LOFAR Deep Fields: Probing a broader population of polarized radio galaxies in ELAIS-N1
N. Herrera Ruiz, S. P. O'Sullivan, V. Vacca +19
We present deep polarimetric observations of the European Large Area ISO Survey-North 1 (ELAIS-N1) field using the Low Frequency Array (LOFAR) at 114.9-177.4 MHz. The ELAIS-N1 fiel…
Reaching thermal noise at ultra-low radio frequencies: the Toothbrush radio relic downstream of the shock front
F. de Gasperin, G. Brunetti, M. Bruggen +14
Ultra-low frequency observations (<100 MHz) are particularly challenging because they are usually performed in a low signal-to-noise ratio regime due to the high sky temperature an…
The beautiful mess in Abell 2255
A. Botteon, G. Brunetti, R. J. van Weeren +18
We present LOFAR observations of one of the most spectacular objects in the radio sky: Abell 2255. This is a nearby () merging galaxy cluster hosting one of the first r…
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…
The LOFAR view of intergalactic magnetic fields with giant radio galaxies
C. Stuardi, S. P. O'Sullivan, A. Bonafede +8
Giant radio galaxies (GRGs) are physically large radio sources that extend well beyond their host galaxy environment. Their polarization properties are affected by the poorly const…
LOFAR 144-MHz follow-up observations of GW170817
J. W. Broderick, T. W. Shimwell, K. Gourdji +66
We present low-radio-frequency follow-up observations of AT 2017gfo, the electromagnetic counterpart of GW170817, which was the first binary neutron star merger to be detected by A…
