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…
E/B mode decomposition of HSC-Y1 cosmic shear using COSEBIs: cosmological constraints and comparison with other two-point statistics
Takashi Hamana, Chiaki Hikage, Masamune Oguri +2
We perform a cosmic shear analysis of HSC survey first-year data (HSC-Y1) using Complete Orthogonal Sets of E/B-Integrals (COSEBIs) to derive cosmological constraints. We compute E…
Cosmological inference from the emulator based halo model II: Joint analysis of galaxy-galaxy weak lensing and galaxy clustering from HSC-Y1 and SDSS
Hironao Miyatake, Sunao Sugiyama, Masahiro Takada +25
We present high-fidelity cosmology results from a blinded joint analysis of galaxy-galaxy weak lensing () and projected galaxy clustering () measured from the Hype…
HSC Year 1 cosmology results with the minimal bias method: HSCBOSS galaxy-galaxy weak lensing and BOSS galaxy clustering
Sunao Sugiyama, Masahiro Takada, Hironao Miyatake +23
We present cosmological parameter constraints from a blinded joint analysis of galaxy-galaxy weak lensing, , and projected correlation function, , measure…
Minkowski functionals and the nonlinear perturbation theory in the large-scale structure: second-order effects
Takahiko Matsubara, Chiaki Hikage, Satoshi Kuriki
The second-order formula of Minkowski functionals in weakly non-Gaussian fields is compared with the numerical -body simulations. Recently, weakly non-Gaussian formula of Minkow…
Covariance of the redshift-space matter power spectrum after reconstruction
Chiaki Hikage, Ryuichi Takahashi, Kazuya Koyama
We explore the covariance of redshift-space matter power spectra after a standard density-field reconstruction. We derive perturbative formula of the covariance at the tree-level o…
