The observed averaged value and variance of the Hubble constant are reproduced by adopting a rim model, an auto-gravitating model, and a Voronoi diagrams model as the backbone for an auto-gravitating medium. We also analyze an astronomer's model based on the 3D spatial distribution of galaxies as given by the 2MASS Redshift Survey and an auto-gravitating Lane--Emden ($n=5$) profile of the electrons. The simulation which involves the Voronoi diagrams is done in a cubic box with sides of 100 Mpc. The simulation which involves the 2MASS covers the range of redshift smaller than 0.05.", "revisions": [ { "version": "v1", "updated": "2014-09-29T12:45:35.000Z" } ], "analyses": { "keywords": [ "hubble constant", "density gradients", "anisotropy", "3d spatial distribution", "voronoi diagrams model" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 26, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1319271, "adsabs": "2014arXiv1409.8100Z" } } }
