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…
Angular clustering and host halo properties of [OII] emitters at in the Subaru HSC survey
Teppei Okumura, Masao Hayashi, I-Non Chiu +4
We study the angular correlation function of star-forming galaxies and properties of their host dark matter halos at z>1 using the Hyper-Suprime Cam (HSC) SSP survey. We use [OII]…
TNG: Effect of Baryonic Processes on Weak Lensing with IllustrisTNG Simulations
Ken Osato, Jia Liu, Zoltán Haiman
We study the effect of baryonic processes on weak lensing (WL) observables with a suite of mock WL maps, the TNG, based on the cosmological hydrodynamic simulations IllustrisTNG…
Super-sample covariance of the thermal Sunyaev-Zel'dovich effect
Ken Osato, Masahiro Takada
The thermal Sunyaev-Zel'dovich (tSZ) effect is a powerful probe of cosmology. The statistical errors in the tSZ power spectrum measurements are dominated by the presence of massive…
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…
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…
The splashback radius of optically selected clusters with Subaru HSC Second Public Data Release
Ryoma Murata, Tomomi Sunayama, Masamune Oguri +4
Recent constraints on the splashback radius around optically selected galaxy clusters from the redMaPPer cluster-finding algorithm in the literature have shown that the observed sp…
