An HI study of a large sample of ultra-diffuse galaxies
Ruilei Zhou, Ming Zhu, Chuan-Peng Zhang +5
By cross-matching the SMUDGes catalog with the FASHI and ALFALFA HI surveys, we construct an HI-detected sample of 112 ultra-diffuse galaxies (UDGs) and 48 low-surface-brightness (…
The Mini-SiTian Array: Evaluation Camera System
Yu Zhang, Lin Du, Yi Hu +7
The Mini-SiTian project, which is the pathfinder for the SiTian project, utilizes three 30 cm telescopes equipped with commercial CMOS cameras (ZWO ASI6200MM Pro) to simulate large…
StarWhisper Telescope: An AI framework for automating end-to-end astronomical observations
Cunshi Wang, Yu Zhang, Yuyang Li +25
The exponential growth of large-scale telescope arrays has boosted time-domain astronomy development but introduced operational bottlenecks, including labor-intensive observation p…
Almost Optically Dark Galaxies in DECaLS (I): Detection, Optical Properties and Possible Origins
Lin Du, Wei Du, Cheng Cheng +3
We report the discovery of eight optical counterparts of ALFALFA extragalactic objects from DECaLS, five of which are discovered for the first time. These objects were flagged as H…
Star-forming Main Sequence of Giant Low Surface Brightness Galaxies
Wei Du, Cheng Cheng, Pengliang Du +2
Giant Low Surface Brightness Galaxies (GLSBGs) are fundamentally distinct from normal galaxies (LSBGs) in star formation and evolution. In this work, we collected 27 local GLSBGs.…
