SUMMARY:The Physical Characteristics of Faint\, High-redshift Dusty St
 ar-forming Galaxies\, Preliminary Exam\, Stephen McKay\, Physics PhD G
 raduate Student
DESCRIPTION:Once entirely undetected in large galaxy surveys\, dusty s
 tar-forming galaxies (DSFGs)--a population of massive\, dust-enshroude
 d galaxies with prodigious star formation rates (SFRs)--contribute hea
 vily to the cosmic star formation history at high redshifts (z ≳ 1).
  However\, since their original detection nearly three decades ago as 
 submillimeter galaxies (or SMGs)\, a detailed understanding of these g
 alaxies has been extremely difficult to obtain for large samples\, in 
 particular for faint sources that fall below typical wide-field survey
  limits. In this talk\, I will discuss my work on inferring the multiw
 avelength properties of large samples of high-redshift DSFGs using obs
 ervations with the Atacama Large Millimeter/submillimeter Array (ALMA)
  and the James Webb Space Telescope (JWST). I will describe how my wor
 k will shed light on crucial characteristics of the faint DSFG populat
 ion\, including their dust content\, stellar populations\, ongoing sta
 r formation\, molecular gas\, and\, ultimately\, their obscured contri
 bution to the Universe's star formation history across cosmic time.
