Description
The diffused light between galaxies, as first discovered by
Zwicky (1951), has been an interesting issue related with the
evolution of galaxies. N-body simulations of
mergers of galaxies with dark matter have been employed to address
this topic. By N-body simulations, we investigate the production of
intergalactic populations through head-on mergers. Our results
show that single head-on mergers cannot explain the observations,
and the main conclusions are:
(1)head-on merging events make a considerable fraction of dark metter
become unbound;
(2)some luminous intergalactic populations are in fact trapped in dark halo
and gravitationally bounded;
(3)multiple and minor mergers shall have contributions on
intergalactic populations.
