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…

Searching for the Role of Mergers in Fast and Early SMBH Growth: Morphological Decomposition of Quasars and Their Hosts at

Marcus O. Thomas, Ohad Shemmer, Benny Trakhtenbrot +4

We present rest-frame ultraviolet (UV) images of six luminous quasars at obtained with the Hubble Space Telescope (HST). These quasars exhibit a wide range of star for…

A Candidate Dual QSO at Cosmic Noon

Eilat Glikman, Rachel Langgin, Makoto A. Johnstone +6

We report the discovery of a candidate dual QSO at z=1.889, a redshift that is in the era known as "cosmic noon" where most of the Universe's black hole and stellar mass growth occ…

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…

Noise reduction on single-shot images using an autoencoder

Oliver. J. Bartlett, David. M. Benoit, Kevin. A. Pimbblet +2

We present an application of autoencoders to the problem of noise reduction in single-shot astronomical images and explore its suitability for upcoming large-scale surveys. Autoenc…

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…
