Mapping the Universe Using Cosmic Neutrinos

Abstract

This article was inspired by the findings of the IceCube neutrino laboratory. The most recent findings show that the high energy neutrino background in the galactic plane could be caused by the galactic nucleus and is by a factor 1/100 too small to be produced by the interactions of high energy cosmic rays with very strong magnetic fields. The neutrino flux is so weak in the case of Earth that the Milky Way is described as a neutrino desert. Earlier discovery by IceCube of ultrahigh energy (UHE) cosmic neutrinos coming from galaxies TXS and NGC suggest that they originate from active galactic nuclei (AGNs). Unlike in the case of NGC, AGN is a quasar in the case of TXS so that its jet points toward the Earth. There are notable differences between these neutrino sources. In this article, a TGD based model for the sources of UHE neutrinos and for the neutrino propagation mechanisms is proposed. The model relies on a new view of space and on a general model of astrophysical objects inspired by the notion of cosmic strings as 4-D surfaces in M⁴ x CP₂ having 2-D string world sheet as M⁴ projection.
