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

Posted by dbos August 30, 2023Peking

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 […]
