Visited the Swedish LOFAR station near Onsala. Happy to report that the first international LOFAR2.0 station is looking great!

Today is paper day again! Right now on arXiv: LOFAR-VLBI observations of Abell 2199, revealing a set of steep-spectrum synchrotron threads for the first time. Also, the radio lobes show an almost perfectly homogeneous CRe population. (arxiv.org/abs/2606.30714 w/ @andreabotteon.bsky.social)

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... ;)

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?
