    • From Images to Features: Unbiased Morphology Classification via Variational Auto-Encoders and Domain Adaptation 

      Xu, Quanfeng; Shen, Shiyin; Souza, Rafael S. de; Chen, Mi; Ye, Renhao; She, Yumei; Chen, Zhu; Ishida, Emille E. O.; Krone-Martins, Alberto; Durgesh, Rupesh (2023-10-17)
      We present a novel approach for the dimensionality reduction of galaxy images by leveraging a combination of variational auto-encoders (VAE) and domain adaptation (DA). We demonstrate the effectiveness of this approach ...

    • Galmoss: A package for GPU-accelerated galaxy profile fitting 

      Chen, Mi; Souza, Rafael S. de; Xu, Quanfeng; Shen, Shiyin; Chies-Santos, Ana L.; Ye, Renhao; Canossa-Gosteinski, Marco A.; Cong, Yanping (2024-04-22)
      We introduce galmoss, a python-based, torch-powered tool for two-dimensional fitting of galaxy profiles. By seamlessly enabling GPU parallelization, galmoss meets the high computational demands of large-scale galaxy surveys, ...
