The Electrical Design of a Membrane Antenna for Lunar-based Low-frequency Radio Telescope
Suonanben, Fengquan Wu, Kai He +15
Detecting primordial fluctuations from the cosmic dark ages requires extremely large low-frequency radio telescope arrays deployed on the far side of the Moon. The antenna of such…
The FAST HI 21-cm absorption blind survey. II. -- Statistic Exploration for Associated and Intervening systems
Wenkai Hu, Yougang Wang, Yichao Li +12
We present an extragalactic HI 21-cm absorption lines catalog from a blind search at z 0.35, using drift-scan data collected in 1325.6 hours by the ongoing Commensal Ra…
The FRB-searching pipeline of the Tianlai Cylinder Pathfinder Array
Zijie Yu, Furen Deng, Shijie Sun +14
This paper presents the design, calibration, and survey strategy of the Fast Radio Burst (FRB) digital backend and its real-time data processing pipeline employed in the Tianlai Cy…
Forecast measurement of the 21 cm global spectrum from Lunar orbit with the Vari-Zeroth-Order Polynomial (VZOP) method
Tianyang Liu, Jiajun Zhang, Yuan Shi +7
The cosmic 21 cm signal serves as a crucial probe for studying the evolutionary history of the Universe. However, detecting the 21 cm signal poses significant challenges due to its…
Calibration Error in 21-centimeter Global Spectrum Experiments
Shijie Sun, Eloy de Lera Acedo, Fengquan Wu +3
The redshifted 21 cm line signal is a powerful probe of the cosmic dawn and the epoch of reionization. The global spectrum can potentially be detected with a single antenna and spe…
Tackling Challenges in 21cm Global Spectrum Experiment: the Impact of Ionosphere and Beam Distortion
Yue Wang, Xin Wang, Shijie Sun +3
The HI 21cm global signal from the Cosmic Dawn and the Epoch of Reionization (EoR) offers critical insights into the evolution of our Universe. Yet, its detection presents signific…
Large-scale Array for Radio Astronomy on the Farside
Xuelei Chen, Feng Gao, Fengquan Wu +20
At the Royal Society meeting in 2023, we have mainly presented our lunar orbit array concept called DSL, and also briefly introduced a concept of a lunar surface array, LARAF. As t…
