Cosmology and Source Redshift Constraints from Galaxy Clustering and Tomographic Weak Lensing with HSC Y3 and SDSS using the Point-Mass Correction Model
Tianqing Zhang, Xiangchong Li, Sunao Sugiyama +13
The combination of galaxy clustering and weak lensing is a powerful probe of the cosmology model. We present a joint analysis of galaxy clustering and weak lensing cosmology using…
Modelling Galaxy Clustering and Tomographic Galaxy-Galaxy Lensing with HSC Y3 and SDSS using the Point-Mass Correction Model and Redshift Self-Calibration
Tianqing Zhang, Sunao Sugiyama, Surhud More +13
The combination of galaxy-galaxy weak lensing and galaxy clustering is a powerful probe of the cosmological model, and exploration of how to best model and extract this information…
Renormalized Perturbation Theory at Field-level: the LSS bootstrap in GridSPT
Matteo Peron, Takahiro Nishimichi, Massimo Pietroni +1
We present a first step toward field-level cosmological inference beyond the standard CDM model, focusing on optimizing precision tests in the nonlinear regime of large-scale st…
SHAPE: cosmology with cluster halo intrinsic alignments from subhalo distributions
Shogo Ishikawa, Atsushi Taruya, Takahiro Nishimichi +2
Galaxy clusters trace the most massive dark matter haloes, whose shapes and orientations reflect the imprint of the cosmic large-scale tidal field. This paper introduces the Subhal…
