A Large and Precise All-Sky Photometric Standard Star Dataset Across More Than 200 Passbands
Kai Xiao, Yang Huang, Haibo Yuan +12
High-precision photometric standard stars play a key role in enabling accurate photometric calibration and advancing various fields of astronomy. However, due to limitations in cal…
A Highly Efficient Cross-matching Scheme using Learned Index Structure
Phu-Minh Lam, Dongwei Fan, Hongbo Wei +6
Spatial data fusion is a bottleneck when it meets the scale of 10 billion records. Cross-matching celestial catalogs is just one example of this. To challenge this, we present a fr…
Photometric redshift estimation of galaxies in the DESI Legacy Imaging Surveys
Changhua Li, Yanxia Zhang, Chenzhou Cui +14
The accurate estimation of photometric redshifts plays a crucial role in accomplishing science objectives of the large survey projects. The template-fitting and machine learning ar…
Photometric Redshift Estimation of BASS DR3 Quasars by Machine Learning
Changhua Li, Yanxia Zhang, Chenzhou Cui +9
Correlating BASS DR3 catalogue with ALLWISE database, the data from optical and infrared information are obtained. The quasars from SDSS are taken as training and test samples whil…
GWOPS: A VO-technology Driven Tool to Search for the Electromagnetic Counterpart of Gravitational Wave Event
Yunfei Xu, Dong Xu, Chenzhou Cui +11
The search and follow-up observation of electromagnetic (EM) counterparts of gravitational waves (GW) is a current hot topic of GW cosmology. Due to the limitation of the accuracy…
Optimal Probabilistic Catalogue Matching for Radio Sources
Dongwei Fan, Tamás Budavári, Ray P. Norris +1
Cross-matching catalogues from radio surveys to catalogues of sources at other wavelengths is extremely hard, because radio sources are often extended, often consist of several spa…
