"A deep ALMA image of the Hubble Ultra Deep Field"

I will present new results from the first deep ALMA continuum image of the Hubble Ultra Deep Field (HUDF), designed to better connect our UV/optical and FIR/mm views of the high-redshift Universe. From a mosaic of 45 ALMA pointings we have constructed a 1.3mm image covering the full 4.5 sq arcmin of the HUDF as previous imaged with WFC3/IR and ACS on Hubble. This new image reaches an rms depth of 35 micro-Jy at a resolution of of 0.7 arcsec. I will describe the design and implementation of this project, and the analysis of the final data product both for source discovery and stacking in the galaxy mass/redshift plane. After presenting our results I will discuss the implications of our findings for our understanding of the 1.3mm background, the mass dependence of star formation and dust obscuration, and the history of cosmic star-formation density. I will close by discussing the prospects for future progress.
