An upgraded frequency-selectable laser source (FLS) calibrator for CMB bandpass characterization
Lauren J. Saunders, Sara M. Simon, Shreya Sutariya +4
One of the biggest challenges for Cosmic Microwave Background (CMB) experiments comes from the uncertainty in instrument bandpass calibration. Uncertainties in bandpass can limit f…
In-Band Scattering and Absorption of Infrared Blocking Foam Filters for Millimeter-wave Cameras
Alex Thomas, Bugao Zou, Shreya Sutariya +11
Expanded closed-cell polymer foams are widely used as thermal infrared (IR) blocking filters in millimeter-wave cameras, particularly for Cosmic Microwave Background observations.…
The Atacama Cosmology Telescope: A Test of the Gravitational Force Law on Cosmological Scales Using the Kinematic Sunyaev-Zeldovich Effect
Patricio A. Gallardo, Kris Pardo, Oliver H. E. Philcox +38
The mean pairwise velocity of massive halos reflects the gravitational force law on cosmic scales. We combine cosmic microwave background intensity maps from the Atacama Cosmology…
The Atacama Cosmology Telescope: A Measurement of the DR6 CMB Lensing Power Spectrum and its Implications for Structure Growth
Frank J. Qu, Blake D. Sherwin, Mathew S. Madhavacheril +155
We present new measurements of cosmic microwave background (CMB) lensing over sq. deg. of the sky. These lensing measurements are derived from the Atacama Cosmology Telescop…
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,…
The Simons Observatory: Characterization of All DC/RF Routing Wafers for Detector Modules
Alicia Middleton, Kyuyoung Bae, Cody J. Duell +11
The Simons Observatory (SO) is a cosmic microwave background experiment with over 67,000 polarization-sensitive transition-edge sensor (TES) detectors currently installed for use i…
