X-ray investigation of the remarkable galaxy group Nest200047

Anwesh Majumder, A. Simionescu, T. Plšek +11

Galaxy groups are more susceptible to feedback from the central active galactic nuclei (AGN) due to their lower gravitational binding energy compared to clusters. This makes them i…

LOFAR imaging of Cygnus A -- Direct detection of a turnover in the hotspot radio spectra

J. P. McKean, L. E. H. Godfrey, S. Vegetti +75

The low-frequency radio spectra of the hotspots within powerful radio galaxies can provide valuable information about the physical processes operating at the site of the jet termin…

The LOFAR Two-metre Sky Survey - II. First data release

T. W. Shimwell, C. Tasse, M. J. Hardcastle +104

The LOFAR Two-metre Sky Survey (LoTSS) is an ongoing sensitive, high-resolution 120-168MHz survey of the entire northern sky for which observations are now 20% complete. We present…

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…

AGN duty cycle estimates for the ultra-steep spectrum radio relic VLSS J1431.8+1331

A. Shulevski, R. Morganti, P. D. Barthel +19

Steep spectrum radio sources associated with active galactic nuclei (AGN) may contain remnants of past AGN activity episodes. Novel instruments like the LOw Frequency ARray (LOFAR)…
