The most luminous, merger-free AGN show only marginal correlation with bar presence

Izzy L. Garland, Matthew J. Fahey, Brooke D. Simmons +13

The role of large-scale bars in the fuelling of active galactic nuclei (AGN) is still debated, even as evidence mounts that black hole growth in the absence of galaxy mergers cumul…

Harnessing the Hubble Space Telescope Archives: A Catalogue of 21,926 Interacting Galaxies

David O'Ryan, Bruno Merín, Brooke D. Simmons +13

Mergers play a complex role in galaxy formation and evolution. Continuing to improve our understanding of these systems require ever larger samples, which can be difficult (even im…

Quantifying the Poor Purity and Completeness of Morphological Samples Selected by Galaxy Colour

Rebecca J. Smethurst, Karen L. Masters, Brooke D. Simmons +7

The galaxy population is strongly bimodal in both colour and morphology, and the two measures correlate strongly, with most blue galaxies being late-types (spirals) and most early-…
