and band sky brightness measurements from polar day to polar night at Dome A, Antarctica
Jinji Li, Bin Ma, Haonan Yang +9
The near-infrared (NIR) sky brightness is a fundamental parameter for evaluating the performance of ground-based infrared observatories. Dome~A on the Antarctic plateau offers exce…
Deep-learning-based prediction of Precipitable Water Vapor in the Chajnantor area
Alison Matus-Bello, Silvia E. Restrepo, Ricardo Bustos +7
Astronomical observations at millimeter and submillimeter wavelengths heavily depend on the amount of Precipitable Water Vapor (PWV) in the atmosphere, directly affecting the sky t…
Antarctic Infrared Binocular Telescope. I. System Overview, Laboratory Testing, and On-Sky Performance Evaluation
Zhongnan Dong, Bin Ma, Haoran Zhang +5
Infrared time-domain surveys remain significantly underdeveloped compared with their optical counterparts. We have developed the Antarctic Infrared Binocular Telescope (AIRBT) to s…
Probing the cosmological 21~cm global signal from the Antarctic ice sheet
Shijie Sun, Jiaqin Xu, Minquan Zhou +7
The redshifted 21 cm line, arising from neutral hydrogen, offers a unique probe into the intergalactic medium and the first stars and galaxies formed in the early universe. However…
