The ALMA Frontier Fields
Franz Erik Bauer



The Frontier Fields Legacy Program targets six strong lensing clusters with deep HST and Spitzer imaging to detect and characterize the faint background galaxy population, particularly the first galaxies at z~6-10. We initiated an ALMA survey to produce "shallow" ~2'x2' maps of the Frontier Field cluster fields at 1.1mm to study intrinsically faint dusty star-forming galaxies (DSFGs) and place constraints on the star formation in a variety of interesting extragalactic source populations. Five of the six clusters have now been completed, yielding relatively uniform maps that pinpoint cool dust emission from powerful DSFGs at z > 1. I will present a census of the detected objects thus far, as well as some stacking constraints on the average emission from undetected source populations.
