Design and Implementation of a Scalable Correlator Based on ROACH2+GPU Cluster for Tianlai 96-Dual-Polarization Antenna Array
Zhao Wang, Ji-Xia Li, Ke Zhang +7
The digital correlator is one of the most crucial data processing components of a radio telescope array. With the scale of radio interferometeric array growing, many efforts have b…
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…
Cosmological constraint on Brans-Dicke Model
Ji-Xia Li, Feng-Quan Wu, Yi-Chao Li +2
We combine new Cosmic Microwave Background (CMB) data from Planck with Baryon Acoustic Oscillation (BAO) data to constrain the Brans-Dicke (BD) theory, in which the gravitational c…
