This observing program has been designed to overcome some of the limitations of other rotation curve studies that rely mostly on longslit spectra. We find that these objects exhibit the full range of central density profiles between constant density and NFW halos. This result suggests that there is a distribution of central density slopes rather than a unique halo density profile.", "revisions": [ { "version": "v1", "updated": "2003-11-11T21:04:44.000Z" } ], "analyses": { "keywords": [ "high resolution observations", "dark matter halo density profiles", "central density", "rotation curve", "nearby dwarf galaxies" ], "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "inspire": 633077 } } }
