An infrared view of AGN feedback: ionized, coronal and molecular phases.

The infrared spectrum of type-2 quasars is practically unexplored even though it permits to trace outflows in the 
molecular, ionized and coronal phases simultaneously. Different modes of AGN feedback are considered to be key 
processes influencing the evolution of galaxies by regulating black hole and galaxy growth. However, observational 
confirmation of a dramatic impact of AGN feedback in large galaxy samples is still missing. Is AGN feedback the Rosetta 
stone of galaxy evolution or is it time to consider other galaxy processes capable of halting galaxy growth? I will present 
preliminary results of a new project aimed to provide the first characterization of quasar-induced outflows in three gas 
phases (ionized, coronal and molecular) in a sample of nearby type-2 quasars and study their impact in the young stellar 
populations, on-going star formation and molecular gas reservoirs of the galaxies.
