Galaxy archaeology in the nearby Universe: unearthing artifacts of galaxy formation in our own backyard
Speaker: Alan McConnachie of the DAO
While there may be 400 billion or so galaxies in the Universe, there are only a handful that are close enough so that astronomers can study their individual stars. In this talk, I will discuss how precision observations of individual stars in our own Milky Way galaxy and our nearest large neighbor, Andromeda, are helping to shed light on important questions in cosmology and transform our understanding of what a galaxy actually is. How and when did galaxies form? How big are galaxies really? What and where is dark matter? And what is the ultimate fate for the Milky Way?
