Galaxies fall broadly into two categories: star-forming (blue) galaxies and quiescent (red) galaxies. In between, one finds the less populated 'green valley'. Some of these galaxies are suspected to be in the process of ceasing their star formation t...

Journal Article
Holwerda, B. W., Smith, D., Porter, L., Henry, C., Porter-Temple, R., Cook, K., Pimbblet, K. A., Hopkins, A. M., Bilicki, M., Turner, S., Acquaviva, V., Wang, L., Wright, A. H., Kelvin, L.

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.

Galaxy and Mass Assembly (GAMA): The Weak Environmental Dependence of Quasar Activity at 0.1< z <0.35 (2022)
Journal Article
Wethers, C. F., Acharya, N., De Propris, R., Kotilainen, J., Baldry, I. K., Brough, S., Driver, S. P., Graham, A. W., Holwerda, B. W., Hopkins, A. M., López-Sánchez, A. R., Loveday, J., Phillipps, S., Pimbblet, K. A., Taylor, E., Wang, L., & Wright, A. H. (2022). Galaxy and Mass Assembly (GAMA): The Weak Environmental Dependence of Quasar Activity at 0.1< z

Understanding the connection between nuclear activity and galaxy environment remains critical in constraining models of galaxy evolution. By exploiting extensive catalogued data from the Galaxy and Mass Assembly (GAMA) survey, we identify a represent...

In Galaxy And Mass Assembly Data Release 4 (GAMA DR4), we make available our full spectroscopic redshift sample. This includes 248 682 galaxy spectra, and, in combination with earlier surveys, results in 330 542 redshifts across five sky regions cove...
