DESCRIPTION:Speakers: Nora Shipp (Massachusetts Institute of Technology)\n
 Recent large photometric\, astrometric\, and spectroscopic surveys have en
 abled the first systematic observations of Milky Way stellar streams in 6D
 . At the same time\, cutting edge cosmological simulations are now at reso
 lutions that allow for the study of dwarf galaxy streams around Milky Way-
 like hosts. In this talk\, I will present the discovery and characterizati
 on of a population of 6D stellar streams with observations from the Dark E
 nergy Survey\, Gaia\, and the Southern Stellar Stream Spectroscopic Survey
  (S5) in comparison to streams identified in cosmological simulations. The
 se comparisons enable deeper studies of satellite populations and tidal di
 sruption in simulations and observations\, and further tests of the small-
 scale challenges to LCDM.\n\nhttps://iaus379.aip.de/event/20/contributions
