Cross-correlating galaxies and cosmic dispersion measures: Constraints on the gas-to-halo mass relation from 2MASS galaxies and 133 localized fast radio bursts
Masato Shirasaki, Ryuichi Takahashi, Ken Osato +1
We conduct a cross-correlation analysis between large-scale structures traced by the Two Micron All Sky Survey (2MASS) galaxy catalog and the cosmic dispersion measures of 133 loca…
Measurement of angular cross-correlation between the cosmological dispersion measure and the thermal Sunyaev--Zeldovich effect
Ryuichi Takahashi, Kunihito Ioka, Masato Shirasaki +1
The dispersion measures () from fast radio bursts (FRBs) and the thermal Sunyaev--Zeldovich (tSZ) effect probe the free-electron density and thermal pressure, respective…
Measuring the redshift-space distortions by cross-correlating the density fields before and after reconstruction
Weibing Zhang, Ruiyang Zhao, Xiaoyong Mu +4
In this work, we develop a theoretical model for the cross-power spectrum of the galaxy density field before and after standard baryonic acoustic oscillation (BAO) reconstruction.…
A cosmological full-shape power spectra analysis using pre- and post-reconstructed density fields
Weibing Zhang, Ruiyang Zhao, Xiaoyong Mu +4
In this work, we investigate a joint fitting approach based on theoretical models of power spectra associated with density-field reconstruction. Specifically, we consider the matte…
Impact of lensing bias on the cosmological dispersion measure
Ryuichi Takahashi
The cosmological dispersion measure (DM) as a function of redshift, derived from localized fast radio bursts (FRBs), has been used as a tool for constraining the cosmic ionized fra…
Extracting high-order cosmological information in galaxy surveys with power spectra
Yuting Wang, Gong-Bo Zhao, Kazuya Koyama +11
The reconstruction method was proposed more than a decade ago to boost the signal of baryonic acoustic oscillations measured in galaxy redshift surveys, which is one of key probes…
