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…
Red nuggets grow inside-out: evidence from gravitational lensing
Lindsay Oldham, Matt Auger, Chris Fassnacht +7
We present a new sample of strong gravitational lens systems where both the foreground lenses and background sources are early-type galaxies. Using imaging from HST/ACS and Keck/NI…
A large light-mass component of cosmic rays at 10^{17} - 10^{17.5} eV from radio observations
S. Buitink, A. Corstanje, H. Falcke +101
Cosmic rays are the highest energy particles found in nature. Measurements of the mass composition of cosmic rays between 10^{17} eV and 10^{18} eV are essential to understand whet…
A new VLA/e-MERLIN limit on central images in the gravitational lens system CLASS B1030+074
Jonathan Quinn, Neal Jackson, Amitpal Tagore +8
We present new VLA 22-GHz and e-MERLIN 5-GHz observations of CLASS B1030+074, a two-image strong gravitational lens system whose background source is a compact flat-spectrum radio…
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…
Radio follow-up of the gamma-ray flaring gravitational lens JVAS B0218+357
Cristiana Spingola, D. Dallacasa, M. Orienti +13
We present results on multifrequency Very Long Baseline Array (VLBA) monitoring observations of the double-image gravitationally lensed blazar JVAS B0218+357. Multi-epoch observati…
