LZ, XENONnT and @XLZDcollab talking about dark matter in downtown Zurich!
Happy Dark Matter Day! 🌌🔍🎉
📣The group at @UZH_ch spent their day doing outreach in the wild. They chatted dark matter with passers by and did some radiation demos right in the center of town!

Excellent news regarding the Nobel Prize in Literature - Anne Carson is one of my favourite poets! Here from her book “If Not, Winter: Fragments of Sappho”
"stars around the beautiful moon
hide back their luminous form
whenever all full she shines
on the earth
silvery"

Since it came online in 2010, @uw_icecube has been covered extensively in @PhysicsToday. In 2013 it was discussed in relation to the search for hypothetical WIMPs—weakly interacting massive particles.

Amazing news for neutrinos and I am very happy for Francis and for the IceCube collaboration!
IceCube Principal Investigator and @UWMadison Prof. Francis Halzen has been awarded the 2026 Nobel Prize in Physics "for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin.” 🎉🏅

I am so happy today for Francis Halzen and for the IceCube collaboration. The Nobel Prize for Francis, for IceCube, and for high-energy neutrino astronomy is very special for me, both scientifically and personally.

Also, part of what makes today so special is the fact that the prize recognises not only a major discovery, but also the vision, persistence and courage needed to build such a large detector, and to create an entirely new way of observing the universe.

Finally, needless to say, I am also very happy for neutrino physics today. To me, neutrinos are both difficult and endlessly fascinating. There are still so many open questions that we are trying to answer by observing the elusive neutrinos :-)

Happy birthday to Alexander von Humboldt! A man who warned about harmful human-induced climate change more than 200 years ago. We clearly didn’t listen.

Good thread on potential background sources for the high-energy nuclear recoil event in LZ (none identified so far)
What are the backgrounds for our event of interest LZ230616, and why can't they currently explain it? 🤔 A thread: 🧵

Happy to be back in Geneva for the APPEC Town meeting which started this morning at Campus Biotech. The meeting aims to finalize the input for the 2027-2036 roadmap in astroparticle physics indico.cern.ch/event/1648605/…

We are very happy about this result with XENONnT. As Koshiba-san said many years ago, after he had proposed to observe solar neutrinos in Kamiokande, which started as a proton decay experiment: "Only people who prepared for them were able to observe them."
The XENONnT experiment, in its hunt for dark matter, has detected the rare, feeble glow of neutrinos smacking into electrons

With XENONnT we observed solar pp neutrinos via ν-e scattering. With an exposure of 2.46 t x y and electron recoil energies from 1 keV to 140 keV (probing neutrinos with energies down to 17 keV), the measured flux is (10.2±2.0)x10^10 cm^-2 s^-1. Μore at: arxiv.org/abs/2608.29450

Earlier this month in A Coruña, on the Monday before the total solar eclipse, Kajita-san gave a nice talk on lessons learned from Kamiokande and from Super-K: indico.cern.ch/event/1561367/… Here are some of the most relevant lessons:

1) Crazy ideas are important 2) Kamiokande started as proton-decay experiment, then observed solar and later also SN neutrinos 3) Expertise from two collaborations was needed for the success of Super-K 4) The background (neutrinos) became an important signal for Super-K

5) It is important to believe in experimental data without any bias 6) Interactions between theoretical and experimental physicists are very important 7) Sometimes basic research takes time (lesson for funding agencies!)

Do not miss this event :-)
The Xenon Collaboration is excited to announce that it will be hosting a LIVE presentation on Monday, August 31 at 10:00am EST about new findings from the XENONnT experiment.
