Talk title: “From pixels to cosmology — how we make sense of the sky”

Abstract: Over the past two decades, we used observational data from the sky to construct a cohesive story about the the universe’s formation and contents. In this talk, I will describe how we analyze hundreds of thousands of pixelated images to derive the current cosmological models. I will highlight the key role that modern galaxy surveys play in the process and the next pressing questions we are faced with.
