HIFlow: Generating Diverse HI Maps and Inferring Cosmology while Marginalizing over Astrophysics using Normalizing Flows

Posted by klaurent Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: Sultan Hassan, Francisco Villaescusa-Navarro, Benjamin Wandelt, David N. Spergel, Daniel Anglés-Alcázar | Summary: A wealth of cosmological and astrophysical information is expected from many ongoing and upcoming large-scale surveys. It is crucial to prepare for these surveys now and develop tools that can efficiently extract most […]

Relative Entropy Gradient Sampler for Unnormalized Distributions

Posted by klaurent Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Xingdong Feng, Yuan Gao, Jian Huang, Yuling Jiao, Xu Liu | Summary: We propose a relative entropy gradient sampler (REGS) for sampling from unnormalized distributions. REGS is a particle method that seeks a sequence of simple nonlinear transforms iteratively pushing the initial samples from a reference distribution […]

Oxide two-dimensional electron gas with high mobility at room-temperature

Posted by klaurent Cornell

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Kitae Eom, Hanjong Paik, Jinsol Seo, Neil Campbell, Evgeny Y. Tsymbal | Summary: The prospect of 2-dimensional electron gases (2DEGs) possessing high mobility at room temperature in wide-bandgap perovskite stannates is enticing for oxide electronics, particularly to realize transparent and high-electron mobility transistors. Nonetheless only a […]

Sparse metapiles for shear wave attenuation in half-spaces

Posted by Caltech

Kavli Affiliate: Chiara Daraio | First 5 Authors: Paolo Celli, Ilaria Nunzi, Andrea Calabrese, Stefano Lenci, Chiara Daraio | Summary: We show that shear waves traveling towards the surface of a half-space medium can be attenuated via buried one-dimensional arrays of resonators — here called metapiles — arranged according to sparse patterns around a site […]
