Kavli Affiliate: Toshiya Namikawa | First 5 Authors: Hongbo Cai, Yilun Guan, Toshiya Namikawa, Arthur Kosowsky, | Summary: The power spectrum of cosmic microwave background lensing is a powerful tool for constraining fundamental physics such as the sum of neutrino masses and the dark energy equation of state. Current lensing measurements primarily come from distortions […]
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: Risa H. Wechsler | First 5 Authors: Alex Drlica-Wagner, Chanda Prescod-Weinstein, Hai-Bo Yu, Andrea Albert, Arka Banerjee | Summary: Cosmological and astrophysical observations currently provide the the only robust, positive evidence for dark matter. Cosmic probes of dark matter, which seek to determine the fundamental properties of dark matter through observations of the […]
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: Huawei Zhang | First 5 Authors: Gaochao Liu, Yang Huang, Sarah Ann Bird, Huawei Zhang, Fei Wang | Summary: Based on a large spectroscopic sample of $sim$ 4,300 RR Lyrae stars with metallicity, systemic radial velocity and distance measurements, we present a detailed analysis of the chemical and kinematic properties of the Galactic […]
