Timescales for the Effects of Interactions on Galaxy Properties and SMBH Growth
D. O'Ryan, B. D. Simmons, A. L. Faisst +15
Galaxy interaction and merging have clear effects on the systems involved. We find an increase in the star formation rate (SFR), potential ignition of active galactic nuclei (AGN)…
Galaxy Zoo JWST: Up to 75% of discs are featureless at
R. J. Smethurst, B. D. Simmons, T. Géron +21
We have not yet observed the epoch at which disc galaxies emerge in the Universe. While high- measurements of large-scale features such as bars and spiral arms trace the evoluti…
Structural Decomposition of Merger-Free Galaxies Hosting Luminous AGNs
Matthew J. Fahey, Izzy. L. Garland, Brooke. D. Simmons +10
Active galactic nucleus (AGN) growth in disk-dominated, merger-free galaxies is poorly understood, largely due to the difficulty in disentangling the AGN emission from that of the…
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…
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…
