Galaxy and Mass Assembly (GAMA): Witnessing the assembly of the cluster Abell 1882
M. S. Owers, I. K. Baldry, A. E. Bauer +14
We present a combined optical and X-ray analysis of the rich cluster Abell 1882 with the aim of identifying merging substructure and understanding the recent assembly history of th…
Galaxy And Mass Assembly (GAMA): Linking Star Formation Histories and Stellar Mass Growth
Amanda E. Bauer, A. M. Hopkins, M. Gunawardhana +23
We present evidence for stochastic star formation histories in low-mass (M* < 10^10 Msun) galaxies from observations within the Galaxy And Mass Assembly (GAMA) survey. For ~73,000…
Galaxy And Mass Assembly (GAMA): A deeper view of the mass, metallicity, and SFR relationships
M. A. Lara-Lopez, A. M. Hopkins, A. R. Lopez-Sanchez +18
A full appreciation of the role played by gas metallicity (Z), star-formation rate (SFR), and stellar mass is fundamental to understanding how galaxies form and evolve. The connect…
Galaxy And Mass Assembly: Evolution of the Halpha luminosity function and star formation rate density up to z<0.35
M. L. P. Gunawardhana, A. M. Hopkins, J. Bland-Hawthorn +28
Measurements of the low-z Halpha luminosity function have a large dispersion in the local number density of sources, and correspondingly in the SFR density. The possible causes for…
Galaxy And Mass Assembly (GAMA): The connection between metals, specific-SFR, and HI gas in galaxies: the Z-SSFR relation
M. A. Lara-López, A. M. Hopkins, A. R. López-Sánchez +10
We study the interplay between gas phase metallicity (Z), specific star formation rate (SSFR) and neutral hydrogen gas (HI) for galaxies of different stellar masses. Our study uses…
GAMA/H-ATLAS: Linking the Properties of Sub-mm Detected and Undetected Early-Type Galaxies: I. z0.06 Sample
N. K. Agius, A. E. Sansom, C. C. Popescu +34
We present two large, nearby (0.013z0.06) samples of Early-Type Galaxies (ETGs): a visually classified sample of 220 ETGs, created using source-matched data from the Gala…
