Description
The Trinity Neutrino Observatory is designed to detect tau neutrinos in the 1 PeV–10 EeV range by observing Cherenkov emission from extensive air showers following the decay of a tau emerging from the Earth. By bridging the gap between water/ice optical Cherenkov detectors and radio-based experiments, Trinity probes the poorly explored transition region between astrophysical and cosmogenic neutrinos.
The first phase of the project, the Trinity Demonstrator at Frisco Peak in Utah, was commissioned in 2024 and has since performed regular observations. Analysis results from more than one year of observations are presented here. These results characterize the instrument's performance and validate the path towards Trinity One, the first full-scale telescope.
With an effective collection area 16 times larger than that of the demonstrator, Trinity One will already achieve competitive sensitivities. Its azimuthal rotation capability will enable point-source searches over half of the sky, as well as follow ups of transient multi-messenger events. Updated performance projections are presented, and detection prospects are evaluated across a range of source classes.
