SUMMARY:Revealing Obscured Dusty Star-Forming Galaxies in the Early Un
 iverse\, Astronomy Colloquium\, Dr. Sinclaire Manning\, Univ. Massachu
 setts -  Amherst
DESCRIPTION:Since the late 1990s\, infrared (IR) and submillimeter (su
 bmm) extragalactic surveys have revealed a significant population of e
 xtreme star-forming galaxies (forming upwards of 1000 solar masses per
  year) shining intensely as dust-reprocessed ultraviolet and optical l
 ight from newly formed stars emits in this regime. These early works d
 rastically altered our understanding of the prevalence of dusty star-f
 orming galaxies (DSFGs) beyond our local Universe and guided a new era
  of astronomical discovery. In this talk\, I will provide a brief hist
 ory of far-IR/submm observations of DSFGs before discussing the advanc
 ements made at even longer (millimeter) wavelengths\, in particular wi
 th the Atacama Large Millimeter Array (ALMA). I will then introduce th
 e Mapping Obscuration to Reionization with ALMA (MORA) survey\, which 
 aims to efficiently detect redshift > 3 DSFGs at 2 millimeters and my 
 work to characterize a sub-sample of the DSFG population\, called OIR-
 dark\, which have eluded detection until the last few years due to a c
 ombination of their extreme dust obscuration and lower star-formation 
 rates. Finally\, I will look ahead to future surveys with ALMA\, LMT\,
  and JWST as we work to take census and determine the physical propert
 ies of the earliest known dust-obscured galaxies residing in the first
  billion years of the Universe.
