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 …

We generalize the recently proposed Stepped Partially Acoustic Dark Matter (SPartAcous)
model by including additional massless degrees of freedom in the dark radiation sector. We …

This is a solicited whitepaper for the Snowmass 2021 community planning exercise. The
paper focuses on measurements and science with the Cosmic Microwave Background …

Context. The Atacama Large Millimeter/submillimeter Array (ALMA) has been in operation
since 2011, but it has not yet been populated with the full suite of its planned frequency …

We present an overview of future observational facilities that will significantly enhance our
understanding of the fundamental nature of dark matter. These facilities span a range of …

Velocity fields can be reconstructed at cosmological scales from their influence on the
correlation between the cosmic microwave background and large-scale structure. Effects …

CMB-HD is a proposed millimeter-wave survey over half the sky that would be ultra-deep
(0.5 uK-arcmin) and have unprecedented resolution (15 arcseconds at 150 GHz). Such a …

The coldest and densest structures of gas and dust in the Universe have unique spectral
signatures across the (sub-) millimetre bands (υ≈ 30-950 GHz). The current generation of …

A bstract We argue that the striking similarity between the cosmic abundances of baryons
and dark matter, despite their very different astrophysical behavior, strongly motivates the …
