Тема семинара: «Antiworlds and primordial black holes»
Докладчик: Александр Долгов
The recent data by James Webb Space Telescope and Hubble Space Telescope on the early universe are reviewed. It is argued that the tension between the data and the conventional Lambda-CDM cosmology is relaxed if the universe is populated by primordial black holes (PBH). Other implications of PBH are discussed, in particular, for the gravitational waves observed by LIGO/Virgo/Kagra.
The proposed mechanism of PBH formation could lead to a noticeable population of the Galaxy with antimatter. The observational evidence in favor of this conclusion and some observational tests are considered.
