WebJul 27, 2024 · Using Planck 2024 CMB (TT+TE+EE+lensing) alone, best fits predict those parameters to be almost identical to ΛCDM, with slightly smaller χ 2min. The resulting H0 =72.24 ± 0.64 km/s/Mpc, which virtually alleviates the tension with local measurements, due to late time phantom behaviour. WebPotential small-scale discrepancies in the picture of galaxy formation painted by the ΛCDM paradigm have led to considerations of modified dark matter models. One such dark matter model that has recently attracted much attention is fuzzy dark matter (FDM) . Webflow) is a severe challenge to the standard ΛCDM paradigm and has fundamental implications on the topology of the universe, the inflationary scenario and the nature of gravity (e.g. Carroll et al. 2008; Afshordi et al. 2009; ... even an uniform dark flow can induce small angular scale temperature fluctuations in the CMB sky, through exactly 400比特币多少钱
