Abstract
This study evaluates the performance of existing visual foundation models, based on ViT, SwinV2, BEiT or DINOv2, for astronomical applications, particularly galaxy morphological classification. We explore different fine-tuning strategies to specialize DINOv2 for astronomy and report results on the Galaxy10 DECaLS dataset.
