LoTSS-DR3, by Shimwell+ (w/ many) We have released the largest collection of data from a radio survey: 13M+ sources detected over 19k deg^2 (88% of the Northern sky). This took ~13k h of @LOFAR observations, ~18 PT of data, and 10+ years of work. Data are public from today arxiv.org/abs/2602.15949

What better to push into production at the end of a work day

When the code you overhauled massively runs and actually works

Daily driving @zen-browser.app for a bit has been a nice switch of browser. Built-in side-by-side tab view at the whim of a quick keyboard shortcut is not something I thought I missed.

The baboon luminosity function #NAM2025

LOFAR needs stickers you say? Well say no more

All set for the opening plenary of #NAM2025

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

quickref.me quite a nice cheat sheet collection for a variety of stuff.

Yep, ionosphere

In case you were wondering what uv coverage the Egyptian pyramids (well, those listed on Wikipedia at least) would achieve if they did decameter observations. @rtimmerman.bsky.social

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 ...

@rtimmerman.bsky.social digging into the topic of mysterious filaments in AGNs #SALFX

Kicking off #SALFX this morning learning about low frequency EoR studies and ram pressure stripping seen by LOFAR.

The Shanghai metro is quite amazing. Probably the most efficient public transport network I have experienced so far.

5 AM train to London this morning then flying off to Shanghai for the annual dose of low frequency science at #SALF 😱
