Alexandra Pope (U. Mass Amherst): "TolTEC/LMT Extragalactic Legacy Surveys: A Census of Dust-Obscured Star Formation Over Space and Time"

Millimeter wavelengths are uniquely suited to measure the dust-obscured star formation in galaxies over cosmic time. While simulations predict that a large fraction of the star formation rate density at earlier times is expected to come from galaxies in protoclusters, observations of dust-obscured star formation in protoclusters are limited to a handful of systems. The Large Millimeter Telescope (LMT) can survey large areas of the cosmic web and measure obscured star formation over a range of environments. I will introduce TolTEC; a revolutionary new camera providing a resolution of 5" at 1.1 mm on the LMT. Over the next two years, TolTEC/LMT will conduct two public extragalactic legacy surveys simultaneously at 1.1, 1.4 and 2.1 mm: an Ultra-Deep Survey of star-forming galaxies (~0.5 sq. deg) and a Large Scale Structure survey (~50 sq. deg). I will discuss the science motivation for these surveys and provide details on these rich community datasets. The LSS survey in particular will allow us to probe the relationship between the spatial distribution of dusty star forming galaxies and large scale structure.
