Ultra - Transparent Antarctic Ice as a Supernova
نویسندگان
چکیده
We have simulated the response of a high energy neutrino telescope in deep Antarctic ice to the stream of low energy neutrinos produced by a supernova. The passage of a large ux of MeV-energy neutrinos during a period of seconds will be detected as an excess of single counting rates in all individual optical modules. We update here a previous estimate of the performance of such an instrument taking into account the recent discovery of absorption lengths of several hundred meters for near-UV photons in natural deep ice. The existing AMANDA detector can, even by the most conservative estimates, act as a galactic supernova watch.

Footprints of the Newly - Discovered Vela Supernova in Antarctic Ice Cores ?
The recently-discovered, nearby young supernova remnant in the southeast corner of the older Vela supernova remnant may have been seen in measurements of nitrate abundances in Antarctic ice cores. Such an interpretation of this twenty-year-old ice-core data would provide a more accurate dating of this supernova than is possible purely using astrophysical techniques. The resulting estimates of t...

متن کاملLight tracking through ice and water – Scattering and absorption in heterogeneous media with PHOTONICS
In the field of neutrino astronomy, large volumes of optically transparent matter like glacial ice, lake water, or deep ocean water are used as detector media. Elementary particle interactions are studied using in situ detectors recording time distributions and fluxes of the faint photon fields of Cherenkov radiation generated by ultra-relativistic charged particles, typically muons or electron...
متن کاملLight tracking for glaciers and oceans – Scattering and absorption in heterogeneous media with PHOTONICS
In the field of neutrino astronomy, glacial ice or deep ocean water are used as detector medium. Elementary particle interactions are studied using in situ detectors recording time distributions and fluxes of the faint photon fields of Cherenkov radiation, typically generated by ultra-relativistic muons. The Photonics software package was developed to determine photon flux and time distribution...
