A pilot study on the CSST astrometric capability: Detecting astrometric binaries with Gaia synergy via simulated data
Shangyu Wen, Shilong Liao, Zhaoxiang Qi +8
Context. The China Space-station Survey Telescope (CSST) will provide deep, wide-field epoch astrometry during its 10-year mission. Astrometric binary orbits constrain the masses o…
Shigatse Astronomical Site Testing. I. Cloud-cover Climatology and Selected Local Meteorological Conditions
Baiyu Zhang, Hejun Yang, Xiaojun Dong +15
As the first paper in a Shigatse astronomical site-testing series, we present a multi-source assessment of cloud cover and selected local meteorological conditions at the Shigatse…
Astrometric Calibration of the BeijingArizona Sky Survey
Xiyan Peng, Zhaoxiang Qi, Tianmeng Zhang +13
We present the astrometric calibration of the Beijing-Arizona Sky Survey (BASS). The BASS astrometry was tied to the International Celestial Reference Frame via the \emph{Gaia} Dat…
Simulation of CSSTs astrometric capability
Zhensen Fu, Zhaoxiang Qi, Shilong Liao +5
The China Space Station Telescope (CSST) will enter a low Earth orbit around 2024 and operate for 10 years, with seven of those years devoted to surveying the area of the median-to…
The Robotic Multi-Object Focal Plane System of the Dark Energy Spectroscopic Instrument (DESI)
Joseph Harry Silber, Parker Fagrelius, Kevin Fanning +97
A system of 5,020 robotic fiber positioners was installed in 2019 on the Mayall Telescope, at Kitt Peak National Observatory. The robots automatically re-target their optical fiber…
Photometric calibration for the Beijing-Arizona Sky Survey and Mayall z-band Legacy Survey
Zhimin Zhou, Xu Zhou, Hu Zou +14
We present the photometric calibration of the Beijing-Arizona Sky Survey (BASS) and Mayall z-band Legacy Survey (MzLS), which are two of the three wide-field optical legacy imaging…
Overview of the DESI Legacy Imaging Surveys
Arjun Dey, David J. Schlegel, Dustin Lang +157
The DESI Legacy Imaging Surveys are a combination of three public projects (the Dark Energy Camera Legacy Survey, the Beijing-Arizona Sky Survey, and the Mayall z-band Legacy Surve…
The Second Data Release of the Beijing-Arizona Sky Survey
Hu Zou, Tianmeng Zhang, Zhimin Zhou +28
This paper presents the second data release (DR2) of the Beijing-Arizona Sky Survey (BASS). BASS is an imaging survey of about 5400 deg in and bands using the 2.3 m Bok…
The DESI Experiment Part II: Instrument Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectropic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations and the growth of structure through redshift…
The DESI Experiment Part I: Science,Targeting, and Survey Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through…
An Investigation of the Absolute Proper Motions of the SCUSS Catalog
Xiyan Peng, Zhaoxiang Qi, Zhenyu Wu +21
Absolute proper motions for 7.7 million objects were derived based on data from the South Galactic Cap u-band Sky Survey (SCUSS) and astrometric data derived from uncompress…
