Sara, Sriya, Adrian, Jorge, Ricardo and Guille participated in this year's IFIC Summer School, where they taught students Sergi, María, Belén and Pablo how to perform various analyses in @km3net.bsky.social

🚀 At ICRC in Geneva, KM3NeT shared exciting new results in neutrino, astro & dark matter physics, including #KM3230213A, the most energetic neutrino ever detected! 🌌 We also joined CERN’s STELLAR event for public outreach. More: lnkd.in/eB3M88gF #KM3NeT #ICRC2025 #Astrophysics

VEGA has been these two weeks contributing to the large amount of interesting state of the art contributions of the ICRC 2025 with ours from ANTARES & @km3net.bsky.social with more than 5 talks and 7 posters! Looking forward for ICRC 2027 at Buenos Aires and ICRC 2029 at Jinan!

Beautiful pictures in the corridors of @nikhef.bsky.social

Over the past two weeks, a record number of 18 new detection units for the @km3net.bsky.social neutrino detector have been installed on the seabed off the coast of Sicily and connected to the data networks on land. www.nikhef.nl/en/news/reco...

🚢🌊 Welcome, ARCA51! A milestone for KM3NeT! 🚢🌊 In the past 2 weeks, KM3NeT/ARCA grew to 51 detection units and got a new acoustic system with sub-meter precision 🎯 👏 Huge thanks to our offshore & onshore teams! More details here: lnkd.in/euUAg-f4 #KM3NeT #ARCA51 #Neutrino

Kicking off your week with some great news? More updates will follow soon! #staytuned

We are very proud of our PhD student Nadja Lessing from @vegaific.bsky.social! She won the @europhysicssociety.bsky.social poster prize at the Majorana School held in Modica (Sicily, Italy)! 👏👏👏 On her poster she shows how KM3neT can search for quantum decoherence Have a look and get inspired!

🌌 KM3NeT at #EPSHEP2025 🌌 At the #EPS #HEP #conference (the High-Energy Physics division of @europhysicssociety.bsky.social), KM3NeT participated with 5 parallel talks as well as a plenary talk It was well appreciated, and nice to share knowledge across communities #astrophysics 🩵 #particlepysics

We love the sunset above the Mediterranean Sea Seen from our ARCA control station in Portopalo di Capo Passero in Sicily, Italy 😍 #KM3NeT

In a new #KM3NeT paper we show that the flux of atmospheric muon-neutrinos in the ORCA6 detector is in agreement with the HKKM14 model and with the values measured by other experiments. It is a promise for more precise measurements with more detection units in ORCA. www.km3net.org/atmospheric-...

Last week in Brussels our funding authorities signed an agreement establishing the #KM3NeT AISBL Serious stuff! The #AISBL provides us with a formal and internationally recognised legal entity as a non-profit organisation building, operating and exploiting the KM3NeT observatory Important!

Last week, our Collaboration met in Caen for our summer meeting, with great talks on ARCA & ORCA detector progress,calibration,simulation and analysis. Welcome to new members: Princeton (full),TU Munich,NTNU & UNESP (observers)! Thanks @lpccaen.bsky.social for hosting us. See you in October at CERN!

🌈 During #PrideMonth, we honour the 1969 Stonewall riots and the fight for #LGBTQIA+ rights. We celebrate diversity, inclusion, and the courage of those who stood for equality. As a research collaboration, we believe science must be open to all, regardless of identity or orientation. 💡🌊

Happy anniversary #nikhef50! Today we congratulate @nikhef.bsky.social with its 50th anniversary. Nikhef is a founding partner of #KM3NeT. It is the lab where our multi-PMT optical module was born. Thanks for all your valuable contributions to #KM3NeT. We wish you a splendid anniversary week!

Four months ago we published the exciting #KM3NeT_UHE #RecordNeutrino #KM3230213A in @nature.com The scientific community is eagerly working on understanding this observation. Beside our 5 companion papers, almost 30 papers have been published in a broad range of topics: arxiv.org/search/?quer...

A new #KM3NeT paper! About how, in real time, we filter our raw data. The design of the filter, its purity or how well background is removed, the computing capacity needed, its efficiency in terms of effective detector volume. It is all explained in www.km3net.org/the-online-d... Enjoy reading!

How are KM3NeT’s #OpticalModules built? It’s an elaborate, multi-step process! Last week, our collaborators met at the new #CAPACITY lab in #Caserta for the 2nd Optical Module Integration Workshop to assemble, test, and share best practices. #KM3NeT More info: www.km3net.org/2nd-dom-inte...

WELCOME ORCA28! 🎉 A sea operation was performed this week, with a twofold purpose: the recovery from the sea bottom of some oceanographic instruments which require maintenance and the installation of 4 new detection units!

In KM3NeT, we use light to "see the invisible". This display shows #KM3230213A, our ultra-high-energy neutrino. Each sphere shows #Cherenkov #light detected deep under the sea, with colours representing when the light arrived. #InternationalDayOfLight #KM3NeT

Europe day was a week ago, but for us it's Europe day everyday! We're happy that our #RecordNeutrino has been featured by the @erc.europa.eu in #CORDIS_eu: cordis.europa.eu/article/id/4... #EUresearchResults #INFRADEV2 #MuSES #MessMapp #UNOS #ChETEC-#INFRA Thanks, and on to the next big result! ✨
