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 …

Ultra-light dark matter is a class of dark matter models (DM), where DM is composed by
bosons with masses ranging from 10^-24\, eV< m< eV 10-24 eV< m< eV. These models …

We present a new bound on the ultralight axion (ULA) dark matter mass ma, using the
Lyman-alpha forest to look for suppressed cosmic structure growth: a 95% lower limit ma> …

Optimal extraction of the non-Gaussian information encoded in the large-scale structure of
the Universe lies at the forefront of modern precision cosmology. We propose achieving this …

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 …

While astrophysical and cosmological probes provide a remarkably precise and consistent
picture of the quantity and general properties of dark matter, its fundamental nature remains …

We perform the first application of the wavelet scattering transform (WST) to actual galaxy
observations, through a WST analysis of the BOSS DR12 CMASS dataset. We included the …

The cold dark-matter model successfully explains both the emergence and evolution of
cosmic structures on large scales and, when we include a cosmological constant, the …

Abstract Primordial Black Holes (PBHs) are a viable candidate to comprise some or all of the
dark matter and provide a unique window into the high-energy physics of the early universe …
