Synthesis imaging with a lunar orbit array: I. global sky map and its systematics
Furen Deng, Yidong Xu, Fengquan Wu +3
Ground-based radio astronomical observation at frequencies below 30 MHz is hampered by the Ionosphere and radio frequency interference (RFI). The Discovering Sky at the Longest wav…
Beamforming in Interferometer Arrays with Cross-couplings
Yingfeng Liu, Shijie Sun, Kaifeng Yu +6
For an interferometric array, an image of the sky can be synthesized from interferometric visibilities, which are the cross-correlations of the received electric voltages of pairs…
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…
RFSoC receiver calibration system for 21-cm global spectrum experiments from space: The CosmoCube case
Jiacong Zhu, Eloy de Lera Acedo, Kaan Artuc +1
The CosmoCube project plans to deploy a global 21-cm spectrometer with 10-100 MHz observation band in a lunar orbit. The farside part of such an orbit, i.e. the part of orbit behin…
Measurement of the Primary Beam of the Tianlai Cylindrical Antenna Using an Unmanned Aerial Vehicle
Jixia Li, Nanben Suo, Shenzhe Xu +9
The Tianlai Cylinder Pathfinder Array consists of three adjacent cylindrical reflectors fixed on the ground, each 40 meters long and 15 meters wide, with the cylinder axis oriented…
Reconstructing the Anisotropic Ultra-long Wavelength Spectra using a Single Antenna on Lunar-orbit
Qige Ao, Furen Deng, Yidong Xu +3
The ultra-long wavelength sky ( MHz) is still largely unexplored, as the electromagnetic wave is heavily absorbed and distorted by the ionosphere on Earth. The far-si…
