Galaxy-SMBH co-evolution in 2,435 DESI disk galaxies and merger-free BH growth in bulgeless disks
Sophie M. Jewell, Rebecca J. Smethurst, Chris J. Lintott +8
We analyse black hole scaling relations for disk-dominated galaxies, and present evidence for secularly driven galaxy-black hole co-evolution. We do this observationally by looking…
Deep Learning Segmentation of Spiral Arms and Bars for 600,000 Galaxies in DESI
Ashley Spindler, Mike Walmsley, Karen L. Masters +4
We present a catalogue of segmentation maps identifying the extent of spiral arms and bars of 639,636 galaxies in the DESI Legacy Survey. To produce these maps, we have trained a d…
The effects of image augmentations when training machine learning models in astronomy
Leon H. Butterworth, Ashley Spindler
We measure the influence of image augmentations and training dataset size when training a deep neural network to classify galaxy morphology. Data augmentation is an integral step w…
