We review the previous studies of the loss-cone problem and present a novel simulation method which allows to separate out the collisional (relaxation-related) and collisionless (related to non-conservation of angular momentum) processes and determine their relative importance for the capture rates in different geometries. We show that for black holes more massive than 10^7 Msun, the enhancement of capture rate in non-spherical galaxies is substantial, with even modest triaxiality being capable of keeping the capture rate at the level of few percent of black hole mass per Hubble time.", "revisions": [ { "version": "v1", "updated": "2014-11-06T21:00:10.000Z" } ], "analyses": { "keywords": [ "supermassive black holes", "non-spherical galactic nuclei", "capture rate", "novel simulation method", "black hole mass" ], "tags": [ "journal article" ], "publication": { "doi": "10.1088/0264-9381/31/24/244002", "journal": "Classical and Quantum Gravity", "year": 2014, "month": "Dec", "volume": 31, "number": 24, "pages": 244002 }, "note": { "typesetting": "TeX", "pages": 21, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014CQGra..31x4002V" } } }
