Decameter radio observations have always been very difficult due to the ionosphere. @ChristianGroe18 et al. present a strategy to correct for the ionosphere, which allows them to make sharp decameter radio images from the surface of the Earth. nature.com/articles/s41550-0…

Big announcement on the HPF blog: our HPF exoplanet survey has discovered a Neptune-mass exoplanet on a close-in orbit around a very low-mass star. This planet challenges our understanding of planet formation around low-mass stars: sites.psu.edu/hzpf/2023/11/3…

We're already starting to see possible Dutch coalitions put forward in the wake of yesterday's election.
So here's a run-through of the permutations.

Hiding in plain sight: a cosmic balled of black holes. This image shows my composite of the @LOFAR 144 MHz view of the Perseus cluster overlaid on the amazing image released by @ESA_Euclid last week.

#TBT to Karl Jansky’s accidental discovery of radio emission from the heart of our galaxy, which was widely publicized this week in 1933. This kicked off the field of radio astronomy, and we now know our galactic center houses a supermassive black hole. #BlackHoleWeek
ALT Karl Guthe Jansky joined the staff of the Bell Telephone Laboratories in Holmdel, New Jersey, in 1928. While hunting for radio static for Bell Labs, Jansky made the surprise discovery of radio waves coming from the center of our Milky Way galaxy. In this photo, he is standing under a rough map of the night sky and pointing to the constellation Cassiopeia. The wavy lines track the radio emissions he discovered on the chart paper, which also line up with the disk of our galaxy, the Milky Way.

Prof. Jason Hessels has been granted €3.5 million by the European Research Council to probe the origins of Fast Radio Bursts! 💥📡 It will be used to upgrade the instrumentation of the European VLBI Network and LOFAR telescopes, and fund a research team. api.uva.nl/content/news/2023…

ASPIRE’s deadline is approaching! 🔭
Don't forget to submit your applications by March 1st.
ASPIRE is a 6-week in-person summer research program aimed at MSc students. It is a great opportunity to perform research at Anton Pannekoek Institute for Astronomy.

4 years later the results are here. This is just stunning. JWST is an engineering miracle.
Peredur Williams shows the planned JWST observations of the dust producing Wolf-Rayet 140. Want to see if there are any molecules and get the extended thermal observation #EWASS2018

How to find exoplanets with rings? How to detect life around a radio star? 💫 @mattkenworthy and @AstroJoeC will try to answer these questions at #AoTLeiden today 20:00 ✨
Mark your calendars for the next #AoTLeiden event 📅26 September 20:00 ⏰ with @mattkenworthy and @AstroJoeC from Leiden Observatory 🔭✨🍻

Want to calibrated cm-VLBI data w/ CASA - check out the pipeline I made here - github.com/jradcliffe5/VLBI_…
p.s., it actually has documentation now.

New Physics 🧵! Ludwig Boltzmann was not just a father of Statistical Physics but also a master of Thermodynamics. That’s how he got his name on the Stefan-Boltzmann law. If you allow me, I would love to walk you through a magic moment in physics history. /1

Very happy to contribute a chapter on Monte Carlo and MCMC to this popular book on algorithms edited by @thekibosch from @PrincetonUPress - "You Are Not Expected to Understand This": How 26 Lines of Code Changed the World".
Coming out November 15!
