Abstract 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 for dark energy. After moving the observed overdensities in g

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 for dark energy. After moving the observed overdensities in galaxy

Minkowski functionals and the nonlinear perturbation theory in the large-scale structure: Second-order effects
Autor: Takahiko Matsubara, Chiaki Hikage, Satoshi Kuriki
Publikováno v: Physical Review D. 105
The second-order formula of Minkowski functionals in weakly non-Gaussian fields is compared with the numerical $N$-body simulations. Recently, weakly non-Gaussian formula of Minkowski functionals is extended to include the second-order effects of non

Perturbation theory for the redshift-space matter power spectra after reconstruction
Autor: Chiaki Hikage, Kazuya Koyama, Ryuichi Takahashi
Publikováno v: Hikage, C, Koyama, K & Takahashi, R 2020, ' Perturbation theory for the redshift-space matter power spectra after reconstruction ', Physical Review D-Particles, Fields, Gravitation and Cosmology, vol. 101, no. 4, 043510 . https://doi.org/10.1103/PhysRevD.101.043510
Physical Review D
We derive the one-loop perturbative formula of the redshift-space matter power spectrum after density field reconstruction in the Zeldovich approximation. We find that the reconstruction reduces the amplitudes of nonlinear one-loop perturbative terms

New constraints on the mass bias of galaxy clusters from the power spectra of the thermal Sunyaev–Zeldovich effect and cosmic shear
Autor: Eiichiro Komatsu, Chiaki Hikage, Ryu Makiya
Publikováno v: Publications of the Astronomical Society of Japan. 72
Thermal Sunyaev-Zeldovich (tSZ) power spectrum is a powerful probe of the present-day amplitude of matter density fluctuations, and has been measured up to $\ell\approx 10^3$ from the {\it Planck} data. The largest systematic uncertainty in the inter
