| Abstract: |
The GAMA survey has now completed its spectroscopic campaign of over 250,000 galaxies (r<19.8 mag), and will shortly complete the assimilation of the complementary panchromatic imaging data from GALEX, VST, VISTA, WISE, and Herschel. In the coming years the GAMA fields will be observed by the Australian Square Kilometer Array Pathfinder allowing a complete study of the stellar, dust, and gas mass constituents of galaxies within the low-z Universe (z<0.3). The science directive is to study the distribution of mass, energy, and structure on kpc-Mpc scales over a 3 billion year timeline. This is being pursued both as an empirical study in its own right, as well as providing a benchmark resource against which the outputs from numerical simulations can be compared. GAMA has three particularly compelling aspects which set it apart: completeness, selection, and panchromatic coverage. The very high redshift completeness (∼ 98%) allows for extremely complete and robust pair and group catalogs; the simple selection (r<19.8 mag) minimizes the selection bias and simplifies its management; and the panchromatic coverage, 0.2 μm - 1 m, enables studies of the complete energy distributions for individual galaxies, well defined sub-samples, and population assembles (either directly or via stacking techniques).
