Constraining Quintessence Models with ISW-tSZ Cross-Correlations: A Comparative Analysis of Thawing, Tracker, and Scaling-Freezing Dynamics
Ayodeji Ibitoye, Shiriny Akthar, Md. Wali Hossain +5
We present constraints on quintessence dark energy models using the observational detection of the Integrated Sachs-Wolfe (ISW)--thermal Sunyaev-Zeldovich (tSZ) cross-correlation d…
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…
A simulation of calibration and map-making errors of the Tianlai cylinder pathfinder array
Kaifeng Yu, Fengquan Wu, Shifan Zuo +4
The Tianlai cylinder array is a pathfinder for developing and testing 21cm intensity mapping techniques. In this paper, we use numerical simulation to assess how its measurement is…
Mapping the Milky Way's stellar halo with 2D data
Anda Chen, Zhigang Li, Yougang Wang +3
We propose a new method for measuring the spatial density distribution of the stellar halo of the Milky Way. Our method is based on a pairwise statistic of the distribution of star…
The 21-cm forest as a simultaneous probe of dark matter and cosmic heating history
Yue Shao, Yidong Xu, Yougang Wang +4
The absorption features in spectra of high-redshift background radio sources, caused by hyperfine structure lines of hydrogen atoms in the intervening structures, are known collect…
A Scalable Arrangement Method for Aperiodic Array Antennas to Reduce Peak Sidelobe Level
Jiao Zhang, Hongtao Zhang, Xuelei Chen +3
Peak sidelobe level reduction (PSLR) is crucial in the application of large-scale array antenna, which directly determines the radiation performance of array antenna. We study the…
