Overmerging describes the numerical or physical disruption of dark matter halos within dense environments. This problem was inherent in simulations prior to 1998 but can be completely overcome with current algorithms and hardware. We can now resolve many thousands of subhalos within clusters and we may have converged on their inner structure, allowing several new tests of the hierarchical structure formation model and the nature of dark matter.", "revisions": [ { "version": "v1", "updated": "2000-09-15T13:29:37.000Z" } ], "analyses": { "keywords": [ "brief history", "simulating clusters", "dark matter halos", "overmerging", "hierarchical structure formation model" ], "tags": [ "review article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 547584 } } }
