From Simulations to Surveys: Domain Adaptation for Galaxy Observations

arXiv — cs.LGTuesday, November 25, 2025 at 5:00:00 AM
  • A new domain adaptation pipeline has been developed to enhance the accuracy of galaxy observations by training on simulated TNG50 galaxies and evaluating on real SDSS galaxies. This approach addresses the challenges posed by domain shifts in various factors such as PSF and noise, which can hinder the reliable inference of physical properties like morphology and stellar mass.
  • The significance of this development lies in its potential to provide astronomers with automated tools for analyzing vast photometric surveys, ultimately improving the understanding of galaxy formation and evolution through more accurate data interpretation.
  • This advancement reflects a broader trend in artificial intelligence where machine learning techniques are increasingly applied to complex scientific problems, such as pose estimation in microrobots and lesion segmentation in medical imaging, showcasing the versatility and impact of AI across diverse fields.
