An optimal cross-correlation appears to be a stable solution, and finds a twist angle of close to +36 degrees. * ArXiv:0801.0006, ArXiv:0807.4260 - consistent with Luminet et al./Caillerie et al. and Aurich et al. analyses Three-torus CMB + 3D quadruples methods: * ArXiv:1302.4425 - Deep redshift topological lensing: strategies for the T^3 candidate - [[http://mnras.oxfordjournals.org/cgi/content/abstract/stt1885?ijkey=Uj5aMs4psAuEo85&keytype=ref][MNRAS URL]] - Roukema, France, Kazimierczak, Buchert (2013) ---++ theoretical work The Poincare dodecahedral space is much better balanced, in the sense of the interaction between topology and gravity called the residual gravity effect, than other spaces. * AstroPh:0602159, ArXiv:0902.3402 - the residual gravity acceleration effect * [1] http://cdsads.u-strasbg.fr/abs/2007A%26A...463..861R * [2] http://cdsads.u-strasbg.fr/abs/2009A%26A...502...27R * [3] http://cdsads.u-strasbg.fr/abs/2012CQGra..29p5006O ---++ people People in our group presently working on cosmic topology subjects include: * Main.BoudRoukema * Zbyszek Bulinski * Main.TomaszKazimierczak ([[http://epsrv.astro.uni.torun.pl/~chudy/licencjat.html][Testowanie modelu Przestrzeni Dwunastościennej Poincare jako topologicznego modelu Wszechświata]]) ---++ older work * WMAP - identified circles - MonographCosmo * AstroPh:0402608 * however: see AstroPh:0604616, ArXiv:0801.1358, ArXiv:0801.0006 * [[%ATTACHURL%/../CosmoProjects/mhg_20050330.ps][mhg_20050615.ps]]: Calabretta & Roukema, draft - http://www.atnf.csiro.au/people/mcalabre/WCS/index.html * RLAGNs larger catalogue/histograms - Boud, Andrzej M, Staszek - mrb04 * AstroPh:0412181 * root of the identity in the spherical case - Boud * AstroPh:0409694 ---++ press releases * PressReleaseRBSG08 * MediaShapeUniverse * OswiadczeniePrasoweDodekahedron ---++ courses that include some cosmic topology content * MonographCosmo -- Main.BoudRoukema - 14 Jul 2010
