Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

We measure weak lensing cosmic shear power spectra from the 3-year galaxy shear catalog
of the Hyper Suprime-Cam (HSC) Subaru Strategic Program imaging survey. The shear …

We perform a blinded cosmology analysis with cosmic shear two-point correlation functions
measured from more than 25 million galaxies in the Hyper Suprime-Cam three-year shear …

We study the comoving curvature perturbation R in the single-field inflation models whose
potential can be approximated by a piecewise quadratic potential V (φ) by using the δ N …

We explore the role of redshift-space galaxy clustering data in constraining nongravitational
interactions between dark energy (DE) and dark matter (DM), for which state-of-the-art limits …

We use updated type Ia Pantheon+ supernova, baryon acoustic oscillation, and Hubble
parameter (now also accounting for correlations) data, as well as new reverberation …

We use luminous red galaxies selected from the imaging surveys that are being used for
targeting by the Dark Energy Spectroscopic Instrument (DESI) in combination with CMB …

Current cosmological data exhibit discordance between indirect and some direct inferences
of the present-day expansion rate H 0. Early dark energy (EDE), which briefly increases the …

We analyze the properties that any late-time modification of the Λ CDM expansion history
must have in order to consistently solve both the H 0 and the σ 8 tensions. Taking a model …

We use the state-of-the-art data on cosmic chronometers (CCH) and the Pantheon+
compilation of supernovae of Type Ia (SNIa) to test the constancy of the SNIa absolute …
