Description
he second data release of the LOFAR Two-Metre Sky Survey (LoTSS)
covers 27% of the northern sky, with a total area of ∼ 5,700 deg$^2$. We
have used a combination of automatic cross-matching, citizen science,
and expert visual inspection to find optical identifications for
around 3.5 million radio sources in the survey, generating by far the
largest catalogue of identified radio sources ever and providing some
important learning points for the SKA era. The unsurpassed statistics
of the dataset allow us to pioneer new approaches to removing star
formation contamination from AGN samples, generating of order 500,000
robustly selected AGN. These in turn allow new tests of radio AGN
unified models, and greatly improved estimates of the importance of
AGN feedback in the local universe. I'll discuss some preliminary
results from these projects.
