Physical insights from the spectrum of the radio halo in MACS J0717.5+3745
K. Rajpurohit, G. Brunetti, A. Bonafede +18
We present new LOFAR observations of the massive merging galaxy cluster MACS J0717.5+3745. The cluster hosts the most powerful radio halo known to date. These new observations, in…
Understanding the radio relic emission in the galaxy cluster MACS J0717.5+3745: spectral analysis
K. Rajpurohit, D. Wittor, R. J. van Weeren +21
Radio relics are diffuse, extended synchrotron sources that originate from shock fronts generated during cluster mergers. The massive merging galaxy cluster MACS J0717.5+3745 hosts…
A perfect power-law spectrum even at highest frequencies: The Toothbrush relic
K. Rajpurohit, F. Vazza, M. Hoeft +12
Radio relics trace shock fronts generated in the intracluster medium (ICM) during cluster mergers. The particle acceleration mechanism at the shock fronts is not yet completely und…
Discovery of a Radio Relic in the Massive Merging Cluster SPT-CL 2023-5535 from the ASKAP-EMU PILOT SURVEY
Kim HyeongHan, M. James Jee, Lawrence Rudnick +11
The ASKAP-EMU survey is a deep wide-field radio continuum survey designed to cover the entire southern sky and a significant fraction of the northern sky up to . Here,…
Magnetism Science with the Square Kilometre Array
George Heald, Sui Ann Mao, Valentina Vacca +41
The Square Kilometre Array (SKA) will answer fundamental questions about the origin, evolution, properties, and influence of magnetic fields throughout the Universe. Magnetic field…
The GLEAM 4-Jy (G4Jy) Sample: I. Definition and the catalogue
Sarah V. White, Thomas M. O. Franzen, Chris J. Riseley +21
The Murchison Widefield Array (MWA) has observed the entire southern sky (Declination, 30 deg) at low radio-frequencies, over the range 72-231 MHz. These observations constitu…
The GLEAM 4-Jy (G4Jy) Sample: II. Host-galaxy identification for individual sources
Sarah V. White, Thomas M. O. Franzen, Chris J. Riseley +20
The entire southern sky (Declination, 30 deg) has been observed using the Murchison Widefield Array (MWA), which provides radio imaging of 2-arcmin resolution at low fre…
The POlarised GLEAM Survey (POGS) II: Results from an All-Sky Rotation Measure Synthesis Survey at Long Wavelengths
C. J. Riseley, T. J. Galvin, C. Sobey +11
The low-frequency linearly-polarised radio source population is largely unexplored. However, a renaissance in low-frequency polarimetry has been enabled by pathfinder and precursor…
Low-frequency observations of the Giant Radio Galaxy NGC 6251
T. M. Cantwell, J. D. Bray, J. H. Croston +22
We present LOFAR observations at 150 MHz of the borderline FRI/FRII giant radio galaxy NGC 6251. This paper presents the most sensitive and highest-resolution images of NGC 6251 at…
SuperCLASS -- III. Weak lensing from radio and optical observations in Data Release 1
Ian Harrison, Michael L. Brown, Ben Tunbridge +17
We describe the first results on weak gravitational lensing from the SuperCLASS survey: the first survey specifically designed to measure the weak lensing effect in radio-wavelengt…
SuperCLASS -- II: Photometric Redshifts and Characteristics of Spatially-Resolved Jy Radio Sources
Sinclaire M. Manning, Caitlin M. Casey, Chao-Ling Hung +12
We present optical and near-infrared imaging covering a 1.53 deg region in the Super-Cluster Assisted Shear Survey (SuperCLASS) field, which aims to make the first robust…
SuperCLASS -- I. The Super CLuster Assisted Shear Survey: Project overview and Data Release 1
Richard A. Battye, Michael L. Brown, Caitlin M. Casey +24
The SuperCLuster Assisted Shear Survey (SuperCLASS) is a legacy programme using the e-MERLIN interferometric array. The aim is to observe the sky at L-band (1.4 GHz) to a r.m.s. of…
