  journal={arXiv: Astrophysics},
The observational link between Supermassive Black Holes (SMBH) and galaxies at low redshift seems to be very tight, and statistically the global evolution of star formation activity and BH accretion activity also seem to trace each other closely. However, pinning down the co-evolution of galaxies and BH on an object-by-object basis remains elusive. I present results from new models for the joint evolution of galaxies, SMBH, and AGN, which may be able to help resolve some of the observational… Expand
