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: Morphologies based on UKIDSS NIR Imaging for 71,052 Galaxies
Karen L. Masters, Melanie Galloway, Lucy Fortson +6
We present morphological classifications based on Galaxy Zoo analysis of 71,052 galaxies with imaging from the United Kingdom Infrared Telescope Infrared Deep Sky Survey (UKIDSS).…
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 effects of bar strength and kinematics on galaxy evolution: slow strong bars affect their hosts the most
Tobias Géron, R. J. Smethurst, Chris Lintott +5
We study how bar strength and bar kinematics affect star formation in different regions of the bar by creating radial profiles of EW[H] and D4000 using data from SDSS…
