https://zoom.us/j/97377192005?pwd=OUZPR1Z3ZGc5WDZPYW1SakEzV1pvQT09 We are currently in an exciting era of precision cosmology. With the release of the cosmic microwave background data recorded by the Planck satellite, we are now in a position to accurately test the Standard Model of cosmology and particle physics. In this talk, I will present the latest results from a survey to discover and characterize some of the most metal-poor, gas-rich galaxies currently known. These near-pristine environments allow us to study the early phases of dwarf galaxy evolution, probe the chemical signatures of the first stars, and study the primordial abundances of the light elements. I will present some of the key results from this survey. Dr Cooke is hosted by Dr. Diederik Kruijssen (kruijssen@uni-heidelberg.de)
