Detecting HI Galaxies with Deep Neural Networks in the Presence of Radio Frequency Interference
Ruxi Liang, Furen Deng, Zepei Yang +9
In neutral hydrogen (HI) galaxy survey, a significant challenge is to identify and extract the HI galaxy signal from observational data contaminated by radio frequency interference…
Eliminating polarization leakage effect for neutral hydrogen intensity mapping with deep learning
Li-Yang Gao, Yichao Li, Shulei Ni +1
The neutral hydrogen (HI) intensity mapping (IM) survey is regarded as a promising approach for cosmic large-scale structure (LSS) studies. A major issue for the HI IM survey is to…
1/f Noise Analysis for FAST HI Intensity Mapping Drift-Scan Experiment
Wenkai Hu, Yichao Li, Yougang Wang +8
We investigate the 1/f noise of the Five-hundred-meter Aperture Spherical Telescope (FAST) receiver system using drift-scan data from an intensity mapping pilot survey. All the 19…
Data Processing Pipeline For Tianlai Experiment
Shifan Zuo, Jixia Li, Yichao Li +7
The Tianlai project is a 21cm intensity mapping experiment aimed at detecting dark energy by measuring the baryon acoustic oscillation (BAO) features in the large scale structure p…
The Tianlai Dish Pathfinder Array: design, operation and performance of a prototype transit radio interferometer
Fengquan Wu, Jixia Li, Shifan Zuo +34
The Tianlai Dish Pathfinder Array is a radio interferometer designed to test techniques for 21~cm intensity mapping in the post-reionization universe as a means for measuring large…
The Tianlai Cylinder Pathfinder Array: System Functions and Basic Performance Analysis
Jixia Li, Shifan Zuo, Fengquan Wu +35
The Tianlai Cylinder Pathfinder is a radio interferometer array designed to test techniques for 21 cm intensity mapping in the post-reionization Universe, with the ultimate aim of…
Progress in the Construction and Testing of the Tianlai Radio Interferometers
Santanu Das, Christopher J. Anderson, Reza Ansari +44
The Tianlai Pathfinder is designed to demonstrate the feasibility of using a wide field of view radio interferometers to map the density of neutral hydrogen in the Universe after t…
Sky reconstruction for the Tianlai cylinder array
Jiao Zhang, Shifan Zuo, Reza Ansari +5
In this paper, we apply our sky map reconstruction method for transit type interferometers to the Tianlai cylinder array. The method is based on the spherical harmonic decompositio…
