Abstract The Laser Interferometer Space Antenna (LISA) has two scientific objectives of
cosmological focus: to probe the expansion rate of the universe, and to understand …

The discovery of cosmic acceleration has triggered a consistent body of theoretical work
aimed at modeling its phenomenology and understanding its fundamental physical nature …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

We present CosmoPower, a suite of neural cosmological power spectrum emulators
providing orders-of-magnitude acceleration for parameter estimation from two-point statistics …

We present constraints on extensions to the standard cosmological model of a spatially flat
Universe governed by general relativity, a cosmological constant (Λ), and cold dark matter …

In this paper, we analyze the light rays around a static hairy black hole in Horndeski gravity
with the use of ray-tracing procedure. We find that a stronger Horndeski hairy parameter …

Abstract Several interesting Dark Matter (DM) models invoke a dark sector leading to two
types of relic particles, possibly interacting with each other: non-relativistic DM, and …

We investigate the synergy of upcoming galaxy surveys and gravitational wave (GW)
experiments in constraining late-time cosmology, examining the cross-correlations between …

ABSTRACT In Galaxy And Mass Assembly Data Release 4 (GAMA DR4), we make
available our full spectroscopic redshift sample. This includes 248 682 galaxy spectra, and …

Positivity bounds—constraints on any low-energy effective field theory imposed by the
fundamental axioms of unitarity, causality and locality in the UV—have recently been used to …
