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…
ECoPANN: A Framework for Estimating Cosmological Parameters using Artificial Neural Networks
Guo-Jian Wang, Si-Yao Li, Jun-Qing Xia
In this work, we present a new method to estimate cosmological parameters accurately based on the artificial neural network (ANN), and a code called ECoPANN (Estimating Cosmologica…
Machine Learning the Cosmic Curvature in a Model-independent Way
Guo-Jian Wang, Xiao-Jiao Ma, Jun-Qing Xia
In this work, we achieve the determination of the cosmic curvature in a cosmological model-independent way, by using the Hubble parameter measurements and type Ia supe…
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…
