We review the physics and phenomenology of wave dark matter: a bosonic dark matter
candidate lighter than about 30 eV. Such particles have a de Broglie wavelength exceeding …

We review the landscape of QCD axion models. Theoretical constructions that extend the
window for the axion mass and couplings beyond conventional regions are highlighted and …

We search for ultra-light axions as dark matter (DM) and dark energy particle candidates, for
axion masses 10-32 eV≤ ma≤ 10-24 eV, by a joint analysis of cosmic microwave …

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 …

Ultralight axions and other bosons are dark matter candidates present in many high energy
physics theories beyond the Standard Model. In particular, the string axiverse postulates the …

In this work, we show that the Cold New Early Dark Energy (Cold NEDE) model in its original
form can solve both the Hubble tension and the S 8 tension without adding any new …

We study the dynamical properties of tracker quintessence models using a general
parametrization of their corresponding potentials, and show that there is a general condition …

Measurements of secondary cosmic microwave background (CMB) anisotropies, such as
the Sunyaev-Zel'dovich (SZ) effect, will enable new tests of neutrino and dark sector …

A bstract Massive scalar fields provide excellent dark matter candidates, whose dynamics
are often explored analytically and numerically using nonrelativistic Schrödinger-Poisson …

The main aim of this paper is to provide cosmological constraints on the multiscalar field
dark matter model, in which we assume the dark matter is made up of different ultralight …
