Kavli Affiliate: Joshua Frieman | Summary:We discuss the measurement of the Hubble constant ($H_0$) in flat $Λ$ cold dark matter cosmology based on the blind hierarchical analysis of 11 multiply-imaged quasars (hereafter the TDCOSMO-2026 sample) and described in greater detail in a companion paper. In addition to the time delays, we use lens models based […]
Kavli Affiliate: Joshua Frieman | Summary:We present cosmological constraints from 11 strongly lensed quasars with measured time delays (hereafter, the TDCOSMO-2026 sample). In addition to expanding the sample, we improve many aspects of our blind analysis with respect to our 2025 analysis. Among other improvements, spatially resolved kinematics are available for nine systems, including six […]
Kavli Affiliate: Young-kee Kim | Summary:A Muon Collider is one of the most attractive routes to multi-TeV lepton collisions, but it requires the accelerator and detector communities to solve a tightly coupled set of problems that have no close precedent in an operating collider. Muons must be produced, captured, cooled, accelerated, and collided before they […]
Kavli Affiliate: Daniel Kronauer | Authors: Daniel H. Pastor, Leonora Olivos-Cisneros, Alejandra Hurtado-Giraldo, Anurag Sharma, Patrick K. Piekarski, Giacomo L. Glotzer and Daniel Kronauer | Summary: Ant larvae are blind and immobile, depending heavily on the adults for care in the form of feeding, grooming, and transport. However, they are not inactive colony members but […]
Kavli Affiliate: Michael J Higley | Authors: Yongxu Zhang, Josue Ortega Caro, Rachel Oren, Michael James Higley, Jessica Cardin, Anne Churchland and Shreya Saxena | Summary: Modern recording technologies enable simultaneous measurement of high-dimensional neural activity and rich behavioral variables, creating both an opportunity and a modeling challenge: identifying the shared latent structure that mediates […]
Kavli Affiliate: David W. Miller | Summary:Gaia has substantially expanded the sample of candidate white dwarfs (WDs) in open clusters, but many remain without spectroscopic characterization. We leverage the increasingly extensive archives of large public spectroscopic surveys to identify 62 candidate cluster WDs with available spectra from DESI, LAMOST, and SDSS. After discarding sources with […]
Kavli Affiliate: Linhua Jiang | Summary:Emission-line galaxies provide key diagnostics of star formation, chemical enrichment, and AGN activity across cosmic time. We present a systematic census of emission-line sources using JWST/NIRCam wide-field slitless spectroscopy (WFSS) from the COSMOS-3D program, which covers a large contiguous area of 0.33 deg$^2$ and provides F444W grism spectroscopy over $3.9$–$5.1 […]
Kavli Affiliate: Anthony Lasenby | Summary:We investigate the local gravitational source and charges obtained by introducing translations as an internal Stückelberg redundancy in Weyl gauge theory. The internal-$T(4)$-invariant dressed coframe identifies the source of the translational potential with the existing coframe variational derivative, without introducing new dynamics. We derive an excitation/source equation and balance law […]
Kavli Affiliate: Anthony Lasenby | Summary:We consider whether the translation Noether current of a linearised metric spin-2 theory admits a strictly gauge-invariant local representative. For Fierz-Pauli and dynamically regular pure curvature-squared theories in four dimensions, we show that no such representative exists under the stated locality, polynomiality and covariance assumptions. A direct enumeration first excludes […]
Kavli Affiliate: Wei Gao| Summary:In the investigation of the "knee" region within the cosmic ray energy spectrum, extensive air shower (EAS) reconstruction by using different EAS secondary particles are of paramount importance for energy determination and composition separation and finally measurement of energy spectrum of different cosmic ray composition. The Electron-Neutron Detector Array (ENDA) is […]
