The Next-Generation 21CMA Telescope: Design, Commissioning, and Instrumental Effects in an SKA-LFAA-Like System
Jun-Hua Gu, Quan Guo, Liang Dong +11
As the Square Kilometre Array (SKA) approaches operational status, its complex digital architecture introduces new instrumental challenges. To explore relevant observational and da…
Simulation and Data Processing of Beamforming Experiments with Four 21CMA Stations
Feiyu Zhao, Quan Guo, Junhua Gu +3
We present an end-to-end simulation and data-processing framework for digital beamforming experiments conducted with four stations of the 21 Centimeter Array (21CMA). Motivated by…
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…
Performance of the Segment Anything Model in Various RFI/Events Detection in Radio Astronomy
Yanbin Yang, Feiyu Zhao, Ruxi Liang +4
The emerging era of big data in radio astronomy demands more efficient and higher-quality processing of observational data. While deep learning methods have been applied to tasks s…
Influence of sources with a spectral peak in the detection of Cosmic Dawn and Epoch of Reionization
Mengfan He, Qian Zheng, Quan Guo +5
Foreground removal is one of the biggest challenges in the detection of the Cosmic Dawn (CD) and Epoch of Reionization (EoR). Various foreground subtraction techniques have been de…
