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…
Resolution enhancement of SOHO/MDI Magnetograms
Ying Qin, Kai-Fan Ji, Hui Liu +1
Research on the solar magnetic field and its effects on solar dynamo mechanisms and space weather events has benefited from the continual improvements in instrument resolution and…
An Exposure Meter of Lijiang Fiber-fed High-Resolution Spectrograph
Xiao-Guang Yu, Kai-Fan Ji, Xi-Liang Zhang +4
In 2016, an exposure meter was installed on the Lijiang Fiber-fed High-Resolution Spectrograph to monitor the coupling of starlight to the science fiber during observations. Based…
Finding Quasars behind the Galactic Plane. II. Spectroscopic Identifications of 204 Quasars at
Yuming Fu, Xue-Bing Wu, Linhua Jiang +21
Quasars behind the Galactic plane (GPQs) are important astrometric references and valuable probes of Galactic gas, yet the search for GPQs is difficult due to severe extinction and…
Reverberation Mapping Measurements of Black Hole Masses and Broad-Line Region Kinematics in Mrk 817 and NGC 7469
Kai-Xing Lu, Jian-Guo Wang, Zhi-Xiang Zhang +7
We present the results from a spectroscopic monitoring campaign to obtain reverberation-mapping measurements and investigate the broad-line region kinematics for active galactic nu…
A correction method for the telluric absorptions and application to Lijiang Observatory
Kai-Xing Lu, Zhi-Xiang Zhang, Ying-Ke Huang +7
Observing a telluric standard star for correcting the telluric absorption lines of spectrum will take a significant amount of precious telescope time, especially in the long-term s…
