Visited the optical astronomers last week. I asked them how they get any visibilities with their separate dishes, and they simply assured me that the visibility was great. I'm still confused... ;)

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

High-resolution LOFAR images used to be a rare commodity. Now we're starting to just hand them out for free! Here, enjoy this random radio galaxy :)
Be sure to keep an eye on the LoTSS-HR project!

How about this for a first Bluesky post? Me sitting on top of my favorite radio telescope: LOFAR! With a blue sky in the background; very fitting right?
