| In the past 5 years the Spitzer Space Observatory has provided a tremendous amount of new information in the area of galaxy formation and evolution. This talk will highlight some recent Spitzer results in this field and what can be learned from them about black hole growth, co-evolution of/feed-back between black hole and starbursts, and the quantification of star formation and AGN activity in dusty galaxies. I will also present some of the very first related results from the Science Demonstration Phase of the Herschel Space Observatory. |
