Abstract Hyper Suprime-Cam (HSC) is a wide-field imaging camera on the prime focus of
the 8.2-m Subaru telescope on the summit of Mauna Kea in Hawaii. A team of scientists from …

Despite its continued observational successes, there is a persistent (and growing) interest in
extending cosmology beyond the standard model, Λ CDM. This is motivated by a range of …

We report results from the BICEP2 experiment, a cosmic microwave background (CMB)
polarimeter specifically designed to search for the signal of inflationary gravitational waves …

The past two decades have seen transformative advances in cosmology and string theory.
Observations of the cosmic microwave background have revealed strong evidence for …

The accelerating expansion of the universe is the most surprising cosmological discovery in
many decades, implying that the universe is dominated by some form of “dark energy” with …

The bulk of cosmic matter resides in a dilute reservoir that fills the space between galaxies,
the intergalactic medium (IGM). The history of this reservoir is intimately tied to the cosmic …

Advanced ACTPol is a polarization-sensitive upgrade for the 6 m aperture Atacama
Cosmology Telescope, adding new frequencies and increasing sensitivity over the previous …

We describe the design of a new polarization sensitive receiver, spt-3g, for the 10-meter
South Pole Telescope (spt). The spt-3g receiver will deliver a factor of~ 20 improvement in …

The polarized thermal emission from diffuse Galactic dust is the main foreground present in
measurements of the polarization of the cosmic microwave background (CMB) at …
