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)

Published in #MNRAS: "Wiggling through the ICM: multiresolution radio imaging of a tailed radio galaxy in MACS J1354.6+7715", Gani et al. These are Figs. 1 & 6: please visit academic.oup.com/mnras/articl... to read the paper. @royalastrosoc.bsky.social @academic.oup.com

Radio observations A1775 and A1795, by vanWeeren+ (w/ @cjriseley.bsky.social, @rtimmerman.bsky.social, myself+) MeerKAT @SKA_Africa recovers the known diffuse emission in both systems. Interestingly, the large-scale halo in A1795 is compatible with a hardonic origin... arxiv.org/abs/2601.16288

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... ;)

#ASTRONOMY ‪10 billion light years away, in a cluster of galaxies, a vast cloud of high-energy particles is revealed, thanks to @umontreal.ca's Julie Hlavacek-Larrondo and @rtimmerman.bsky.social‬. #LOFAR nouvelles.umontreal.ca/en/article/2...

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?
