Galaxy And Mass Assembly: Automatic Morphological Classification of Galaxies Using Statistical Learning
Sreevarsha Sreejith, Sergiy Pereverzyev, Lee S. Kelvin +15
We apply four statistical learning methods to a sample of galaxies () from the Galaxy and Mass Assembly (GAMA) survey to test the feasibility of using automated algo…
Multiple Mechanisms Quench Passive Spiral Galaxies
Amelia Fraser-McKelvie, Michael J. I. Brown, Kevin Pimbblet +2
We examine the properties of a sample of 35 nearby passive spiral galaxies in order to determine their dominant quenching mechanism(s). All five low mass ($\textrm{M}_{\star} < 1 \…
GAMA/G10-COSMOS/3D-HST: The 0<z<5 cosmic star-formation history, stellar- and dust-mass densities
Simon P. Driver, Stephen K. Andrews, Elisabete da Cunha +30
We use the energy-balance code MAGPHYS to determine stellar and dust masses, and dust corrected star-formation rates for over 200,000 GAMA galaxies, 170,000 G10-COSMOS galaxies and…
The Evolutionary Sequence of Post-Starburst Galaxies
C. L. Wilkinson, K. A. Pimbblet, J. P. Stott
There are multiple ways in which to select post-starburst galaxies in the literature. In this work, we present a study into how two well-used selection techniques have consequences…
Triggering Active Galactic Nuclei in galaxy clusters
Madeline A. Marshall, Stanislav S. Shabala, Martin G. H. Krause +3
We model the triggering of Active Galactic Nuclei (AGN) in galaxy clusters using the semi- analytic galaxy formation model SAGE (?). We prescribe triggering methods based on the ra…
Galaxy And Mass Assembly (GAMA): The mechanisms for quiescent galaxy formation at
K. Rowlands, V. Wild, N. Bourne +14
One key problem in astrophysics is understanding how and why galaxies switch off their star formation, building the quiescent population that we observe in the local Universe. From…
