Statistical analysis of the probability of globular clusters interactions with each other and with the galactic centre according to Gaia DR2 data on the cosmological time scale

Ishchenko, M.; Sobolenko, M.; Berczik, P. +1 more

The main idea of the work is to study the dynamic evolution of the orbits of globular clusters (GCs) lookback in time obtained from the cosmological models that are closest to the potential of the Galaxy. This allows us to estimate the probability of close passages ("collisions") of the GC with each other and with the Galactic central in the Galax…
