AstroVaDEr: Astronomical Variational Deep Embedder for Unsupervised Morphological Classification of Galaxies and Synthetic Image Generation
Spindler, Ashley; Geach, James E.; Smith, Michael J. (2021-03-01)We present AstroVaDEr (Astronomical Variational Deep Embedder), a variational autoencoder designed to perform unsupervised clustering and synthetic image generation using astronomical imaging catalogues. The model is a ... -
Deep Learning Segmentation of Spiral Arms and Bars
Walmsley, Mike; Spindler, Ashley (2023-12)We present the first deep learning model for segmenting galactic spiral arms and bars. In a blinded assessment by expert astronomers, our predicted spiral arm masks are preferred over both current automated methods (99% ...
