Astro-COLIBRI recap of 2025! 😁 🔭🧪⚛️ youtube.com/shorts/bqo4r...

A nicely timed meeting of the Astroparticle Physics European Consortium (APPEC) General Assembly in Stockholm during the Nobel Prizel week. Enjoyed the art installations and listened to the Nobel lecturs on Physics (incl. Michel Devoret who is well known at my institute at CEA Paris-Saclay). 🔭🧪⚛️

We've just released a massive update to Astro-COLIBRI! 🔭☄️🧪⚛️ Version 2.25.0 features a completely redesigned mobile experience (yes, you can finally swipe between screens!) and adds powerful new data sources like the RAPAS network and LAST Observatory. More details in our forum: tinyurl.com/ACv2-25

Wonderful news for science! 🔭🧪⚛️☄️

Go THESEUS! 😜 🔭🧪☄️

Today, the international LIGO-Virgo-KAGRA Collaboration celebrates the successful completion of its 4th observing run (O4), marking another major step forward in the exploration of the gravitational wave universe. The run relied on coordinated observations and analyses by teams across the world. 🧪🔭

"Prohibited activities would include joint research, co-authorship & advising a foreign graduate student or postdoc. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding." Dictators despise science.

After a bruising 42-day shutdown, the government has finally reopened. We took a look at what's next for federal science—how quickly things will get back up to speed and whether there will be long-term consequences. With Jeff Tollefson and @alexwitze.bsky.social:

Explor'Espace 2025 is on! Astro-COLIBRI is teaming up with the CTAO group at CEA Paris-Saclay to showcase high-energy and transient astrophysics to a wide (and very numerous) audience. A whole weekend full of interesting exchanges ahead... 🔭🧪⚛️ explorespace.afastronomie.fr

Surprising news from the GW observatories LIGO, Virgo, and KAGRA just published via an update of their observing plans: they'll still shut-down on November 18, 2025 as announced earlier but now plan for an additional 6 month of science run next year. ☄️🔭🧪⚛️ observing.docs.ligo.org/plan/

The #arXiv computer science category is trying to cut down on AI slop spamming the system. They no longer accept un-published (journal or conference) review papers... Other categories may follow (depending on decisions by the moderators). ⚛️🧪☄️ blog.arxiv.org/2025/10/31/a...

If you are in Paris/France over the coming weekend (November 7-9) you should plan for a visit at the Explor'Espace space and science event. The Astro-COLIBRI team will be there to discuss time domain and multi-messenger astrophysics. 🔭🧪⚛️ explorespace.afastronomie.fr
