<< Cosmo.WebHome %TOC% ---- %INCLUDE{"GrassmannCosmoFun2009Head"}% ---+ Thu 17 Sep 2009 ---++ Nemanja KALOPER - inflaton etc * inflaton difficult but not impossible to obtain * T^4, topological mass term ... ---++ Arman SHAFIELOO - Is cosmic acceleration slowing down? * 90 new low z < 0.08 SNe Ia data from CfA * OM fittings, SN+BAO vs SN+BAO+WMAP gives %$ \Delta \chi^2 \approx 8 $% * ArXiv:0903.5141 * OM behaviour at low z * can be derived directly from H rather than dot(H) * errors in OM smaller than for EOS * OM not sensitive to Omega_m * CPL parametrisation strains to fit low z and high z data simultaneously ---++ Masahiro MORIKAWA - Bose-Einstein condensate DE/DM (BEC) * AstroPh:0403571 * boson field * What is the boson? axion? neutrino pair condensation? new physics? * if m = 1 eV, then BEC collapses to form objects of size l* approx 30(m/1eV)^2 kpc * if BEC decays at z = 20, this gives about 20 kpc * predicts stagflation which dissipatively reduces Lambda to zero ---++ Mikhail KATANAEV - geometric theory of defects * edge dislocation - in elastic media - Burger's vector * disclinations - in spin structures * geometric model vs elasticity model ---++ Marek SZYDLOWSKI - whirlpool scenario * flat model * ArXiv:0906.0335 * 3D phase space trajectory matches different evolution stages of Universe, i.e. radiation, dust and accelerating epochs ---++ Ivan DEBONO - weak lensing forecasts for DE, neutrinos and initial conditions * modelling of local cosmological parameters * lensing can be useful * need to: minimise "systematics in lensing", more accurate theoretical power spectrum calculation, combining different experiments is always better ---++ Stefano CAMERA (Turino) - weak lensing in unified DM/DE models * ArXiv:0902.4204 * would have some effect on weak lensing via a high l effect ---++ Boud ROUKEMA - Some spaces are more equal than others * AstroPh:0602159 + ArXiv:0902.3402 (summary: ArXiv:0905.2543) -- Main.BoudRoukema - 17 Sep 2009
