The Short-spacing Interferometer Array for Global 21-cm Signal Detection (SIGMA): Design of the Antennas and Layout
Feiyu Zhao, Quan Guo, Qian Zheng +8
Numerous experiments have been designed to investigate the Cosmic Dawn (CD) and Epoch of Reionization (EoR) by examining redshifted 21-cm emissions from neutral hydrogen. Detecting…
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…
Detecting Cosmic 21 cm Global Signal Using an Improved Polynomial Fitting Algorithm
Tianyang Liu, Junhua Gu, Quan Guo +3
Detecting the cosmic 21 cm signal from Epoch of Reionization (EoR) has always been a difficult task. Although the Galactic foreground can be regarded as a smooth power-law spectrum…
Global CD/EoR Signal Detection with a Dense Digital Beamforming Array and Beyond
Junhua Gu, Jingying Wang, Huanyuan Shan +5
The global neutral hydrogen 21 cm signal extracted from the all-sky averaged radio spectra is one of the signatures of the Cosmic Dawn and Epoch of Reionization (CD/EoR). The frequ…
