Desai et al. (2007)

Desai et al. (2007). Large variation in MIR spectra driven by PAH, H 2 O ice, hydrocarbon & silicate absorption 30-40% of the power of a typical ULIRG comes from an AGN. This rises with luminosity, dust temp, merger stage, etc.

Observations of Molecular Outflows in Quasars

Observations of Molecular Outflows in Quasars. Anna Boehle March 2 nd , 2012. Background. merger driven galaxy evolution: gas rich mergers -> starbursts and AGN activity star-formation is quenched as gas is expelled transition from blue to red what drives this negative feedback?
