Ultimate limits and prospects of long-baseline optical fiber interferometry

Kavli Affiliate: Nergis Mavalvala | First 5 Authors: Christopher Hilweg, Danial Shadmany, Philip Walther, Nergis Mavalvala, Vivishek Sudhir | Summary: Today’s most precise optical instruments — gravitational-wave interferometers and optical atomic clocks — rely on long storage times for photons to realize their exquisite sensitivity. Optical fiber technology is the most widely deployed platform for […]

Disentangled Representation with Causal Constraints for Counterfactual Fairness

Kavli Affiliate: Ke Wang | First 5 Authors: Ziqi Xu, Jixue Liu, Debo Cheng, Jiuyong Li, Lin Liu | Summary: Much research has been devoted to the problem of learning fair representations; however, they do not explicitly the relationship between latent representations. In many real-world applications, there may be causal relationships between latent representations. Furthermore, […]

Computational Fluid Dynamics with the Coupled Discrete Unified Gas Kinetic Scheme (CDUGKS)

Kavli Affiliate: Tom Abel | First 5 Authors: Alvaro Zamora, Tom Abel, , , | Summary: In this paper, we introduce our open source implementation of the Coupled Discrete Unified Gas Kinetic Scheme (CDUGKS) of https://journals.aps.org/pre/abstract/10.1103/PhysRevE.98.053310, a phase space scheme capable of handling a wide range of flow regimes. We demonstrate its performance on several […]

Alternating north-south brightness ratio of Ganymede’s auroral ovals: Hubble Space Telescope observations around the Juno PJ34 flyby

Kavli Affiliate: George Clark | First 5 Authors: Joachim Saur, Stefan Duling, Alexandre Wennmacher, Clarissa Willmes, Lorenz Roth | Summary: We report results of Hubble Space Telescope observations from Ganymede’s orbitally trailing side which were taken around the flyby of the Juno spacecraft on June 7, 2021. We find that Ganymede’s northern and southern auroral […]

The Photon Ring in M87*

Kavli Affiliate: Lijing Shao | First 5 Authors: Avery E. Broderick, Dominic W. Pesce, Paul Tiede, Hung-Yi Pu, Roman Gold | Summary: We report measurements of the gravitationally lensed secondary image — the first in an infinite series of so-called "photon rings" — around the supermassive black hole M87* via simultaneous modeling and imaging of […]

The Atacama Cosmology Telescope: limits on dark matter-baryon interactions from DR4 power spectra

Kavli Affiliate: Blake Sherwin | First 5 Authors: Zack Li, Rui An, Vera Gluscevic, Kimberly K. Boddy, J. Richard Bond | Summary: Diverse astrophysical observations suggest the existence of cold dark matter that interacts only gravitationally with radiation and ordinary baryonic matter. Any nonzero coupling between dark matter and baryons would provide a significant step […]

Measurement of the $Ω_c^0$ lifetime at Belle II

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, L. Aggarwal, H. Ahmed | Summary: We report on a measurement of the $Omega_c^0$ lifetime using $Omega_c^0 to Omega^-pi^+$ decays reconstructed in $e^+e^-to cbar{c}$ data collected by the Belle II experiment and corresponding to $207~{rm fb^{-1}}$ of integrated luminosity. The […]
