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 …

Dark matter interactions with electrons or protons during the early Universe leave imprints
on the cosmic microwave background and the matter power spectrum, and can be probed …

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 study the distortions of equilibrium spectra of relic neutrinos due to the interactions with
electrons, positrons, and neutrinos in the early Universe. We solve the integro-differential …

The last decade has seen unprecedented effort in dark matter model building at all mass
scales coupled with the design of numerous new detection strategies. Transformative …

New light states thermally coupled to the Standard Model plasma alter the expansion history
of the Universe and impact the synthesis of the primordial light elements. In this work, we …

Precision measurements of the number of effective relativistic neutrino species and the
primordial element abundances require accurate theoretical predictions for early Universe …

We explore three sets of cosmological hydrodynamical simulations, IllustrisTNG (TNG50,
TNG100, and TNG300), EAGLE, and SIMBA, to investigate the physical processes impacting …

Environment is one of the primary drivers of galaxy evolution; via multiple mechanisms, it
can control the critical process of transforming galaxies from star forming to quiescent …

Gravitational weak lensing by dark matter haloes leads to a measurable imprint in the shear
correlation function of galaxies. Fuzzy dark matter (FDM), composed of ultralight axion-like …
