Cosmological inference from emulator based halo model I: Validation tests with HSC and SDSS mock catalogs
Hironao Miyatake, Yosuke Kobayashi, Masahiro Takada +7
We present validation tests of emulator-based halo model method for cosmological parameter inference, assuming hypothetical measurements of the projected correlation function of ga…
Power Spectrum of Intrinsic Alignments of Galaxies in IllustrisTNG
Jingjing Shi, Toshiki Kurita, Masahiro Takada +3
We present the 3-{\it dimensional} intrinsic alignment power spectra between the projected 2d galaxy shape/spin and the 3d tidal field across using cosmo…
Validating a minimal galaxy bias method for cosmological parameter inference using HSC-SDSS mock catalogs
Sunao Sugiyama, Masahiro Takada, Yosuke Kobayashi +4
We assess the performance of a perturbation theory inspired method for inferring cosmological parameters from the joint measurements of galaxy-galaxy weak lensing () and the pr…
Accurate emulator for the redshift-space power spectrum of dark matter halos and its application to galaxy power spectrum
Yosuke Kobayashi, Takahiro Nishimichi, Masahiro Takada +2
An accurate theoretical template of the redshift-space galaxy power spectrum, if applicable out to nonlinear scales, enables us to extract more stringent and robust constraints on…
Power spectrum of halo intrinsic alignments in simulations
Toshiki Kurita, Masahiro Takada, Takahiro Nishimichi +3
We use a suite of -body simulations to study intrinsic alignments (IA) of halo shapes with the surrounding large-scale structure in the CDM model. For this purpose, we develo…
The impact of projection effects on cluster observables: stacked lensing and projected clustering
Tomomi Sunayama, Youngsoo Park, Masahiro Takada +6
An optical cluster finder inevitably suffers from projection effects, where it misidentifies a superposition of galaxies in multiple halos along the line-of-sight as a single clust…
