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

Here we go... the 4th Astro-COLIBRI Multi-Messenger Astrophysics workshop has begun... 🔭🧪⚛️☄️ indico.ijclab.in2p3.fr/event/11610/... The recordings will be published on our YouTube channel after the event. Subscribe there to stay up-to-date: www.youtube.com/@astro-colibri

We are pleased to announce that the Astrophysics Centre for Multimessenger Studies in Europe (ACME) EU-funded project has officially launched its online platform for virtual access to multi-messenger expertise. 🔭🧪⚛️☄️ support.acme-astro.eu Details in the thread below and on: www.acme-astro.eu

🚀💥 Astro-COLIBRI v2.24.0 is now live! This release is all about supernovae! We've added new filters, new notification streams, and a new figure. Plus, API enhancements, updated catalogs, an improved search for events, and many more. 🔭☄️🧪⚛️ Details in our forum post: tinyurl.com/2p2mncdu

The Neil Gehrels Swift Observatory is crucial for time domain astrophysics. Unfortunately its orbit is decaying and it will burn up in the atmosphere next year. But maybe there is a last minute hope... Fingers crossed! 🔭☄️🧪⚛️ www.katalystspace.com/post/nasa-te...

Radio detection of air-showers independent of a particle detector providing the trigger is a big step towards future observatories of cosmic rays and eventually ultra-high energy neutrinos! 🔭🧪

My new piece is live! While the atrocities of RFK Jr. are many (and well beyond what can be summarized in a single blog post), we at @standupforscience.bsky.social have selected the nine most atrocious. Read below 👇 www.standupforscience.net/blog/9-worst... #ImpeachRFKNow

A wonderfull paper for the summer vacation reading list.

Big day for the matriarchy! 🥳 Huge congrats to the awesome Prof. Doughtery, lead on the Jupiter-bound ESA JUICE mission & STFC Exec Chair. If anyone's confused on the astro royal hierarchy: Michele and I are the astro equivalents of 🇬🇧Westminster and 🏴󠁧󠁢󠁳󠁣󠁴󠁿Holyrood 🤗 ℹ️: www.bbc.co.uk/news/article... 👩‍🔬🔭🧪

How do we search for TeV gamma rays from FRBs? Our new H.E.S.S. paper sums up over a decade of efforts: from first follow-ups to real-time triggers and global MWL campaigns. No detections yet, but the search goes on! 🔭☄️ doi.org/10.1088/1475...

Indeed, very promising news for European research funding. 🔭☄️

No words...

A great excursion during ICRC2025 to one of the birthplaces of cosmic ray research: the Jungfraujoch research station where Auger, Leprince-Ringuet, Ehrenfest, et al. discovered extensive air showers. The research station remains active today, right in the middle of a crowded tourist destination. 🔭

We are excited to announce the discovery of #GW231123, a gravitational-wave signal from the merger of two high-mass black holes to form one about 190–265 times the mass of our Sun ligo.org/ligo-virgo-k... #O4IsHere 🔭🧪☄️

🔊 Two really massive black holes, COLLIDING💥! LIGO has seen ~300 of these collisions since 2015, but this one is HUGE creating a black hole 256x the mass of the Sun. It's likely the merging black holes were themselves the by-product of previous mergers 🤓🔭🧪 ℹ️: www.theguardian.com/science/2025...

Finally a gllmpse of hope... 🔭🧪⚛️☄️ www.nature.com/articles/d41...

From Skylar Grayson @skylargrayson.bsky.social : This post summarizes the proposed major cuts to NASA and the NSF and the impacts they would have, and provides resources to help fight back against this wasteful and unnecessary attack on science. 🔭✨☄️ astrobites.org/2025/06/02/b...

🔥@philplait.bsky.social's excellent newsletter: "This isn’t a budget cut. It’s an execution. I don’t say this lightly. This proposed budget will ring the death knell for NASA as we know it." What can non-US based astros do to help support the fight? 🔭🧪 badastronomy.beehiiv.com/p/trump-thre...

Here's NASA astrophysics, if I read the president's proposed budget correctly. 🔭

There's a lot to unpack in the president's FY26 requested #NASA budget, but the near zeroing of the physics of the cosmos program (from $196M to $1.5M) is especially bleak. If passed, the future of high-energy astrophysics is not in the US. 🔭

"Why should my tax dollars go to fund your astrophysics research?" A thread. 🔭🧪 Brushing aside how absurdly little of the federal budget goes to science (according to the Planetary Society NASA accounts for only 0.3% of federal spending), the benefits of funding astronomy fall into two camps. (1/n)

How bad will it be? Catastrophic. Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come. But, this is the WH's *proposed* budget. Speak up now before it is too late. (inflation adjusted $-s below)

The details of the proposed budget cuts to NSF are just horrific. 🔭🧪⚛️☄️ Example: "the astronomical community will be stunned that the agency intends to wind down one of the sites for the celebrated Laser Interferometer Gravitational-Wave Observatory (LIGO)." WTF? www.science.org/content/arti...

Speechless... 🔭🧪⚛️☄️ We knew from the earlier versions that this will be bad, but reading the actual numbers and details is still stunning. www.science.org/content/arti...

Are you based in the U.S. 🇺🇸 or Canada 🇨🇦 and thinking of doing research in Europe? ERC grants offer up to €4.5 million to support groundbreaking, investigator-driven frontier research in all fields. Watch the dedicated info session for researchers in your region👉 youtu.be/92QYink1Lik #ChooseEurope

Today, the ERC formally adopted a decision to increase its support for researchers moving to Europe. On top of its normal grants, the ERC offers 'start-up' funding to help PIs establish laboratories / research teams in Europe. This extra funding is now x2 (up to €2 million!) europa.eu/!6Vdgmp

Astronomer thinking of moving? Join me at Paris-Saclay (France) to work on multi-messenger astrophysics at the highest energies, the Astro-COLIBRI platform and citizen science.
