Deep Learning Segmentation of Spiral Arms and Bars.
In: Machine Learning and the Physical Sciences Workshop at NuerIPS 2023, 2023-12-15 - 2023-12-15, New Orleans Ernest N. Morial Convention Center.
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% of evaluations) and our original volunteer labels (79% of evaluations). Experts rated our spiral arm masks as `mostly good' to `perfect' in 89% of evaluations. Bar lengths trivially derived from our predicted bar masks are in excellent agreement with a dedicated crowdsourcing project. The pixelwise precision of our masks, previously impossible at scale, will underpin new research into how spiral arms and bars evolve.
