Galaxy and Mass Assembly (GAMA): Selection of the Most Massive Clusters
Hector J. Ibarra-Medel, Maritza Lara-Lopez, Omar Lopez-Cruz
We have developed a galaxy cluster finding technique based on the Delaunay Tessellation Field Estimator (DTFE) combined with caustic analysis. Our method allows us to recover clust…
Galaxy and Mass Assembly (GAMA): Fine filaments of galaxies detected within voids
Mehmet Alpaslan, Aaron S. G. Robotham, Danail Obreschkow +15
Based on data from the Galaxy and Mass Assembly (GAMA) survey, we report on the discovery of structures that we refer to as `tendrils' of galaxies: coherent, thin chains of galaxie…
Galaxy And Mass Assembly (GAMA): The large scale structure of galaxies and comparison to mock universes
Mehmet Alpaslan, Aaron S. G. Robotham, Simon Driver +18
From a volume limited sample of 45,542 galaxies and 6,000 groups with we use an adapted minimal spanning tree algorithm to identify and classify large scale structur…
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: 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…
The metallicity - redshift relations for emission-line SDSS galaxies: examination of the dependence on the star formation rate
L. S. Pilyugin, M. A. Lara-Lopez, E. K. Grebel +5
We analyse the oxygen abundance and specific star formation rates (sSFR) variations with redshift in star-forming SDSS galaxies of different masses. We find that the maximum value…
