sensitivity, wide fields of view and large fractional bandwidth. To synthesize the deepest images enabled by th…
Studying the late evolution of a radio-loud AGN in a galaxy group with LOFAR
Federica Savini, Annalisa Bonafede, Marcus Brüggen +17
Feedback by radio-loud active galactic nuclei (AGN) in galaxy groups is not fully understood. Open questions include the duty cycle of the AGN, the spatial extent of the radio lobe…
LOFAR reveals the giant: a low-frequency radio continuum study of the outflow in the nearby FR I radio galaxy 3C 31
V. Heesen, J. H. Croston, R. Morganti +21
We present a deep, low-frequency radio continuum study of the nearby Fanaroff--Riley class I (FR I) radio galaxy 3C 31 using a combination of LOw Frequency ARray (LOFAR; 30--85 and…
Gentle re-energisation of electrons in merging galaxy clusters
F. de Gasperin, H. T. Intema, T. W. Shimwell +6
Galaxy clusters are the most massive constituents of the large-scale structure of the Universe. While the hot thermal gas that pervades galaxy clusters is relatively well understoo…
LOFAR discovery of an ultra-steep radio halo and giant head-tail radio galaxy in Abell 1132
A. Wilber, M. Brüggen, A. Bonafede +16
LOFAR observations at 144 MHz have revealed large-scale radio sources in the unrelaxed galaxy cluster Abell 1132. The cluster hosts diffuse radio emission on scales of 650 kp…
AMI-CL J0300+2613: a Galactic anomalous-microwave-emission ring masquerading as a galaxy cluster
Yvette C. Perrott, Therese M. Cantwell, Steve H. Carey +17
The Arcminute Microkelvin Imager (AMI) carried out a blind survey for galaxy clusters via their Sunyaev-Zel'dovich effect decrements between 2008 and 2011. The first detection, kno…
Search and modelling of remnant radio galaxies in the LOFAR Lockman Hole field
M. Brienza, L. Godfrey, R. Morganti +8
The phase of radio galaxy evolution after the jets have switched off, often referred to as the remnant phase, is poorly understood and very few sources in this phase are known. In…
Deep LOFAR observations of the merging galaxy cluster CIZA J2242.8+5301
D. N. Hoang, T. W. Shimwell, A. Stroe +20
Previous studies have shown that CIZA J2242.8+5301 (the 'Sausage' cluster, ) is a massive merging galaxy cluster that hosts a radio halo and multiple relics. In this paper…
Investigating the Unification of LOFAR-detected powerful AGN in the Boötes Field
Leah K. Morabito, W. L. Williams, Kenneth J. Duncan +17
Low radio frequency surveys are important for testing unified models of radio-loud quasars and radio galaxies. Intrinsically similar sources that are randomly oriented on the sky w…
The two-component giant radio halo in the galaxy cluster Abell 2142
T. Venturi, M. Rossetti, G. Brunetti +9
We report on a spectral study at radio frequencies of the giant radio halo in A2142 (z=0.0909), which we performed to explore its nature and origin. A2142 is not a major merger and…
