Cold Gas in Massive Galaxies as A Critical Test of Black Hole Feedback Models
Jingjing Shi, Yingjie Peng, Benedikt Diemer +15
Black hole feedback has been widely implemented as the key recipe to quench star formation in massive galaxies in modern semi-analytic models and hydrodynamical simulations. As the…
On the formation of massive quiescent galaxies with diverse morphologies in the TNG50 simulation
Minjung Park, Sandro Tacchella, Erica J. Nelson +7
Observations have shown that the star-formation activity and the morphology of galaxies are closely related, but the underlying physical connection is not well understood. Using th…
