Population-level Dark Energy Constraints from Strong Gravitational Lensing using Simulation-Based Inference

Posted by dbos Chicago

Kavli Affiliate: Brian Nord | First 5 Authors: Sreevani Jarugula, Brian Nord, Abhijith Gandrakota, Aleksandra Ćiprijanović, | Summary: In this work, we present a scalable approach for inferring the dark energy equation-of-state parameter ($w$) from a population of strong gravitational lens images using Simulation-Based Inference (SBI). Strong gravitational lensing offers crucial insights into cosmology, but […]

Adsorption-controlled Growth of Homoepitaxial c-plane Sapphire Films

Posted by dbos Cornell

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Lena N. Majer, Tolga Acartürk, Peter A. van Aken, Wolfgang Braun, Luca Camuti | Summary: Sapphire is a technologically highly relevant material, but it poses many challenges to performing epitaxial thin-film deposition. We have identified and applied the conditions for adsorption-controlled homoepitaxial growth of c-plane sapphire. […]

Convexification of the Quantum Network Utility Maximisation Problem

Posted by dbos Delft

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Sounak Kar, Stephanie Wehner, , , | Summary: Network Utility Maximisation (NUM) addresses the problem of allocating resources fairly within a network and explores the ways to achieve optimal allocation in real-world networks. Although extensively studied in classical networks, NUM is an emerging area of research in […]
