We present the first wide area (19 deg2), deep (≈ 120–150 μJy beam−1), high resolution (5.6× 7.4 arcsec) LOFAR High Band Antenna image of the Bo ̈otes field made at 130-169 MHz. This image is at least an order of magnitude deeper and 3 − 5 times higher in angular resolution than previously achieved for this field at low frequencies. The...

We present a new analysis of the widely used relation between cavity power and radio luminosity in clusters of galaxies with evidence for strong AGN feedback. We studied the correlation at low radio frequencies using two new surveys – the first alternative data release of the TIFR GMRT Sky Survey (TGSS ADR1) at 148 MHz and LOFAR's firstall-sky...

The MIGHTEE large survey project will survey four of the most well-studied extragalactic deep fields, totalling 20 square degrees to $\mu$Jy sensitivity at Giga-Hertz frequencies, as well as an ultra-deep image of a single ~1 square degree MeerKAT pointing. The observations will provide radio continuum, spectral line and polarisation...
