Scientific paper

Spitzer is uniquely able to provide the data we need to make an unbiased estimate of the total amount of current star formation in galaxies in protoclusters. Such information is crucial to understanding the relative formation timescales of the stellar populations, their galaxies, and even the intracluster medium of the host protoclusters. We propose to obtain deep MIPS 24 micron observations of the protocluster MRC 1138-262 at z=2.1. The rest frame wavelengths sampled by the MIPS bandpass will contain the strong PAH feature at 7.7 microns, so the data will be sensitive to current star formation. The proposed depth would detect an L^* luminous IR galaxy with L(IR) = 10^{11} L_sun at the 5 sigma level.
