Downsizing from the point of view of merging model (preliminary discussion)
arXiv:1507.00192
Abstract
In four-particle scattering processes with transfer of mass, unlike mergers in which mass can only increase, mass of the most massive galaxies may be reduced. Elementary model describing such process is considered. In this way, it is supposed to explain observed phenomenon of downsizing when increasing of characteristic mass the heaviest galaxies over cosmological time replaces by its reduction.
