An adaptive parameter optimization method for astronomical image alignment using Bayesian optimization. I. A hierarchical search strategy for FWHM and SNR
Yongjie Zhang, Yigong Zhang, Zhenjun Zhang +6
The alignment and stacking of astronomical images are fundamental steps for detecting faint objects and performing high?precision astrometry. In traditional alignment workflows, th…
Predicting Astrometric Microlensing Events from Gaia DR3
Jie Su, Jiancheng Wang, Yigong Zhang +2
Currently astrometric microlensing is the only tool that can directly measure the mass of a single star, it can also help us to detect compact objects like isolated neutron stars a…
Astrometric observations of a near-Earth object using the image fusion technique
Yigong Zhang, Jiancheng Wang, Jie Su +2
The precise astrometric observation of small near-Earth objects (NEOs) is an important observational research topic in the astrometric discipline, which greatly promotes multidisci…
A fast point-pattern matching algorithm based on statistical method
Zhen-Jun Zhang, Yi-Gong Zhang, Xiang-Ming Cheng +2
We propose a new pattern-matching algorithm for matching CCD images to a stellar catalogue based statistical method in this paper. The method of constructing star pairs can greatly…
CCD astrometric observations of 2017 VR12,Camillo and Midas
Zhenjun Zhang, Yigong Zhang, Xiangming Cheng +2
We have observed three near-Earth objects(NEOs), 2017VR12, Camillo, and Midas during the year 2018. The observations were made by the 1-m telescope of Yunnan Observatory over 2 nig…
