Further progress will come from a combination of parallax, proper motion and kinematic distance data via surveys using Southern Hemisphere — based radio telescopes as well as from space - based data from the European Space Agency's Gaia satellite.
Examples of science projects enabled by the data in the High - Latitude Survey include: mapping the formation of cosmic structure in the first billion years after the Big Bang via the detection and characterization of over 10,000 galaxies at z > 8; finding over 2,000 QSOs at z > 7; quantifying the distribution of dark matter on intermediate and large scales through lensing in clusters and in the field; identifying the most extreme star - forming galaxies and shock - dominated systems at 1 < z < 2; carrying out a complete census of star - forming galaxies and the faint end of the QSO luminosity function at z ~ 2, including their contribution to the ionizing radiation; and determining the kinematics of stellar streams in the Local Group through proper motions.
