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…
CosmicWeb-21cm array: A New Radio Observation Array Design for 21cm Cosmology
Jiancheng Wang, Jirong Mao, Xiangming Cheng +10
This paper presents the CosmicWeb-21cm array, a novel radio interferometer designed to overcome the key challenges in 21 cm cosmology. Its core innovations include: (1) a multi-sca…
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…
A flexible method for estimating luminosity functions via Kernel Density Estimation -- II. Generalization and Python implementation
Zunli Yuan, Xibin Zhang, Jiancheng Wang +2
We propose a generalization of our previous KDE (kernel density estimation) method for estimating luminosity functions (LFs). This new upgrade further extend the application scope…
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…
