Constraints on primordial non-Gaussianity using multitracer technique for skew spectrum

Ji-Ping Dai, Jun-Qing Xia

Extracting the bispectrum information from the large scale structure observations is challenging due to the complex models and the computational costs to measure the signal and its…

Impacts of the simulated standard siren on estimating cosmological parameters

Dong Zhao, Zhi-Chao Zhao, Jun-Qing Xia

We propose a method based on the process of extracting gravitational wave (GW) parameters from GW signals to simulate the binary neutron-star (BNS) merging events. We simulate 1000…

Searching for Integrated Sachs-Wolfe Effect from Fermi-LAT Diffuse -ray Map

Xiu-Hui Tan, Ji-Ping Dai, Jun-Qing Xia

In this paper, we estimate the cross-correlation power spectra between the Planck 2018 cosmic microwave background (CMB) temperature anisotropy map and the unresolved -ray backg…

Reconstruction of Reionization History through Dispersion Measure of Fast Radio Bursts

Ji-Ping Dai, Jun-Qing Xia

In this paper, we study the evolution of the ionization fraction during the epoch of reionization by using the dispersion measurements (DMs) of fast radio bursts (FRBs). D…
