The WEAVE-LOFAR Survey
D. J. B. Smith, P. N. Best, K. J. Duncan +27
In these proceedings we highlight the primary scientific goals and design of the WEAVE-LOFAR survey, which will use the new WEAVE spectrograph on the 4.2m William Herschel Telescop…
The LOFAR Two-metre Sky Survey - I. Survey Description and Preliminary Data Release
T. W. Shimwell, H. J. A. Röttgering, P. N. Best +69
The LOFAR Two-metre Sky Survey (LoTSS) is a deep 120-168 MHz imaging survey that will eventually cover the entire Northern sky. Each of the 3170 pointings will be observed for 8 hr…
The Lockman Hole project: LOFAR observations and spectral index properties of low-frequency radio sources
E. K. Mahony, R. Morganti, I. Prandoni +21
The Lockman Hole is a well-studied extragalactic field with extensive multi-band ancillary data covering a wide range in frequency, essential for characterising the physical and ev…
and observations of a newly-discovered early-stage cluster merger 1E2216.0-0401 and 1E2215.7-0404
H. Akamatsu, L. Gu, T. W. Shimwell +6
We present the results of and X-ray observations of the cluster pair 1E2216.0-0401 and 1E2215.7-0404. We discover an X-ray bridge between the clusters. $Suzak…
The Australian Square Kilometre Array Pathfinder: Performance of the Boolardy Engineering Test Array
D. McConnell, J. R. Allison, K. Bannister +71
We describe the performance of the Boolardy Engineering Test Array (BETA), the prototype for the Australian Square Kilometre Array Pathfinder telescope ASKAP. BETA is the first ape…
LOFAR/H-ATLAS: A deep low-frequency survey of the Herschel-ATLAS North Galactic Pole field
M. J. Hardcastle, G. Gürkan, R. J. van Weeren +25
We present LOFAR High-Band Array (HBA) observations of the Herschel-ATLAS North Galactic Pole survey area. The survey we have carried out, consisting of four pointings covering aro…
LOFAR VLBI Studies at 55 MHz of 4C 43.15, a z=2.4 Radio Galaxy
Leah K. Morabito, Adam T. Deller, Huub Röttgering +8
The correlation between radio spectral index and redshift has been exploited to discover high redshift radio galaxies, but its underlying cause is unclear. It is crucial to charact…
LOFAR 150-MHz observations of the Boötes field: Catalogue and Source Counts
W. L. Williams, R. J. van Weeren, H. J. A. Röttgering +32
We present the first wide area (19 deg), deep ( μJy beam), high resolution ( arcsec) LOFAR High Band Antenna image of the Boötes field ma…
A plethora of diffuse steep spectrum radio sources in Abell 2034 revealed by LOFAR
T. W. Shimwell, J. Luckin, M. Brüggen +28
With Low-Frequency Array (LOFAR) observations, we have discovered a diverse assembly of steep spectrum emission that is apparently associated with the intra cluster medium (ICM) of…
Wide-field broadband radio imaging with phased array feeds: a pilot multi-epoch continuum survey with ASKAP-BETA
I. Heywood, K. W. Bannister, J. Marvil +45
The Boolardy Engineering Test Array is a 6 x 12 m dish interferometer and the prototype of the Australian Square Kilometre Array Pathfinder (ASKAP), equipped with the first generat…
LOFAR, VLA, and Chandra observations of the Toothbrush galaxy cluster
R. J. van Weeren, G. Brunetti, M. Brüggen +39
We present deep LOFAR observations between 120-181 MHz of the "Toothbrush" (RX J0603.3+4214), a cluster that contains one of the brightest radio relic sources known. Our LOFAR obse…
LOFAR facet calibration
R. J. van Weeren, W. L. Williams, M. J. Hardcastle +39
LOFAR, the Low-Frequency Array, is a powerful new radio telescope operating between 10 and 240 MHz. LOFAR allows detailed sensitive high-resolution studies of the low-frequency rad…
