    • Destruction of molecular gas reservoirs in early-type galaxies by active galactic nucleus feedback 

      Schawinski, K.; Lintott, C.J.; Kaviraj, S.; Silk, J.; Zuntz, J.; Bayet, E.; Thomas, D.; Maraston, C.; Viti, S.; Sarzi, M.; Yi, S.K.; Joo, S-J.; Daddi, E.; Bell, T. (2009)
      Residual star formation at late times in early-type galaxies and their progenitors must be suppressed in order to explain the population of red, passively evolving systems we see today. Likewise, residual or newly accreted ...

    • Observational evidence for AGN feedback in early-type galaxies 

      Schawinski, K.; Thomas, D.; Sarzi, M.; Maraston, C.; Kaviraj, S.; Silk, J.; Joo, S-J.; Yi, S.K. (2007)
      A major amendment in recent models of hierarchical galaxy formation is the inclusion of so-called active galactic nucleus (AGN) feedback. The energy input from an active central massive black hole is invoked to suppress ...
