Understanding Shape and Centroid Deviations in 39 Strong Lensing Galaxy Clusters in Various Dynamical States

Posted by dbos MIT

Kavli Affiliate: Michael McDonald | First 5 Authors: Raven Gassis, Matthew B. Bayliss, Keren Sharon, Guillaume Mahler, Michael D. Gladders | Summary: Through observational tests of strong lensing galaxy clusters, we can test simulation derived structure predictions that follow from $Lambda$ Cold Dark Matter ($Lambda$CDM) cosmology. The shape and centroid deviations between the total matter […]

Brochosome-inspired binary metastructures for pixel-by-pixel thermal signature control

Posted by dbos Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Zhuo Li, Lin Wang, Xiu Liu, Jiayu Li, Hyeong Seok Yun | Summary: In nature, nano/micro-structured materials are adopted by various species to generate colors or achieve camouflage. Here, inspired by leafhopper-generated brochosomes, we design binary metastructures composed of pixel twins to achieve pixelated thermal signature control […]

The role of turbulence in high-mass star formation: Subsonic and transonic turbulence are ubiquitously found at early stages

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Chao Wang, Ke Wang, Feng-Wei Xu, Patricio Sanhueza, Hauyu Baobab Liu | Summary: Context. Traditionally, supersonic turbulence is considered to be one of the most likely mechanisms to slow down the gravitational collapse in dense clumps, thereby enabling the formation of massive stars. However, several recent studies […]

Masked Space-Time Hash Encoding for Efficient Dynamic Scene Reconstruction

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Zilong Chen, Guokang Wang, Yafei Song, Huaping Liu | Summary: In this paper, we propose the Masked Space-Time Hash encoding (MSTH), a novel method for efficiently reconstructing dynamic 3D scenes from multi-view or monocular videos. Based on the observation that dynamic scenes often contain substantial […]
