The Galaxy And Mass Assembly (GAMA) structural decomposition pipeline (GAMA-SIGMA; Structural Investigation of Galaxies via Model Analysis) will provide multi-component information for a sample of ∼12,000 galaxies across 9 bands ranging from near-UV to near-IR. This will allow the relationship between structural properties and broadband, optical-to-near-IR, spectral energy distributions of bulge, bar, and disk components to be explored, revealing clues as to the history of baryonic mass assembly within a hierarchical clustering framework. Data is initially taken from the SDSS & UKIDSS-LAS surveys to test the robustness of our automated decomposition pipeline. This will eventually be replaced with the forthcoming higher-resolution VST & VISTA surveys data, expanding the sample to ∼30,000 galaxies. [ABSTRACT FROM AUTHOR]
