The GAMA Panchromatic Survey

TL;DR

The GAMA survey is a comprehensive, multi-wavelength spectroscopic campaign covering 300 square degrees, providing high-quality redshift data and extensive galaxy measurements across 27 wavebands for 380,000 galaxies.

Contribution

It introduces a uniform, flux-limited spectroscopic survey with multi-wavelength data integration, enabling detailed galaxy and structure analysis.

Findings

Over 225,000 redshifts collected, third largest after SDSS and BOSS.

Complete multi-wavelength coverage from UV to radio for 380,000 galaxies.

High-fidelity galaxy group and pair catalogues enabled by survey design.

Abstract

The Galaxy And Mass Assembly Survey (GAMA) has now been operating for almost 5 years gathering spectroscopic redshifts for five regions of sky spanning 300 sq degrees in total to a depth of r<19.8 mag. The survey has amassed over 225,000 redshifts making it the third largest redshift campaign after the SDSS and BOSS surveys. The survey has two novel features that set it apart: (1) complete and uniform sampling to a fixed flux limit (r<19.8 mag) regardless of galaxy clustering due to multiple-visits to each sky region, enabling the construction of high-fidelity catalogues of groups and pairs, (2) co-ordination with diverse imaging campaigns which together sample an extremely broad range along the electro-magnetic spectrum from the UV (GALEX) through optical (VST KIDs), near-IR (VISTA VIKING), mid-IR (WISE), far-IR (Herschel-Atlas), 1m (GMRT), and eventually 20cm continuum and rest-frame 21cm line measurements (ASKAP DINGO). Apart from the ASKAP campaign all multi-wavelength programmes are either complete or in the final stages of observations and the UV-far-IR data are expected to be fully merged by the end of 2013. This article provides a brief flavour of the coming panchromatic database which will eventually include measurements or upper-limits across 27 wavebands for 380,000 galaxies. GAMA DR2 is scheduled for the end of January 2013.
