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…
Variable Stars Observed in the Galactic Disk by AST3-1 from Dome A, Antarctica
Lingzhi Wang, Bin Ma, Gang Li +15
AST3-1 is the second-generation wide-field optical photometric telescope dedicated to time domain astronomy at Dome A, Antarctica. Here we present the results of band images su…
Meteorological data for the astronomical site at Dome A, Antarctica
Yi Hu, Zhaohui Shang, Michael C. B. Ashley +7
We present an analysis of the meteorological data collected at Dome A, Antarctica by the Kunlun Automated Weather Station, including temperatures and wind speeds at eight elevation…
Problems with twilight/supersky flat-field for wide-field robotic telescopes and the solution
Peng Wei, Zhaohui Shang, Bin Ma +3
Twilight/night sky images are often used for flat-fielding CCD images, but the brightness gradient in twilight/night sky causes problems of accurate flat-field correction in astron…
The nonlinear photon transfer curve of CCDs and its effects on photometry
Bin Ma, Zhaohui Shang, Lifan Wang +3
The photon transfer curve (PTC, variance vs. signal level) is a commonly used and effective tool in characterizing CCD performance. It is theoretically linear in the range where ph…
