| Abstract: | The early chemical evolution of the Galaxy and the Universe is vital to our understanding of a host of astrophysical phenomena. Since the oldest, most metal-poor stars are relics from the high-redshift universe, they probe the chemical and dynamical conditions of a time when large galaxies first began to assemble. With the new SkyMapper telescope, we have been searching for additional metal-poor stars with great success. I will report on these ongoing efforts and our discovery of a new star with a record low abundance of [Fe/H] < -7.0. |
