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 …

Abstract The Laser Interferometer Space Antenna (LISA) has the potential to reveal wonders
about the fundamental theory of nature at play in the extreme gravity regime, where the …

The simplest ΛCDM model provides a good fit to a large span of cosmological data but
harbors large areas of phenomenology and ignorance. With the improvement of the number …

Pulsar timing arrays (PTAs) have reported evidence for a stochastic gravitational wave (GW)
background at nanohertz frequencies, possibly originating in the early Universe. We show …

Euclid is a mission of the European Space Agency that is designed to constrain the
properties of dark energy and gravity via weak gravitational lensing and galaxy clustering. It …

The difference from 4 to 6 σ in the Hubble constant (H 0) between the values observed with
the local (Cepheids and Supernovae Ia, SNe Ia) and the high-z probes (Cosmic Microwave …

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 …

Abstract The Very Large Array Sky Survey (VLASS) is a synoptic, all-sky radio sky survey
with a unique combination of high angular resolution (≈ 2 farcs 5), sensitivity (a 1σ goal of …

The European Space Agency's Planck satellite, which was dedicated to studying the early
Universe and its subsequent evolution, was launched on 14 May 2009. It scanned the …

We use redshift-space galaxy clustering data from the BOSS survey to constrain local
primordial non-Gaussianity (LPNG). This is of particular importance due to the consistency …
