The LOFAR Two-metre Sky Survey: VII. Third Data Release

T. W. Shimwell, M. J. Hardcastle, C. Tasse +99

We present the third data release of the LOFAR Two-metre Sky Survey (LoTSS-DR3). The survey images cover 88% of the northern sky and were created from 12,950 hrs of data (18.6 PB)…

Spectral modelling of Cygnus A between 110 and 250 MHz. Impact on the LOFAR 21-cm signal power spectrum

E. Ceccotti, A. R. Offringa, L. V. E. Koopmans +15

Studying the redshifted 21-cm signal from the the neutral hydrogen during the Epoch of Reionization and Cosmic Dawn is fundamental for understanding the physics of the early univer…

Radio imaging of gravitationally lensed radio-quiet quasars

Neal Jackson, Shruti Badole, Thomas Dugdale +4

We present 6-GHz Very Large Array radio images of 70 gravitational lens systems at 300-mas resolution, in which the source is an optically-selected quasar, and nearly all of which…

On the source counts of VLBI-detected radio sources and the prospects of all-sky surveys with current and next generation instruments

S. Rezaei, J. P. McKean, A. T. Deller +1

We present an analysis of the detection fraction and the number counts of radio sources imaged with Very Long Baseline Interferometry (VLBI) at 1.4 GHz as part of the mJIVE-20 surv…

Mass Along the Line of Sight to the Gravitational Lens B1608+656: Galaxy Groups and Implications for H_0

C. D. Fassnacht, R. R. Gal, L. M. Lubin +3

We report the discovery of four groups of galaxies along the line of sight to the B1608+656 gravitational lens system. One group is at the redshift of the primary lensing galaxy (z…
