| Abstract: |
We study how IRAC helps to constrain the stellar populations of high redshift galaxies. A rest-frame U-V versus V-J diagram is a powerful diagnostic to distinguish dusty red galaxies from red galaxies with evolved stellar populations. The mass, age and extinction uncertainties are reduced more for red than for blue galaxies when including IRAC. The most massive galaxies at high redshift have red rest-frame U-V colors compared to lower mass galaxies. |
