An Eigenvector-based Method of Radio Array Calibration and Its Application to the Tianlai Cylinder Pathfinder
Shifan Zuo, Ue-Li Pen, Fengquan Wu +4
We propose an eigenvector-based formalism for the calibration of radio interferometer arrays. In the presence of a strong dominant point source, the complex gains of the array can…
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…
An imaging algorithm for a lunar orbit interferometer array
Qizhi Huang, Shijie Sun, Shifan Zuo +5
Radio astronomical observation below 30 MHz is hampered by the refraction and absorption of the ionosphere, and the radio frequency interference (RFI), so far high angular resoluti…
21cm Signal Recovery via the Robust Principle Component Analysis
Shifan Zuo, Xuelei Chen, Reza Ansari +1
The redshifted 21~cm signal from neutral hydrogen (HI) is potentially a very powerful probe for cosmology, but a difficulty in its observation is that it is much weaker than foregr…
