In the canonical ensemble, the post-collapse evolution is marked by the formation of a Dirac peak with increasing mass. The density profile outside the peak evolves self-similarly with decreasing central density and increasing core radius. In the microcanonical ensemble, the post-collapse regime is marked by the formation of a ``binary''-like structure surrounded by an almost uniform halo with high temperature. These results are consistent with thermodynamical predictions.", "revisions": [ { "version": "v2", "updated": "2004-03-23T17:45:43.000Z" } ], "analyses": { "keywords": [ "self-gravitating brownian particles", "post-collapse dynamics", "dimensions", "high temperature", "uniform halo" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
