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 […]
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 […]
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 […]
Kavli Affiliate: Kathleen Cullen & Sridevi Sarma | Authors: Macauley Smith Breault, Pierre Sacré, Zachary B Fitzgerald, John T Gale, Kathleen E Cullen, Jorge A González-Martínez and Sridevi V Sarma | Summary: Abstract A human’s ability to adapt and learn relies on reflecting on past performance. Such reflections form latent factors called internal states that […]
Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Andrew P. Cooper, Sergey E. Koposov, Carlos Allende Prieto, Christopher J. Manser, Namitha Kizhuprakkat | Summary: We describe the Milky Way Survey (MWS) that will be undertaken with the Dark Energy Spectroscopic Instrument (DESI) on the Mayall 4m Telescope at the Kitt Peak National Observatory. Over […]
Kavli Affiliate: Jia Liu | First 5 Authors: Xin Zhang, Minghong Fang, Zhuqing Liu, Haibo Yang, Jia Liu | Summary: Federated learning (FL) has received a surge of interest in recent years thanks to its benefits in data privacy protection, efficient communication, and parallel data processing. Also, with appropriate algorithmic designs, one could achieve the […]
Kavli Affiliate: Jia Liu | First 5 Authors: Zhuqing Liu, Xin Zhang, Jia Liu, , | Summary: To increase the training speed of distributed learning, recent years have witnessed a significant amount of interest in developing both synchronous and asynchronous distributed stochastic variance-reduced optimization methods. However, all existing synchronous and asynchronous distributed training algorithms suffer […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Takuto Ishikawa, Mamoru Matsuo, Takeo Kato, , | Summary: We study temperature dependence of spin Hall magnetoresistance (SMR) in antiferromagnetic insulator (AFI)/metal bilayer systems. We calculate the amplitude of the SMR signal using the quantum Monte Carlo simulation and examine how the SMR depends on the amplitude […]

Kavli Affiliate: Luis C. Ho | First 5 Authors: Suyeon Son, Minjin Kim, Luis C. Ho, Dohyeong Kim, Taehyun Kim | Summary: We report an exceptional mid-infrared flare in the Seyfert 1.8 NGC 3786. In the multi-epoch data from the Wide-field Infrared Survey Explorer, the nuclear mid-infrared brightness of NGC 3786 appears to vary substantially […]
