We present new measurements of cosmic microwave background (CMB) lensing over 9400
deg 2 of the sky. These lensing measurements are derived from the Atacama Cosmology …

The recent result of the Dark Energy Spectroscopic Instrument (DESI) in combination with
other cosmological data shows evidence of the evolving dark energy parametrized by the w …

We present a measurement of gravitational lensing over 1500 deg 2 of the Southern sky
using SPT-3G temperature data at 95 GHz and 150 GHz taken in 2018. The lensing …

We present cosmological results from the measurement of baryon acoustic oscillations
(BAO) in galaxy, quasar and Lyman-$\alpha $ forest tracers from the first year of …

Weak galaxy lensing surveys have consistently reported low values of the S 8 parameter
compared to the Planck lambda cold dark matter (ΛCDM) cosmology. Amon & Efstathiou …

We study the angular clustering of Quaia, a Gaia-and unWISE-based catalog of over a
million quasars with an exceptionally well-defined selection function. With it, we derive …

This paper introduces the class of omnipotent dark energy (DE) models characterized by
nonmonotonic energy densities that are capable of attaining negative values with …

Scalar field ϕ CDM models provide an alternative to the standard Λ CDM paradigm, while
being physically better motivated. Dynamical scalar field ϕ CDM models are divided into two …

In this work we present PRyMordial: A package dedicated to efficient computations of
observables in the Early Universe with the focus on the cosmological era of Big Bang …

The cosmic microwave background (CMB) temperature and polarization anisotropies, as
observed by independent astronomical missions such as WMAP, Planck, and most recently …
