On the dominant role of wind in the quasar feedback mode in the late stage evolution of massive elliptical galaxies

Posted by dbos Peking

Kavli Affiliate: Yingjie Peng | First 5 Authors: , , , , | Summary: In this paper we investigate the role of AGN feedback on the late stage evolution of elliptical galaxies by performing high-resolution hydrodynamical simulation in the {it MACER} framework. By comparing models that take into account different feedback mechanisms, namely AGN and […]

Determining Quasi-Equilibrium Electron and Hole Distributions of Plasmonic Photocatalysts using Photomodulated X-ray Absorption Spectroscopy

Posted by dbos Caltech

Kavli Affiliate: Scott K. Cushing | First 5 Authors: Levi D. Palmer, Wonseok Lee, Chung Li Dong, Ru-Shi Liu, Nianqiang Wu | Summary: Most photocatalytic and photovoltaic devices operate under broadband, constant illumination. Electron and hole dynamics in these devices, however, are usually measured using ultrafast pulsed lasers in a narrow wavelength range. In this […]
