Reflections and Standing Waves on the Tianlai Cylinder Array
Jixia Li, Fengquan Wu, Shijie Sun +8
In 21~cm intensity mapping, the spectral smoothness of the foreground is exploited to separate it from the much weaker 21~cm signal. However, the non-smooth frequency response of t…

The Design and Implementation of a ROACH2+GPU based Correlator on the Tianlai Dish Array
Chenhui Niu, Qunxiong Wang, David MacMahon +7
The digital correlator is a crucial element in a modern radio telescope. In this paper we describe a scalable design of the correlator system for the Tianlai pathfinder array, whic…
