Dish Assembly Precision for HIRAX
Jennifer Studer, Devin Crichton, Alexandre Refregier +16
The paper presents photogrammetry measurements of the first 28 HIRAX dishes, showing that dish surface deviations meet specifications while feed placement meets accuracy but not pr…
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,…
Primary Beam Chromaticity in HIRAX: I. Characterization from Simulations and Power Spectrum Implications
Ajith Sampath, Devin Crichton, Kavilan Moodley +15
The Hydrogen Intensity and Real-time Analysis eXperiment (HIRAX) is an upcoming radio interferometric telescope designed to constrain dark energy through the 21cm intensity mapping…
The Atacama Cosmology Telescope: DR6 Constraints on Extended Cosmological Models
Erminia Calabrese, J. Colin Hill, Hidde T. Jense +169
We use new cosmic microwave background (CMB) primary temperature and polarization anisotropy measurements from the Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) to test fo…
The Atacama Cosmology Telescope: DR6 Power Spectra, Likelihoods and CDM Parameters
Thibaut Louis, Adrien La Posta, Zachary Atkins +165
We present power spectra of the cosmic microwave background (CMB) anisotropy in temperature and polarization, measured from the Data Release 6 maps made from Atacama Cosmology Tele…
The Atacama Cosmology Telescope: DR6 Maps
Sigurd Naess, Yilun Guan, Adriaan J. Duivenvoorden +163
We present Atacama Cosmology Telescope (ACT) Data Release 6 (DR6) maps of the Cosmic Microwave Background temperature and polarization anisotropy at arcminute resolution over three…
