Happy to have been a coauthor on this paper led by Maria Arias and @rtimmerman.bsky.social looking at the crab nebula with the full International #LOFAR Telescope that was put on arxiv yesterday! Lots of nice sub-arcsecond detail is revealed. Go check out the paper on arxiv arxiv.org/abs/2506.19460

Another exciting paper that I am thrilled to have contributed to landed on arxiv earlier this week: a review of the last decade of high resolution imaging with LOFAR! Head over there now to see how far we have come in just a decade and what exciting prospects lie ahead. arxiv.org/abs/2502.06946
A decade of sub-arcsecond imaging with the International LOFAR Telescope
The International LOFAR Telescope (ILT) is a pan-European radio interferometer with baselines up to 2,000 km. This provides sub-arcsecond resolution at frequencies of <200 MHz. Since starting science ...
