Digitization of Astronomical Photographic Plate of China and Astrometric Measurement of Single-exposure Plates
Zheng-Jun Shang, Yong Yu, Liang-Liang Wang +9
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…
Molecular Lines of 13 Galactic Infrared Bubble Regions
Qing-zeng Yan, Ye Xu, Bo Zhang +3
We investigated the physical properties of molecular clouds and star formation processes around infrared bubbles which are essentially expanding HII regions. We performed observati…
Sparse aperture differential piston measurements using the pyramid wave-front sensor
Carmelo Arcidiacono, Xinyang Chen, Zhaojun Yan +7
In this paper we report on the laboratory experiment we settled in the Shanghai Astronomical Observatory (SHAO) to investigate the pyramid wavefront sensor (WFS) ability to measure…
A geometric delay model for Space VLBI
Shi-Long Liao, Zheng-Hong Tang, Zhao-Xiang Qi
A relativistic delay model for space very long baseline interferometry (hereafter SVLBI) observation of sources at infinite distance is derived. In SVLBI, where one station is on a…
