Optical design concept of the CMB-S4 large-aperture telescopes and cameras

Kavli Affiliate: Bradford Benson | First 5 Authors: Patricio A. Gallardo, Bradford Benson, John Carlstrom, Simon R. Dicker, Nick Emerson | Summary: CMB-S4 — the next-generation ground-based cosmic microwave background (CMB) experiment – will significantly advance the sensitivity of CMB measurements and improve our understanding of the origin and evolution of the universe. CMB-S4 will […]

On the origin of radio-loudness in active galactic nuclei using far-infrared polarimetric observations

Kavli Affiliate: Roger Blandford | First 5 Authors: Enrique Lopez-Rodriguez, Makoto Kishimoto, Robert Antonucci, Mitchell C. Begelman, Noemie Globus | Summary: The dichotomy between radio-loud (RL) and radio-quiet (RQ) active galactic nuclei (AGN) is thought to be intrinsically related to radio jet production. This difference may be explained by the presence of a strong magnetic […]

The Precision nEDM Measurement with UltraCold Neutrons at TRIUMF

Kavli Affiliate: Eric Miller | First 5 Authors: Ryohei Matsumiya, Hiroaki Akatsuka, Chris P. Bidinosti, Charles A. Davis, Beatrice Franke | Summary: The TRIUMF Ultra-Cold Advanced Neutron (TUCAN) collaboration aims at a precision neutron electric dipole moment (nEDM) measurement with an uncertainty of $10^{-27},ecdotmathrm{cm}$, which is an order-of-magnitude better than the current nEDM upper limit […]

Gaia Spectroscopic Orbits Validated with LAMOST and GALAH Radial Velocities

Kavli Affiliate: Subo Dong | First 5 Authors: Dolev Bashi, Sahar Shahaf, Tsevi Mazeh, Simchon Faigler, Subo Dong | Summary: The recently published Gaia DR3 catalog of 181 327 spectroscopic binaries (SB) includes the Keplerian elements of each orbit, but not the measured radial velocities (RVs) and their epochs themselves. Instead, the catalog lists a […]

On Scheduling Ring-All-Reduce Learning Jobs in Multi-Tenant GPU Clusters with Communication Contention

Kavli Affiliate: Jia Liu | First 5 Authors: Menglu Yu, Bo Ji, Hridesh Rajan, Jia Liu, | Summary: Powered by advances in deep learning (DL) techniques, machine learning and artificial intelligence have achieved astonishing successes. However, the rapidly growing needs for DL also led to communication- and resource-intensive distributed training jobs for large-scale DL training, […]

Consistency test of the fine-structure constant from the whole ionization history

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Lu Chen, , , | Summary: In cosmology, the fine-structure constant can affect the whole ionization history. However, the previous works confine themselves to the recombination epoch and give various strong constraints on the fine-structure constant. In this paper, we also take the reionization epoch […]
