Probing the Cosmological Principle with the CSST Photometric Survey
Yu-Tian Xu, Ji-Ping Dai, Dong Zhao +1
The cosmological principle states that our Universe is statistically homogeneous and isotropic at large scales. However, due to the relative motion of the Solar System, an addition…
Reconstruction of Baryon Fraction in Intergalactic Medium through Dispersion Measurements of Fast Radio Bursts
Ji-Ping Dai, Jun-Qing Xia
Fast radio bursts (FRBs) probe the total column density of free electrons in the intergalactic medium (IGM) along the path of propagation though the dispersion measures (DMs) which…
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…
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…
Constraints on Running of Non-Gaussianity from Large Scale Structure Probes
Ji-Ping Dai, Jun-Qing Xia
In this letter we present constraints on the scale-dependent "local" type primordial non-Gaussianity, which is described by non-Gaussianity's spectral index , from the…
