Abstract (from CDS):

We present the reconstructed real-space density and the predicted velocity fields from the Two-Micron All-Sky Redshift Survey (2MRS). The 2MRS is the densest all-sky redshift survey to date and includes about 23200 galaxies with extinction-corrected magnitudes brighter than Ks= 11.25. Our method is based on the expansion of these fields in Fourier-Bessel functions. Within this framework, the linear redshift distortions only affect the density field in the radial direction and can easily be deconvolved using a distortion matrix. Moreover, in this coordinate system, the velocity field is related to the density field by a simple linear transformation. The shot noise errors in the reconstructions are suppressed by means of a Wiener filter which yields a minimum variance estimate of the density and velocity fields. Using the reconstructed real-space density fields, we identify all major superclusters and voids. At 50 h–1 Mpc, our reconstructed velocity field indicates a backside infall to the Great Attractor region of vinfall= (491 ±200) (β/0.5)km/s in the Local Group frame and vinfall= (64±205) (β/0.5)km/s in the cosmic microwave background (CMB) frame and β is the redshift distortion parameter. The direction of the reconstructed dipole agrees well with the dipole derived by Erdo{gbreve}du et al. The misalignment between the reconstructed 2MRS and the CMB dipoles drops to 13° at around 5000 km/s but then increases at larger distances.
