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…
External Calibrator in Global Signal Experiment for Detection of the Epoch of Reionization
Yan Huang, Xiang-Ping Wu, Quan Guo +5
We present a conceptual design study of external calibrators in the 21 cm experiment towards detecting the globally averaged radiation of the epoch of reionization (EoR). Employmen…
The Impact of Tandem Redundant/Sky-Based Calibration in MWA Phase II Data Analysis
Zheng Zhang, Jonathan C. Pober, Wenyang Li +26
Precise instrumental calibration is of crucial importance to 21-cm cosmology experiments. The Murchison Widefield Array's (MWA) Phase II compact configuration offers us opportuniti…
Pre-selection of the Candidate Fields for Deep Imaging of the Epoch of Reionization with SKA1-Low
Qian Zheng, Xiang-Ping Wu, Quan Guo +4
The Square Kilometre Array (SKA) will be the first low-frequency instrument with the capability to directly image the structures of the Epoch of Reionization (EoR). Indeed, deep im…
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…
Limits of noise and confusion in the MWA GLEAM year 1 survey
T. M. O. Franzen, C. A. Jackson, J. R. Callingham +21
The GaLactic and Extragalactic All-sky MWA survey (GLEAM) is a new relatively low resolution, contiguous 72-231 MHz survey of the entire sky south of declination +25 deg. In this p…
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…
