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: The Galaxy And Mass Assembly (GAMA) survey as mentioned in this paper is one of the largest contemporary spectroscopic surveys of low redshift galaxies, covering an area of ∼286 deg2 (split among five survey regions) down to a limiting magnitude of r < 19.8 mag, and collecting spectra and reliable redshifts for 238'000 objects using the AAOmega spectrograph on the Anglo-Australian Telescope.

TL;DR: The Galaxy And Mass Assembly (GAMA) survey is a multi-wavelength photometric and spectroscopic survey, using the AAOmega spectrograph on the Anglo-Australian Telescope to obtain spectra for up to ∼300 000 galaxies over 280 deg2, to a limiting magnitude of rpet < 19.8 mag as discussed by the authors.

TL;DR: In this paper, it was shown that the decrease in Phi at bright luminosities is best described by a Saunders functional form rather than the traditional Schechter function, which is consistent with other published luminosity functions in the far-infrared and radio.

TL;DR: In this article, radio Active Galactic Nuclei (AGN) luminosity functions over the redshift range 0.005 < z < 0.75 were derived from matched Faint Images of the Radio Sky at Twenty-cm survey (FIRST) sources and Sloan Digital Sky Survey (SDSS) images.
