Phenomenological Modeling of the Ho Calorimetric Electron Capture Spectrum from the HOLMES Experiment
F. Ahrens, B. K. Alpert, D. T. Becker +46
We present a comprehensive phenomenological analysis of the calorimetric electron capture (EC) decay spectrum of Ho as measured by the HOLMES experiment. Using high-statist…
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,…
Demonstration of a 1820 channel multiplexer for transition-edge sensor bolometers
J. C. Groh, Z. Ahmed, J. Austermann +16
The scalability of most transition-edge sensor arrays is limited by the multiplexing technology which combines their signals over a reduced number of wires and amplifiers. In this…
Most stringent bound on electron neutrino mass obtained with a scalable low temperature microcalorimeter array
B. K. Alpert, M. Balata, D. T. Becker +36
The determination of the absolute neutrino mass scale remains a fundamental open question in particle physics, with profound implications for both the Standard Model and cosmology.…
The Simons Observatory: Science Goals and Forecasts for the Enhanced Large Aperture Telescope
The Simons Observatory Collaboration, M. Abitbol, I. Abril-Cabezas +419
We describe updated scientific goals for the wide-field, millimeter-wave survey that will be produced by the Simons Observatory (SO). Significant upgrades to the 6-meter SO Large A…
Noise limits for dc SQUID readout of high- resonators below 300 MHz
V. Ankel, C. Bartram, J. Begin +38
We present the limits on noise for the readout of cryogenic high- resonators using dc Superconducting Quantum Interference Devices (SQUIDs) below 300 MHz. This analysis uses rea…
