Determining the origin of structure in the universe is one of the most important open
problems in cosmology. CMB anisotropies sourced by early-universe density perturbations …

Spectral features in the CMB energy spectrum contain a wealth of information about the
physical processes in the early Universe, z≲ 2× 106. The CMB spectral distortions are …

We point out two ways to search for low-mass axion dark matter using cosmic microwave
background (CMB) polarization measurements. These appear, in particular, to be some of …

The energy spectrum of the cosmic microwave background (CMB) allows us to constrain
episodes of energy release in the early Universe. In this paper, we revisit and refine …

Abstract PRISM (Polarized Radiation Imaging and Spectroscopy Mission) was proposed to
ESA in May 2013 as a large-class mission for investigating within the framework of the ESA …

ABSTRACT We use South Pole Telescope data from 2008 and 2009 to detect the non-
Gaussian signature in the cosmic microwave background (CMB) produced by gravitational …

Silicon platelet corrugated feedhorn arrays for cosmic microwave background (CMB)
measurements at millimeter wavelengths (130 GHz to 170 GHz) have been developed for …

The six-meter Atacama Cosmology Telescope (ACT) in Chile was built to measure the
cosmic microwave background (CMB) at arcminute angular scales. We are building a new …

The cosmic microwave background (CMB) provides us with our most direct observational
window to the early universe. Observations of the temperature and polarization anisotropies …

We present constraints on cosmological parameters based on a sample of Sunyaev–
Zel'dovich-selected (SZ-selected) galaxy clusters detected in a millimeter-wave survey by …
