TL;DR: The Galaxy and Mass Assembly (GAMA) survey has been operating since 2008 February on the 3.9m Anglo-Australian Telescope using the AAOmega fibre-fed spectrograph facility to acquire spectra with a resolution of R ≈ 1300 for 120 862 Sloan Digital Sky Survey selected galaxies.

TL;DR: Using the complete Galaxy and Mass Assembly I (GAMA-I) survey covering ∼142 deg2 to rAB= 194, of which ∼47 deg2 is to RAB= 198, the G3Cv1 catalogue as mentioned in this paper was created using a friends-of-friends (FoF) based grouping algorithm.

TL;DR: In this article, the authors measured the high-mass initial mass function slope for a sample of low-to-moderate redshift galaxies from the Galaxy and Mass Assembly survey and found that highly star-forming galaxies form proportionally more massive stars than galaxies with low star formation rates.
