Local gravity versus local velocity: solutions for β and non-linear bias
Local gravity versus local velocity: solutions for β and non-linear bias
(abridged) We perform a reconstruction of the cosmological large scale flows in the nearby Universe using two complementary observational sets. The first, the SFI++ sample of Tully-Fisher (TF) measurements of galaxies, provides a direct probe of the flows. The second, the whole sky distribution of galaxies in the 2MASS redshift …
