A Catalog of 13CO Clumps from the MWISP in l = 10°–20°
Chen, Zhiwei; Jiang, Zhibo; Zeng, Xiangyun +8 more
In this study, we present a catalog of molecular clumps extracted from 13CO (J = 1 ‑ 0) emission data of the Milky Way Imaging Scroll Painting (MWISP) project. The data covers the inner Milky Way within the longitude range 10° ≤ l ≤ 20° and the latitude strip of ∣b∣ ≤ 5.°25. The workflow for the extraction of clumps, namely Facet-SS-3D-…
Preparation for CSST: Star-galaxy Classification using a Rotationally Invariant Supervised Machine Learning Method
Fang, Guanwen; Lin, Zesen; Kong, Xu +6 more
Most existing star-galaxy classifiers depend on the reduced information from catalogs, necessitating careful data processing and feature extraction. In this study, we employ a supervised machine learning method (GoogLeNet) to automatically classify stars and galaxies in the COSMOS field. Unlike traditional machine learning methods, we introduce se…
Digitization of Astronomical Photographic Plates of China and Astrometric Measurement of Single-exposure Plates
Yang, Jing; Yu, Yong; Tang, Zheng-Hong +9 more
From the mid-19th century to the end of the 20th century, photographic plates served as the primary detectors for astronomical observations. Astronomical photographic observations in China began in 1901, and over a century, a total of approximately 30,000 astronomical photographic plates were captured. These historical plates play an irreplaceable…
