large-scale structure of Universe
Abstract:
Peculiar velocities arise from gravitational instability, and thus
are linked to the surrounding distribution of matter. In order to
understand the motion of the Local Group with respect to the cosmic
microwave background, a deep all-sky map of the galaxy distribution
is required. Here we present a new redshift compilation of 69160
galaxies, dubbed 2M++, to map large-scale structures of the local
Universe over nearly the whole sky, and reaching depths of K<=12.5,
or 200h^-1^Mpc. The target catalogue is based on the Two-Micron
All-Sky Survey Extended Source Catalog (2MASS-XSC). The primary
sources of redshifts are the 2MASS Redshift Survey, the 6dF galaxy
redshift survey and the Sloan Digital Sky Survey (Data Release 7).
We assess redshift completeness in each region and compute the weights
required to correct for redshift incompleteness and apparent magnitude
limits, and discuss corrections for incompleteness in the zone of
avoidance. We present the density field for this survey, and discuss
the importance of large-scale structures such as the Shapley
Concentration.

Note (1): We define as K2M++ (K2mag) the magnitude of a galaxy measured in
the K_S_ band, within the circular isophote at 20mag/arcsec^2^, after
various corrections described in Section 2.2. The magnitude is derived
from the 2M++ galaxies. This is a magnitude uncorrected for
incompleteness effect.
