Quasar evolution via dark halo merger

Science in China Series A: Mathematics Aims and scope Submit manuscript

Abstract

Imaging surveys indicate that galaxy interaction or merging plays an important role in triggering the quasar phenomenon. It is assumed that a luminous quasar is created in the center of a merger of virialized dark matter halos. The abundance and evolution of quasars are computed in the cold dark matter models. The comparison between observational data and model predictions is presented.
