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 […]
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 […]

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 […]
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 $lambda6355$ […]
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 […]
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Stefania Gori, Mike Williams, Phil Ilten, Nhan Tran, Gordan Krnjaic | Summary: Is Dark Matter part of a Dark Sector? The possibility of a dark sector neutral under Standard Model (SM) forces furnishes an attractive explanation for the existence of Dark Matter (DM), and is a compelling […]
Kavli Affiliate: Michael D. Gladders | First 5 Authors: Michael N. Martinez, Kate A. Napier, Aidan P. Cloonan, Ezra Sukay, Katya Gozman | Summary: In the third paper from the COOL-LAMPS Collaboration, we report the discovery of COOL J0542-2125, a gravitationally lensed quasar at $z=1.84$, observed as three images due to an intervening massive galaxy […]
