Head Zhdanov Valerii I., Доктор фізико-математичних наук Registration Date 27-02-2026 Organization Taras Shevchenko National University of Kyiv popup.description1 Determination of nature and identification of sources of ultrahigh energy cosmic rays (UHECR); improvement of models of relativistic objects taking into account the effects of “new physics”, which arise from the study of UHECR and their multimessenger manifestations in energy ranges beyond the standard theory. popup.description2 The project is dedicated to establishing the nature of ultrahigh-energy cosmic rays, in particular, the study of sources and mechanisms of their acceleration, the features of their propagation in intergalactic and galactic magnetic fields, based on the analysis of the aggregate data of multi-channel (multimessenger) astronomical observations, including observations of electromagnetic radiation, gravitational waves, cosmic ray fluxes and cosmogenic neutrinos. New and improved existing models of high-energy phenomena in astrophysical objects related to the generation and propagation of high- and ultrahigh-energy cosmic rays, multi-wave electromagnetic radiation will be developed. Experimental verification of new theoretical models of relativistic objects developed by the authors of the project within the framework of the general theory of relativity and its modifications using modern theories of fundamental interactions, including models of dark matter and dark energy, will be carried out. Special attention will be paid to research under the CTA program - the consortium (https://www.cta-observatory.org/about/cta-consortium), to which the authors of the proposed project belong, and to the practical application of the results - the development of a muon tomography technique for tasks of priority direction 38 Product Description popup.authors Alona M.
