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…
Distinguishing between CDM and gravity models using halo ellipticity correlations in simulations
Yao-Tsung Chuang, Teppei Okumura, Masato Shirasaki
There is a growing interest in utilizing intrinsic alignment (IA) of galaxy shapes as a geometric and dynamical probe of cosmology. In this paper we present the first measurements…
Virial halo mass function in the cosmology
Masato Shirasaki, Tomoaki Ishiyama, Shin'ichiro Ando
We study halo mass functions with high-resolution -body simulations under a CDM cosmology. Our simulations adopt the cosmological model that is consistent with recent measure…
Probing cosmology and gastrophysics with fast radio bursts: Cross-correlations of dark matter haloes and cosmic dispersion measures
Masato Shirasaki, Ryuichi Takahashi, Ken Osato +1
For future surveys of fast radio bursts (FRBs), we clarify information available from cosmic dispersion measures (DMs) through cross-correlation analyses of foreground dark matter…
The three-year shear catalog of the Subaru Hyper Suprime-Cam SSP Survey
Xiangchong Li, Hironao Miyatake, Wentao Luo +15
We present the galaxy shear catalog that will be used for the three-year cosmological weak gravitational lensing analyses using data from the Wide layer of the Hyper Suprime-Cam (H…
Subaru Hyper Suprime-Cam excavates colossal over- and under-dense structures over 360 deg2 out to z=1
Rhythm Shimakawa, Yuichi Higuchi, Masato Shirasaki +8
Subaru Strategic Program with the Hyper-Suprime Cam (HSC-SSP) has proven to be successful with its extremely-wide area coverage in past years. Taking advantages of this feature, we…
Searching for eV-mass Axion-like Particles with Cross Correlations between Line Intensity and Weak Lensing Maps
Masato Shirasaki
We study cross correlations between line intensity and weak lensing maps to search for axion-like particles (ALPs). Radiative decay of eV-mass ALPs can contribute to cosmic backgro…
Stacked phase-space density of galaxies around massive clusters: Comparison of dynamical and lensing masses
Masato Shirasaki, Eiichi Egami, Nobuhiro Okabe +1
We present a measurement of average histograms of line-of-sight velocities over pairs of galaxies and galaxy clusters. Since the histogram can be measured at different galaxy-clust…
