Cluster passage driving galaxy kinematic and structural evolution in the SAMI Galaxy Survey
Ryan Bagge, Caroline Foster, Sarah Brough +6
The cluster environment can have a significant impact on galaxy evolution. We study the impact that passage through a cluster has on stellar and ionised gas kinematics for galaxies…

The SAMI Galaxy Survey: large-scale environment affects galaxy spin amplitudes and the formation of slow rotators
Stefania Barsanti, Scott M. Croom, Matthew Colless +9
We explore the impact of the large-scale 3D density field, as defined by deep, wide-field galaxy surveys, on stellar spin () and the distributions of fast and slow ro…
