Posted by dbos Peking

Kavli Affiliate: Huawei Zhang | First 5 Authors: Jonathan Cabrera Garcia, Timothy C. Beers, Yang Huang, Xin-Yi Li, Gaochao Liu | Summary: We employ a sample of 135,873 RR Lyrae stars (RRLs) with precise photometric-metallicity and distance estimates from the newly calibrated $P$–$phi_{31}$–$R_{21}$–[Fe/H] and $Gaia$ $G$-band $P$–$R_{21}$–[Fe/H] absolute magnitude-metallicity relations of Li et al., combined […]

Six-Point AdS Gluon Amplitudes from Flat Space and Factorization

Posted by dbos UCAS

Kavli Affiliate: Xinan Zhou | First 5 Authors: Luis F. Alday, Vasco Gonçalves, Maria Nocchi, Xinan Zhou, | Summary: We present a powerful new approach to compute tree-level higher-point holographic correlators. Our method only exploits the flat-space limit, where we point out a novel and important simplification, and factorization of amplitudes in AdS. In particular, […]

The UV Continuum Slopes of Early Star-Forming Galaxies in JADES

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Michael W. Topping, Daniel P. Stark, Ryan Endsley, Lily Whitler, Kevin Hainline | Summary: The power-law slope of the rest-UV continuum ($f_{lambda}proptolambda^{beta}$) is a key metric of early star forming galaxies, providing one of our only windows into the stellar populations and physical conditions of $z>10$ galaxies. […]

Biexcitons are bound in CsPbBr3 Perovskite Nanocrystals

Posted by klaurent Berkeley

Kavli Affiliate: David T. Limmer | First 5 Authors: Yoonjae Park, David T. Limmer, , , | Summary: We study the energetics of quasi-particle excitations in CsPbBr3 perovskite nanocrystals using path integral molecular dynamics simulations. Employing detailed molecular models, we elucidate the interplay of anharmonic lattice degrees of freedom, dielectric confinement, and electronic correlation on […]

Spatio-Temporal Calibration for Omni-Directional Vehicle-Mounted Event Cameras

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Xiao Li, Yi Zhou, Ruibin Guo, Xin Peng, Zongtan Zhou | Summary: We present a solution to the problem of spatio-temporal calibration for event cameras mounted on an onmi-directional vehicle. Different from traditional methods that typically determine the camera’s pose with respect to the vehicle’s body frame […]
