Journal Article
Holwerda, B. W., Smith, D., Porter, L., Henry, C., Porter-Temple, R., Cook, K., …Grootes, M. W. (2022). Galaxy and mass assembly (GAMA): Self-Organizing Map application on nearby galaxies. Monthly notices of the Royal Astronomical Society, 513(2), 1972-1984. https://doi.org/10.1093/mnras/stac889

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. We use an existing sample of 7556 galaxies from the Galaxy and Mass Ass... Read More about Galaxy and mass assembly (GAMA): Self-Organizing Map application on nearby galaxies.
