The role of black hole feedback on galaxy star formation and the degeneracy with halo quenching

Hao Fu, Francesco Shankar, Feng Yuan +9

The interplay between the accretion of supermassive black holes (SMBHs) and the stellar mass growth of the host galaxies is still a matter of hot debate. The accretion of the SMBHs…
