Abstract

The 4MOST Hemisphere Survey (4HS) will obtain uniform spectroscopy and redshifts for approximately six million galaxies over ~ 2π steradians, and with high and unbiased completeness for z < 0.15. 4HS aims to 1) complete the map of mass and motion in the Local Volume, 2) map the influence of environment on galaxy evolution through overwhelming statistics, and 3) define the local (z < 0.15) galaxy reference sample for the era of LSST, Euclid, and ASKAP/MeerKAT/SKA. The result is a dataset with exceptional and long-lasting legacy value.
