Impact of Satellite Constellations on Observations with the 80-cm Telescope and the Mini-SiTian at the Xinglong Observatory, NAOC
Jing Ren, Zhou Fan, Hong-rui Gu +6
The rapid development of mega-constellations in low Earth orbit (LEO) severely impacts ground-based optical astronomical observations. By combining WorldWide Telescope (WWT) simula…
Slitless Spectroscopy Source Detection Using YOLO Deep Neural Network
Xiaohan Chen, Man I Lam, Yingying Zhou +6
Slitless spectroscopy eliminates the need for slits, allowing light to pass directly through a prism or grism to generate a spectral dispersion image that encompasses all celestial…
Artificial Satellite Trails Detection Using U-Net Deep Neural Network and Line Segment Detector Algorithm
Xiaohan Chen, Hongrui Gu, Cunshi Wang +6
With the rapid increase in the number of artificial satellites, astronomical imaging is experiencing growing interference. When these satellites reflect sunlight, they produce stre…
The Mini-SiTian Array: first-two-year operation
Min He, Hong Wu, Liang Ge +70
The SiTian project, designed to utilize 60 telescopes distributed across multiple sites in China, is a next-generation time-domain survey initiative. As a pathfinder for the SiTian…
