Imaging the 21-cm Signal from the Cosmic Dawn & Epoch of Reionization and the Connection with the Global Signal
Satadru Bag, Michele Bianco, Samir Choudhuri +12
The original baseline design for SKA-Low was motivated by the ability to produce tomographic images of the redshifted 21-cm signal, thus allowing the research field to move beyond…
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…
A candidate field for deep imaging of the Epoch of Reionization observed with MWA
Xueying Zhang, Qian Zheng, Linhui Wu +8
Deep imaging of structures from the Cosmic Dawn (CD) and the Epoch of Reionization (EoR) in five targeted fields is one of the highest priority scientific objectives for the Square…
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…
The Intensity of Diffuse Galactic Emission Reflected by Meteor Trails
Feiyu Zhao, Ruxi Liang, Zepei Yang +4
We calculate the reflection of diffuse galactic emission by meteor trails and investigate its potential relationship to Meteor Radio Afterglow (MRA). The formula to calculate the r…
