Constraining Feeble Neutrino Interactions with Ultralight Dark Matter
Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Abhish Dev, Gordan Krnjaic, Pedro Machado, Harikrishnan Ramani, | Summary: If ultralight $(ll$ eV), bosonic dark matter couples to right handed neutrinos, active neutrino masses and mixing angles depend on the ambient dark matter density. When the neutrino Majorana mass, induced by the dark matter background, is […]

Can Carbon Fractionation Provide Evidence for Aerial Biospheres in the Atmospheres of Temperate Sub-Neptunes?
Kavli Affiliate: Sara Seager | First 5 Authors: Ana Glidden, Sara Seager, Jingcheng Huang, Janusz J. Petkowski, Sukrit Ranjan | Summary: The search for signs of life on other worlds has largely focused on terrestrial planets. Recent work, however, argues that life could exist in the atmospheres of temperate sub-Neptunes. Here, we evaluate the usefulness […]

Black Holes Decohere Quantum Superpositions
Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Gautam Satishchandran, Robert M. Wald, , | Summary: We show that if a massive body is put in a quantum superposition of spatially separated states, the mere presence of a black hole in the vicinity of the body will eventually destroy the coherence […]

The Quadruple Image Configurations of Asymptotically Circular Gravitational Lenses
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 […]

The Tianlai dish array low-z surveys forecasts
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 […]

Ensemble Clustering via Co-association Matrix Self-enhancement
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 […]

Over-the-Air Federated Learning with Joint Adaptive Computation and Power Control
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 […]

Learning to Guide Multiple Heterogeneous Actors from a Single Human Demonstration via Automatic Curriculum Learning in StarCraft II
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 […]

Probing the $zgtrsim6$ quasars in a universe with IllustrisTNG physics: Impact of gas-based black hole seeding models
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 […]
