KM3NeT neutrino telescope
@km3net.bsky.social
KM3NeT is a neutrino telescope with two detectors - ARCA and ORCA - at the bottom of the Mediterranean Sea. It is also an international consortium of research institutes and university groups collaborating to operate the two detectors - www.km3net.org
A new #KM3NeT laboratory, INTEGRA (INTEGration & Research Area), is inaugurated today in Salerno!
It is dedicated to assemble and test KM3NeT Optical Modules to speed up even more the growth of our #neutrino detector📈
Made possible by: #UniversityOfSalerno #INFN #KM3NeT4RR #PNRR #NextGenerationEU

Five days of great discussions at #CERN on #ARCA & #ORCA progress: from #dataanalysis and #detector systematics to #astrophysics and #darkmatter!
Hands-on sessions, new ideas, and a fantastic visit to CERN’s Neutrino Platform.
Thanks to the organisers, see you in Valencia in January!

🛥️ Welcome ORCA33! 🌞
We had a new successful sea campaign:
1) We reconnected 4 lines previously installed and tested on node 1 to the newly deployed node 2
2) We deployed and connected 5 new lines to node 2
Big thanks to everyone involved for this great step!

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!

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
