A Spitzer/IRS study of local luminous infrared galaxies

Abstract:

We present the first results of our program to study a sample of local luminous infrared galaxies (LIRGs, L_IR = 10^11-10^12 L_sun) with the Spitzer infrared spectrograph (IRS). In these proceedings we investigate the behavior of the 9.7 um silicate feature in LIRGs. As opposed to the extreme silicate absorptions observed in ultraluminous infrared galaxies (ULIRGs, L_IR = 10^12-10^13 L_sun), LIRGs exhibit intermediate silicate absorption features, comparable to those of starburst galaxies. We...
