Abstract: Neutrinos heavier than $M_Z/2\sim 45$ GeV are not excluded by particle
physics data. Stable neutrinos heavier than this might contribute to the dark

Cherenkov Flashes and Fluorescence Flares on Telescopes: New lights on UHECR Spectroscopy while unveiling Neutrinos Astronomy. (arXiv:0710.3805v1 [astro-ph]) -

Cherenkov Telescopes (as Magic, Hess and Veritas), while pointing
horizontally should reveal also the fluorescence flare tails of nearby
down-going air-showers. Such air-showers, born at higher (tens km) altitudes,
are growing and extending up to lowest atmospheres (EeVs) or up to higher (few
km) quotas (PeVs). Viceversa, as it has been foreseen and only recently
