Implications of the Cosmic Background Imager Polarization Data

J. L. Sievers, C. Achermann, J. R. Bond +17

We present new measurements of the power spectra of the E-mode of CMB polarization, the temperature T, the cross-correlation of E and T, and upper limits on the B-mode from 2.5 yea…

Dust-correlated cm-wavelength continuum emission on translucent clouds ζ Oph and LDN 1780

M. Vidal, S. Casassus, C. Dickinson +17

The diffuse cm-wave IR-correlated signal, the "anomalous" CMB foreground, is thought to arise in the dust in cirrus clouds. We present Cosmic Background Imager (CBI) cm-wave data o…

Estimating Soil Electrical Parameters in the Canadian High Arctic from Impedance Measurements of the MIST Antenna Above the Surface

I. Hendricksen, R. A. Monsalve, V. Bidula +13

The MIST experiment aims to detect the cosmological 21-cm signal through sky observations at 25-125 MHz using a wide-beam antenna. The antenna is mounted above the soil and the bea…

Optimization of Antenna Performance for Global 21-cm Observations and Verification Using Scaled Copies

O. A. Restrepo, F. I. Lucero, G. Chaparro +5

The sky-averaged cosmological 21 cm signal can improve our understanding of the evolution of the early Universe from the Dark Age to the end of the Epoch of Reionization. Although…

The Simons Observatory: forecasted constraints on primordial gravitational waves with the expanded array of Small Aperture Telescopes

The Simons Observatory Collaboration, I. Abril-Cabezas, S. Adachi +479

We present updated forecasts for the scientific performance of the degree-scale (0.5 deg FWHM at 93 GHz), deep-field survey to be conducted by the Simons Observatory (SO). By 2027,…

CCAT-prime: Science with an Ultra-widefield Submillimeter Observatory at Cerro Chajnantor

G. J. Stacey, M. Aravena, K. Basu +37

We present the detailed science case, and brief descriptions of the telescope design, site, and first light instrument plans for a new ultra-wide field submillimeter observatory, C…
