Galaxy And Mass Assembly (GAMA): Galaxies at the faint end of the Halpha luminosity function
S. Brough, A. M. Hopkins, R. G. Sharp +30
We present an analysis of the properties of the lowest Halpha-luminosity galaxies (L_Halpha<4x10^32 W; SFR<0.02 Msun/yr) in the Galaxy And Mass Assembly (GAMA) survey. These galaxi…
Which halos host Herschel-ATLAS galaxies in the local Universe?
Qi Guo, Shaun Cole, Cedric G. Lacey +40
We measure the projected cross-correlation between low redshift (z < 0.5) far-IR selected galaxies in the SDP field of the Herschel-ATLAS (H-ATLAS) survey and optically selected ga…
Galaxy and Mass Assembly (GAMA): Dust obscuration in galaxies and their recent star formation histories
D. B. Wijesinghe, A. M. Hopkins, R. Sharp +32
We present self-consistent star formation rates derived through pan-spectral analysis of galaxies drawn from the Galaxy and Mass Assembly (GAMA) survey. We determine the most appro…
Galaxy and Mass Assembly (GAMA): survey diagnostics and core data release
S. P. Driver, D. T. Hill, L. S. Kelvin +52
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 acqui…
Sky subtraction at the Poisson limit with fibre-optic multi-object spectroscopy
Robert Sharp, Hannah Parkinson
We report on the limitations of sky subtraction accuracy for long duration fibre-optic multi-object spectroscopy of faint astronomical sources during long duration exposures. We sh…
Herschel-ATLAS: Dust temperature and redshift distribution of SPIRE and PACS detected sources using submillimetre colours
A. Amblard, A. Cooray, P. Serra +69
We present colour-colour diagrams of detected sources in the Herschel-ATLAS Science Demonstration Field from 100 to 500 microns using both PACS and SPIRE. We fit isothermal modifie…
