When a neutrino very, very, very, very, very rarely hits an atomic nucleus in the ice, it produces a cone of blue light called Cerenkov radiation that spreads through the ice and is picked up by the photomultipliers.

This "Cerenkov" light is the focus of instruments such as , or the telescope.

"The idea is to have some sort of bridge catalogue between the typical catalogue done by Fermi... which contains thousands of sources, and the domain of the Cerenkov telescopes that have been operating over 20 years," lead author of the new catalogue, David Paneque of the Max Planck Institute for Physics in Munich, Germany, told BBC News.

The same has also been done with another large array telescope called the Cerenkov Large Array telescope that marshals the same detector used in galactic neutrino and proton-related observations to look at non-thermal high energy particles that could be the window to these invisible entities, and thus, a view into the genesis of our universe.

Transition Radiation Detector determines highest-energy particle velocities Silicon trackers follow particle paths; how they bend reveals their charge Permanent magnet is core component of AMS and makes particles curve Time-of-flight counters determine lowest-energy particle velocities Star trackers scan star fields to establish AMS's orientation in space Cerenkov detector makes accurate velocity measurements of fast particles Electromagnetic calorimeter measures energy of impacting particles Anti-coincidence counter filters signal from unwanted side particles AMS does carry a magnet - a very big one.
