Cross-survey Image Transformation: Enhancing SDSS and DECaLS Images to Near-HSC Quality for Advanced Astronomical Analysis

The Astrophysical Journal Supplement Series
This study focuses on transforming galaxy images between astronomical surveys, specifically enhancing images from the Sloan Digital Sky Survey (SDSS) and the Dark Energy Camera Legacy Survey (DECaLS) to achieve quality comparable to the Hyper Suprime-Cam

Detecting Galactic Rings in the DESI Legacy Imaging Surveys with Semisupervised Deep Learning

The Astrophysical Journal Supplement Series
The ring structures of disk galaxies are vital for understanding galaxy evolution and dynamics. However, due to the scarcity of ringed galaxies and challenges in their identification, traditional methods often struggle to efficiently obtain statistically

Identifying Dust-lane Spheroidal Galaxies in DESI Legacy Imaging Surveys Using Semisupervised Methods

The Astrophysical Journal Supplement Series
Dust-lane spheroidal galaxies (DLSGs) are unique astrophysical systems that exhibit the morphology of early-type galaxies (ETGs) but are distinguished by prominent dust lanes.
