I will present early results from the GOODS study of the Hubble Deep Field North with Spitzer/IRAC. The IRAC data span wavelengths from 3--8 micron, and observe the rest--frame near--infrared emission from galaxies at z ˜ 0.5-5. The IRAC data coupled with deep, ground--based and HST data probe the galaxy spectral--energy distributions from rest--frame UV to near--infrared wavelengths, and provide a full panchromatic view of the stellar emission from distant galaxies. I will discuss the constraints on the total stellar masses of galaxies using this dataset, and I will present implications for the evolution of the global stellar--mass density of galaxies at z ˜ 0.5-5.
This work is based in part on observations made with the Spitzer Space Telescope, which is operated by JPL/Caltech under NASA contract 1407, and in part on observations made with the NASA/ESA Hubble Space Telescope, which is operated by AURA under NASA contract NAS5-26555. Support for this work, part of the Spitzer Space Telescope Legacy Science Program, was provided by NASA through contract 1224666, and also through contract 9607785, issued by JPL/Caltech.
