In recent years, observations of the Sunyaev-Zeldovich (SZ) effect have had significant
cosmological implications and have begun to serve as a powerful and independent probe of …

This review covers the measurements related to the extragalactic background light intensity
from γ-rays to radio in the electromagnetic spectrum over 20 decades in wavelength. The …

We compare primordial black hole (PBH) constraints on the power spectrum and mass
distributions using the traditional Press Schechter formalism, peaks theory, and a recently …

This Voyage 2050 paper highlights the unique science opportunities using spectral
distortions of the cosmic microwave background (CMB). CMB spectral distortions probe …

We calculate the post-recombination contribution to the cosmic microwave background
(CMB) spectral distortion due to general exotic energy injections, including dark matter (DM) …

Deviations from the blackbody spectral energy distribution of the cosmic microwave
background (CMB) are a precise probe of physical processes active both in the early …

We forecast the scientific capabilities to improve our understanding of cosmic inflation of
CORE, a proposed CMB space satellite submitted in response to the ESA fifth call for a …

The recent detection of a stochastic gravitational wave background (SGWB) at nanohertz
frequencies by pulsar timing arrays (PTAs) has sparked a flurry of interest. Beyond the …

In the past few decades, the field of cosmology has undergone a period of dramatically rapid
progress in which a standard model of cosmology has emerged, ΛCDM. The precision with …

Spectral distortions (SDs) of the cosmic microwave background (CMB) provide a powerful
tool for studying particle physics. Here we compute the distortion signals from decaying …
