Spitzer's Mid-Infrared View on Dusty GalaxyEvolution

摘要

I summarize recent results from spectroscopic Spitzer studies of the evolution of infrared bright galaxies. First, the mid-IR diagnostic toolbox is briefly introduced, with an emphasis on new insights on the calibration of zero points and bolometric corrections of these methods. Then various applications at low and high redshift are summarized, such as the AGN fraction in ULIRGs along a merger sequence, the star formation in QSO hosts, the co-evolution of black hole growth and star formation in Narrow Line Seyfert I galaxies, and the role of AGN at low and high z.
