Unravelling the deterministic effect of the solid-state diffusion energy barrier for charge carrier on the self-discharge of supercapacitors

Posted by Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Xiaohui Yan, Yue He, Xuncheng Liu, Siqi Jing, Jiajian Guan | Summary: The further development of fast electrochemical devices is hindered by self-discharge. Current strategies for suppressing self-discharge are mainly focused on the extrinsic and general mechanisms including faradaic reactions, charge redistribution, and ohmic leakage. However, the […]

TDCOSMO. XIII. Improved Hubble constant measurement from lensing time delays using spatially resolved stellar kinematics of the lens galaxy

Posted by Chicago

Kavli Affiliate: Joshua A. Frieman | First 5 Authors: Anowar J. Shajib, Pritom Mozumdar, Geoff C. -F. Chen, Tommaso Treu, Michele Cappellari | Summary: Strong-lensing time delays enable measurement of the Hubble constant ($H_{0}$) independently of other traditional methods. The main limitation to the precision of time-delay cosmography is mass-sheet degeneracy (MSD). Some of the […]

Things that might go bump in the night: Assessing structure in the binary black hole mass spectrum

Posted by Chicago

Kavli Affiliate: Daniel E. Holz | First 5 Authors: Amanda M. Farah, Bruce Edelman, Michael Zevin, Maya Fishbach, Jose María Ezquiaga | Summary: Several features in the mass spectrum of merging binary black holes (BBHs) have been identified using data from the Third Gravitational Wave Transient Catalog (GWTC-3). These features are of particular interest as […]

Cosmic Reionization On Computers: Statistics, Physical Properties and Environment of Lyman Limit Systems at $zsim6$

Posted by Chicago

Kavli Affiliate: Nickolay Y. Gnedin | First 5 Authors: Jiawen Fan, Hanjue Zhu, Camille Avestruz, Nickolay Y. Gnedin, | Summary: Lyman Limit Systems (LLSs) are dense hydrogen clouds with high enough HI column densities ($N_{rm HI}$) to absorb Lyman continuum photons emitted from distant quasars. Their high column densities imply an origin in dense environments; […]
