The LOFAR sub-arcsecond view of the high-redshift radio relic in PSZ2G091.83+26.11
G. Di Gennaro, R. Timmerman, M. Hoeft +14
Enhanced inverse Compton (IC) losses at high redshift steepen diffuse radio spectra in galaxy clusters, making low-frequency (~100 MHz) observations favorable. However, low-frequen…
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)…
Scalable and robust wide-field facet calibration with LOFAR's longest baselines
J. M. G. H. J. de Jong, L. Veefkind, R. J. van Weeren +8
Recent work has successfully achieved sub-arcsecond wide-field imaging with high-band observations from the Low Frequency Array (LOFAR). However, the scalability of this work remai…
Unlocking ultra-deep wide-field imaging with sidereal visibility averaging
J. M. G. H. J. de Jong, R. J. van Weeren, T. J. Dijkema +3
Producing ultra-deep high-angular-resolution images with current and next-generation radio interferometers introduces significant computational challenges. In particular, the imagi…
A hidden Active Galactic Nuclei population: the first radio luminosity functions constructed by physical process
Leah K. Morabito, R. Kondapally, P. N. Best +10
Both star formation (SF) and Active Galactic Nuclei (AGN) play an important role in galaxy evolution. Statistically quantifying their relative importance can be done using radio lu…
