Kavli Affiliate: Paul L. Schechter | First 5 Authors: Chirag Falor, Paul L. Schechter, , , | Summary: The quadruple image configurations of gravitational lenses with vanishing ellipticity are examined. Even though such lenses asymptotically approach circularity, the configurations are stable if the position of the source relative to the vanishing diamond caustic is held […]
Kavli Affiliate: Albert Stebbins | First 5 Authors: Olivier Perdereau, Réza Ansari, Albert Stebbins, Peter T. Timbie, Xuelei Chen | Summary: We present the science case for surveys with the Tianlai dish array interferometer tuned to the $left[ 1300, 1400 right] mathrm{MHz}$ frequency range. Starting from a realistic generation of mock visibility data according to […]
Kavli Affiliate: Ran Wang | First 5 Authors: Yuheng Jia, Sirui Tao, Ran Wang, Yongheng Wang, | Summary: Ensemble clustering integrates a set of base clustering results to generate a stronger one. Existing methods usually rely on a co-association (CA) matrix that measures how many times two samples are grouped into the same cluster according […]
Kavli Affiliate: Jia Liu | First 5 Authors: Haibo Yang, Peiwen Qiu, Jia Liu, Aylin Yener, | Summary: This paper considers over-the-air federated learning (OTA-FL). OTA-FL exploits the superposition property of the wireless medium, and performs model aggregation over the air for free. Thus, it can greatly reduce the communication cost incurred in communicating model […]
Kavli Affiliate: John Richardson | First 5 Authors: Nicholas Waytowich, James Hare, Vinicius G. Goecks, Mark Mittrick, John Richardson | Summary: Traditionally, learning from human demonstrations via direct behavior cloning can lead to high-performance policies given that the algorithm has access to large amounts of high-quality data covering the most likely scenarios to be encountered […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Aklant Kumar Bhowmick, Laura Blecha, Yueying Ni, Tiziana Di Matteo, Paul Torrey | Summary: We explore implications of a range of black hole (BH) seeding prescriptions on the formation of the brightest $zgtrsim6$ quasars in cosmological hydrodynamic simulations. The underlying galaxy formation model is the same as […]
Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Joseph E. Rodriguez, Samuel N. Quinn, Andrew Vanderburg, George Zhou, Jason D. Eastman | Summary: We present the discovery and characterization of six short-period, transiting giant planets from NASA’s Transiting Exoplanet Survey Satellite (TESS) — TOI-1811 (TIC 376524552), TOI-2025 (TIC 394050135), TOI-2145 (TIC 88992642), TOI-2152 (TIC 395393265), […]

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Paolo Campeti, Eiichiro Komatsu, , , | Summary: We derive a new upper bound on the tensor-to-scalar ratio parameter $r$ using the frequentist profile likelihood method. We vary all the relevant cosmological parameters of the $Lambda$CDM model, as well as the nuisance parameters. Unlike the Bayesian analysis […]
