Nearly-zero large-angle anisotropy of the cosmic microwave background

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen | Summary: The global isotropy of the universe is analyzed on the scale of the cosmic horizon, using the angular correlation function $C(Theta)$ of cosmic microwave background (CMB) temperature at large angular separation $Theta$. Even-parity correlation […]

Nearly-zero large-angle anisotropy of the cosmic microwave background

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Stephan S. Meyer, Nathaniel Selub, Frederick Wehlen | Summary: Anisotropy of space-time is measured on the scale of the cosmic horizon, using the angular correlation function $C(Theta)$ of cosmic microwave background (CMB) temperature at large angular separation $Theta$. Even-parity correlation $C_{rm even}(Theta)$ is […]

Flux coupled tunable superconducting resonator

Kavli Affiliate: Clarence Chang | First 5 Authors: Juliang Li, Pete Barry, Tom Cecil, Marharyta Lisovenko, Volodymyr Yefremenko | Summary: We present a design and implementation of frequency-tunable superconducting resonator. The resonance frequency tunability is achieved by flux-coupling a superconducting LC-loop to a current-biased feedline; the resulting screening current leads to a change of the […]

A New Probe of Gravitational Parity Violation Through (Non-)Observation of the Stochastic Gravitational-Wave Background

Kavli Affiliate: Daniel Holz | First 5 Authors: Thomas Callister, Leah Jenks, Daniel Holz, Nicolás Yunes, | Summary: Parity violation in the gravitational sector is a prediction of many theories beyond general relativity. In the propagation of gravitational waves, parity violation manifests by inducing amplitude and/or velocity birefringence between right- and left-circularly polarized modes. We […]

DeepSurveySim: Simulation Software and Benchmark Challenges for Astronomical Observation Scheduling

Kavli Affiliate: Brian Nord | First 5 Authors: Maggie Voetberg, Brian Nord, , , | Summary: Modern astronomical surveys have multiple competing scientific goals. Optimizing the observation schedule for these goals presents significant computational and theoretical challenges, and state-of-the-art methods rely on expensive human inspection of simulated telescope schedules. Automated methods, such as reinforcement learning, […]

Cosmological gravitational particle production and its implications for cosmological relics

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Edward W. Kolb, Andrew J. Long, , , | Summary: Cosmological gravitational particle production (CGPP) is the creation of particles in an expanding universe due solely to their gravitational interaction. These particles can play an important role in the cosmic history through their connection to various […]
