Astronomy with energy dependent flavour ratios of extragalactic neutrinos

نویسندگان

چکیده

High energy astrophysical neutrinos interacting with ultralight dark matter (DM) can undergo flavour oscillations that induce an dependence in the ratios. Such a on neutrino will reflect track to shower ratio telescopes like IceCube or KM3NeT. This opens up possibility study DM density profiles of objects AGN, GRB etc., which are suspected sources such neutrinos.

Extragalactic Stellar Astronomy

Despite their paucity, massive hot stars are real cosmic engines of fundamental importance in shaping our Universe, from its very early stages up to its current appearance. Understanding the physics of massive stars is then a key issue for many relevant astrophysical phenomena. Their spectra provide constraints required for stellar and galactic evolution calculations, such as mass-loss rates, d...

Neutrinos and Lepton - Flavour – Violation ∗

The standard model (SM) of particle physics successfully describes a variety of phenomena in terms of a few fundamental quantities. Besides the gauge coupling constants associated to the fundamental interactions, and the scalar sector responsible for spontaneous electroweak symmetry breaking, the major part of adjustable parameters are related to the fermion sector describing the masses and mix...

The Long–Term Future of Extragalactic Astronomy

If the current energy density of the universe is indeed dominated by a cosmological constant, then high–redshift sources will remain visible to us only until they reach some finite age in their rest–frame. The radiation emitted beyond that age will never reach us due to the acceleration of the cosmic expansion rate, and so we will never know what these sources look like as they become older. As...

Multivariate approaches to classification in extragalactic astronomy

Clustering objects into synthetic groups is a natural activity of any science. Astrophysics is not an exception and is now facing a deluge of data. For galaxies, the one-century old Hubble classification and the Hubble tuning fork are still largely in use, together with numerous monoor bivariate classifications most often made by eye. However, a classification must be driven by the data, and so...

Flavour-conserving oscillations of Dirac-Majorana neutrinos

We analyze both chirality-changing and chirality-preserving transitions of DiracMajorana neutrinos. In vacuum, the first ones are suppressed with respect to the others due to helicity conservation and the interactions with a (“normal”) medium practically does not affect the expressions of the probabilities for these transitions, even if the amplitudes of oscillations slightly change. For usual ...
