Galaxy Zoo DESI: large-scale bars as a secular mechanism for triggering AGN

Izzy L. Garland, Mike Walmsley, Maddie S. Silcock +13

Despite the evidence that supermassive black holes (SMBHs) co-evolve with their host galaxy, and that most of the growth of these SMBHs occurs via merger-free processes, the underl…

Galaxy Zoo DESI: Detailed Morphology Measurements for 8.7M Galaxies in the DESI Legacy Imaging Surveys

Mike Walmsley, Tobias Géron, Sandor Kruk +13

We present detailed morphology measurements for 8.67 million galaxies in the DESI Legacy Imaging Surveys (DECaLS, MzLS, and BASS, plus DES). These are automated measurements made b…

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-…
