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…
The Cosmic Dawn and Epoch of Reionization with the Square Kilometre Array
L. V. E. Koopmans, J. Pritchard, G. Mellema +42
Concerted effort is currently ongoing to open up the Epoch of Reionization (EoR) (15-6) for studies with IR and radio telescopes. Whereas IR detections have been made of sou…
A relation between circumnuclear HI, dust, and optical cores in low-power radio galaxies
Ilse M. van Bemmel, Raffaella Morganti, Tom Oosterloo +1
From new observations and literature data we investigate the presence of HI, dust, and optical cores in the central kiloparsec of low-power radio galaxies. The goal of this pilot s…
First LOFAR results on galaxy clusters
C. Ferrari, I. van Bemmel, A. Bonafede +21
Deep radio observations of galaxy clusters have revealed the existence of diffuse radio sources related to the presence of relativistic electrons and weak magnetic fields in the in…
First LOFAR observations at very low frequencies of cluster-scale non-thermal emission: the case of Abell 2256
R. J. van Weeren, H. J. A. Rottgering, D. A. Rafferty +79
Abell 2256 is one of the best known examples of a galaxy cluster hosting large-scale diffuse radio emission that is unrelated to individual galaxies. It contains both a giant radio…
LOFAR and APERTIF surveys of the radio sky: probing shocks and magnetic fields in galaxy clusters
Huub Rottgering, Jose Afonso, Peter Barthel +32
At very low frequencies, the new pan-European radio telescope LOFAR is opening the last unexplored window of the electromagnetic spectrum for astrophysical studies. The revolutiona…
LOFAR: Recent imaging results & future prospects
George Heald, Michael R. Bell, Andreas Horneffer +27
The Low Frequency Array (LOFAR) is under construction in the Netherlands and in several surrounding European countries. In this contribution, we describe the layout and design of t…
LOFAR: Early imaging results from commissioning for Cygnus A
John McKean, Louise Ker, Reinout J. van Weeren +19
The Low Frequency Array (LOFAR) will operate between 10 and 250 MHz, and will observe the low frequency Universe to an unprecedented sensitivity and angular resolution. The constru…
