Cross-Section Continuity of Definitions of Angular Momentum

Kavli Affiliate: Robert M. Wald | First 5 Authors: Po-Ning Chen, Daniel Paraizo, Robert M. Wald, Mu-Tao Wang, Ye-Kai Wang | Summary: We introduce a notion of "cross-section continuity" as a criterion for the viability of definitions of angular momentum, $J$, at null infinity: If a sequence of cross-sections, ${mathcal C}_n$, of null infinity converges […]

Large-scale capture of hidden fluorescent labels for training generalizable markerless motion capture models

Kavli Affiliate: Eiman Azim | Authors: Daniel J Butler, Alexander P Keim, Shantanu Ray and Eiman Azim | Summary: Recent advances in deep learning-based markerless pose estimation have dramatically improved the scale and ease with which body landmarks can be tracked in studies of animal behavior. However, pose estimation for animals in a laboratory setting […]

High quantum efficiency parametric amplification via hybridized nonlinear optics

Kavli Affiliate: Jeffrey Moses | Summary:Parametric amplifiers have allowed breakthroughs in ultrafast, strong-field, and high-energy density laser science and are an essential tool for extending the frequency range of powerful emerging diode-pumped solid-state laser technology. However, their impact is limited by inherently low quantum efficiency due to nonuniform light extraction. Here we demonstrate a new […]

Chemical Abundances of the Typhon Stellar Stream

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Alexander P. Ji, Rohan P. Naidu, Kaley Brauer, Yuan-Sen Ting, Joshua D. Simon | Summary: We present the first high-resolution chemical abundances of seven stars in the recently discovered high-energy dwarf galaxy stream Typhon. Typhon stars have apocenters reaching to ${gtrsim}100$ kpc, making this the first […]
