Blazars in the LOFAR Two Metre Sky Survey First Data Release

The LOFAR Surveys Key Science Project have produced a survey of the northern hemisphere sky, called the LOFAR Two Metre Sky Survey. The First Data release is described in Shimwell et al. (2018). I used this survey to study the blazars which fall within the survey's footprint. My study is described in Mooney et al. (2018). The images of the blazars studied in the paper are shown here, where the colour scale is tightened to highlight some of the artefacts.
