One-loop thermal radiation exchange in gravitational wave power spectrum

Kavli Affiliate: Misao Sasaki | First 5 Authors: Atsuhisa Ota, Misao Sasaki, Yi Wang, , | Summary: The radiation-dominated universe is a key ingredient of the standard Big Bang cosmology. Radiation comprises numerous quantum elementary particles, and the macroscopic behavior of radiation is described by taking the quantum thermal average of its constituents. While the […]

Impact of Property Covariance on Cluster Weak lensing Scaling Relations

Kavli Affiliate: Joshua Frieman | First 5 Authors: Zhuowen Zhang, Arya Farahi, Daisuke Nagai, Erwin T. Lau, Joshua Frieman | Summary: We present an investigation into a hitherto unexplored systematic that affects the accuracy of galaxy cluster mass estimates with weak gravitational lensing. Specifically, we study the covariance between the weak lensing signal, $DeltaSigma$, and […]

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

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

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 […]
