SNO+ has been taking data with a pure water detector since May 2017.  Results have recently been published in Physical Review D for a very low background measurement of solar neutrinos (https://arxiv.org/abs/1812.03355) and a search for a special kind of nucleon decay that would indicate new physics beyond the Standard Model (https://arxiv.org/abs/1812.05552). 

Zach studied how supernova neutrinos could interact in the DUNE detector and also made predictions for interactions in a small prototype.  Job well done, Zach! 

Because beer tastes better with neutrinos.

The SNO+ detector, recently filled with ultra pure water, is searching for neutrons that spontaneously decay into three neutrinos.  The neutrinos coming from this decay would leave the detector undisturbed (they're invisible to us).  However, the disappearance of the neutron from an oxygen nucleus will often emit several gamma rays, which would readily be seen inside SNO+.  This special type of nucleon decay is one of the dominant modes predicted by particle physics models with Universal Extra Dimensions.

After years of hard work by many people, the SNO+ detector comes to life.  This is a 3D map of all the photomultiplier tubes in SNO+.  The colors indicate how many photons were seen by each photomultiplier (red = high, blue = low).  A ring-shaped image, like the one recorded here, is typically produced when a neutrino from the atmosphere interacts in the water-filled volume of the detector.
