Local and Covariant Flow Relations for OPE Coefficients in Lorentzian Spacetimes

Kavli Affiliate: Robert M. Wald | First 5 Authors: Mark G. Klehfoth, Robert M. Wald, , , | Summary: For Euclidean quantum field theories, Holland and Hollands have shown operator product expansion (OPE) coefficients satisfy "flow equations": For interaction parameter $lambda$, the partial derivative of any OPE coefficient with respect to $lambda$ is given by […]

Report of the Topical Group on Dark Energy and Cosmic Acceleration: Complementarity of Probes and New Facilities for Snowmass 2021

Kavli Affiliate: Lindsey E. Bleem | First 5 Authors: Brenna Flaugher, Vivian Miranda, David J. Schlegel, Adam J. Anderson, Felipe Andrade-Oliveira | Summary: The mechanism(s) driving the early- and late-time accelerated expansion of the Universe represent one of the most compelling mysteries in fundamental physics today. The path to understanding the causes of early- and […]

Milky Way Zero-Point Calibration of the JAGB Method: Using Thermally Pulsing AGB Stars in Galactic Open Clusters

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Barry F. Madore, Wendy L. Freedman, Abigail J. Lee, Kayla Owens, | Summary: We present a new calibration of the J-band absolute magnitude of the JAGB method based on thermally pulsing AGB stars that are members of Milky Way open clusters, having distances and reddenings, independently […]

The Absolute Magnitudes of 1991T-like Supernovae

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: M. M. Phillips, C. Ashall, Christopher R. Burns, Carlos Contreras, L. Galbany | Summary: 1991T-like supernovae are the luminous, slow-declining extreme of the Branch shallow-silicon (SS) subclass of Type Ia supernovae. They are distinguished by extremely weak Ca II H & K and Si II $lambda6355$ […]

Noise2Astro: Astronomical Image Denoising With Self-Supervised NeuralNetworks

Kavli Affiliate: Brian Nord | First 5 Authors: Yunchong Zhang, Brian Nord, Amanda Pagul, Michael Lepori, | Summary: In observational astronomy, noise obscures signals of interest. Large-scale astronomical surveys are growing in size and complexity, which will produce more data and increase the workload of data processing. Developing automated tools, such as convolutional neural networks […]
