The LOFAR Two-Metre Sky Survey : VI. Optical identifications for the second data release
(2023-10-01)
The second data release of the LOFAR Two-Metre Sky Survey (LoTSS) covers 27% of the northern sky, with a total area of ∼5700 deg1. The high angular resolution of LOFAR with Dutch baselines (6 arcsec) allows us to carry out ...
SKA Science Data Challenge 2: analysis and results
(2023-08-31)
The Square Kilometre Array Observatory (SKAO) will explore the radio sky to new depths in order to conduct transformational science. SKAO data products made available to astronomers will be correspondingly large and complex, ...
The LOFAR Two-metre Sky Survey: the radio view of the cosmic star formation history
(2023-05-26)
We present a detailed study of the cosmic star formation history over $90$ per cent of cosmic time ($0\lesssim z\lesssim4$), using deep, radio continuum observations that probe star formation activity independent of dust. ...
