TL;DR

The GAMA survey provides extensive spectroscopic and photometric data for over 120,000 galaxies, with detailed data processing, quality assessment, and public data releases to facilitate galaxy evolution studies.

Contribution

This paper details the survey design, data reduction, and release of comprehensive galaxy catalogues, including spectroscopic and photometric data, for the first three years of the GAMA project.

Findings

01

High redshift completeness (>98%) for targeted galaxies.

02

Public release includes data from the first year, covering specified magnitude limits.

03

Multiple data products and catalogues support diverse galaxy research.

Abstract

The Galaxy And Mass Assembly (GAMA) survey has been operating since February 2008 on the 3.9-m Anglo-Australian Telescope using the AAOmega fibre-fed spectrograph facility to acquire spectra with a resolution of R~1300 for 120,862 SDSS selected galaxies. The target catalogue constitutes three contiguous equatorial regions centred at 9h (G09), 12h (G12) and 14.5h (G15) each of 12 x 4 sq.deg to limiting fluxes of r < 19.4, r < 19.8, and r < 19.4 mag respectively (and additional limits at other wavelengths). Spectra and reliable redshifts have been acquired for over 98 per cent of the galaxies within these limits. Here we present the survey footprint, progression, data reduction, redshifting, re-redshifting, an assessment of data quality after 3 years, additional image analysis products (including ugrizYJHK photometry, Sersic profiles and photometric redshifts), observing mask, and…
