Galaxy And Mass Assembly (GAMA): Self-Organizing Map Application on Nearby Galaxies
B. W. Holwerda, Dominic Smith, Lori Porter +12
Galaxy populations show bimodality in a variety of properties: stellar mass, colour, specific star-formation rate, size, and Sérsic index. These parameters are our feature space.…
Synergies between low- and intermediate-redshift galaxy populations revealed with unsupervised machine learning
Sebastian Turner, MaÅgorzata Siudek, Samir Salim +10
The colour bimodality of galaxies provides an empirical basis for theories of galaxy evolution. However, the balance of processes that begets this bimodality has not yet been const…
Compact galaxies and the size-mass galaxy distribution from a colour-selected sample at 0.04 < z < 0.15 supplemented by ugrizYJHK photometric redshifts
Ivan K. Baldry, Tricia Sullivan, Raffaele Rani +1
The size-mass galaxy distribution is a key diagnostic for galaxy evolution. Massive compact galaxies are potential surviving relics of a high-redshift phase of star formation. Some…
Reproducible -means clustering in galaxy feature data from the GAMA survey
Sebastian Turner, Lee S. Kelvin, Ivan K. Baldry +6
A fundamental bimodality of galaxies in the local Universe is apparent in many of the features used to describe them. Multiple sub-populations exist within this framework, each rep…
