On arXiv: the deepest observation ever carried out by @LOFAR, by Shimwell+
We used 505 h of data at 150 MHz on the ELAIS-N1 field and produced a 6" image (rms 10.7 muJy/b) and a catalog of +150k sources (see lofar-surveys.org/deepfields…). Stay tuned for more...

🎆@ctao_universe is now officially an ERIC! Welcome to the ERIC family! With three astronomy #ERICs—CTAO, @LOFAR, and JIVE, we expand our ability to observe the Universe from both ends of the electromagnetic spectrum. nitter.siddz.com/ctao_universe/status/1… @EU_Commission @ERIC_forum
Big news! The CTAO is now officially an ERIC! 🚀
The @EU_commission has established the CTAO as a European Research Infrastructure Consortium, fast-tracking construction and bringing early science closer. 🌌✨

🌌 #SpaceX's 2nd gen Starlink satellites are leaking up to 32 times more unintended radio waves than the 1st gen, potentially blinding telescopes like LOFAR and jeopardizing our understanding of the Universe!

I am incredibly lucky and privileged to announce that I have been awarded an @ERC_Research starting grant! I will be using it to discover the space weather of other worlds using telescopes such as @LOFAR and @SKAO at @ASTRON #ERCStG

Opening ceremony for @LOFAR becoming a European Research Infrastructure consortium! Sadly we have a classic summer Dutch day, with the weather not being considerate to the milestone.

Using a new calibration technique, LOFAR can produce even sharper radio galaxy images than before.
Radio astronomers bypass disturbing Earth's atmosphere with new calibration technique.

ALT Old versus new. Two black panels with orange spots. The left panel shows an image of a piece of sky observed with the hitherto best calibration technique. Right shows the same piece of sky with the new technique. In the right panel is more detail visible. And what were once large, blurry patches now appear as single points. (c) LOFAR/Groeneveld et al.
