Engineering Physics Annotation << Back THE MODULATED NEUTRINO STREAMS: ASTROPHYSICAL AND GEOPHYSICAL PERIODICITY O.B. KHAVROSHKIN, V.V. TSYPLAKOV Unaddressed existence of extraterrestrial sources of high energy neutrinos was discovered in 2013. But the most promising addition to supernovae includes objects such as pulsars and closes multiple systems. Relying mainly on its own experience in the search and registration of the seismic response at frequencies of pulsars and close binary stars on Earth and the Moon and using the results to detect solar neutrinos work on the study of modulated neutrino fl uxes were continued. The study of the spectra of lunar seismic noise revealed a number of signifi cant spectral peaks that match the frequency to 3-4 signifi cant fi gures with the frequencies of sending energy pulses from pulsars. At the same time availability of seismic peaks and their characteristics are strongly associated with the shape and depth of the radioactive geological structures of the lithosphere of the Moon. That is the energy of interaction modulated beam of neutrinos from the pulsar radioactive elements Moon differently converted into energy of seismic noise. There have also been recorded seismic peaks well coincides with the period of close binary stars. Some of the peaks previously registered not only as a purely seismic frequency, but as the frequency inherent to radioactive laboratory sources, which further confi rms their astrophysical neutrino origin and similarity search became part of high-energy neutrino astronomy. Key words: modulated neutrino streams, astrophysical sources of neutrinos, neutrino detection techniques, the antenna pattern of the neutrino. Contacts: E-mail: khavole@ifz.ru Pp. 27-47.
