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…
Separating the EoR Signal with a Convolutional Denoising Autoencoder: A Deep-learning-based Method
Weitian Li, Haiguang Xu, Zhixian Ma +7
When applying the foreground removal methods to uncover the faint cosmological signal from the epoch of reionization (EoR), the foreground spectra are assumed to be smooth. However…
The Giant Radio Array for Neutrino Detection (GRAND): Present and Perspectives
Ke Fang, Jaime Álvarez-Muñiz, Rafael Alves Batista +33
The Giant Radio Array for Neutrino Detection (GRAND) aims at detecting ultra-high energy extraterrestrial neutrinos via the extensive air showers induced by the decay of tau lepton…
The Giant Radio Array for Neutrino Detection
Olivier Martineau-Huynh, Mauricio Bustamante, Washington Carvalho +19
The Giant Radio Array for Neutrino Detection (GRAND) is a planned array of ~200 000 radio antennas deployed over ~200 000 km2 in a mountainous site. It aims primarly at detecting h…
The radio environment of the 21 Centimeter Array: RFI detection and mitigation
Yan Huang, Xiang-Ping Wu, Qian Zheng +2
Detection and mitigation of radio frequency interference (RFI) is the first and also the key step for data processing in radio observations, especially for ongoing low frequency ra…
