The Universe of A.D. Sakharov at ECU2021

New postby Maxim Khlopov on Fri 19 Feb 2021 22:35

On 24 February 2021 in the framework of 1 Electronic Conference on Universe (ECU2021)
will be held Live Session 8 “The Universe of Andrei Sakharov”
In 2021, we will commemorate the 100th anniversary of the birth of Andrei D. Sakahrov, and UNESCO has nominated this year A.D. Sakharov year. The paper "Cosmoparticle Physics as Cross-Disciplinary Science" was the last in the list of Sakharov's publications, so studies of the fundamental relationship of cosmology and particle physics further developed his scientific legacy.

Sakharov conditions in baryosynthesis, Sakharov oscillations in CMB, and Sakharov enhancement in dark matter annihilation are but a few examples of A.D. Sakharov’s legacy in the modern theory of the Universe. The aim of this session is to discuss the place and prospects of the development of Sakharov's legacy in studies of the mutual relationship of the bases of modern particle physics and cosmology, as well as the nontrivial features of its indirect physical, cosmological, and astrophysical probes. Such features involve but are not limited to models of the very early Universe and their observational signatures, physics of dark matter, and its direct and indirect probes, as well as to a wide range of models beyond the standard models of particle physics and cosmology and their effects.

The live session was held in form of Satellite Workshop
