Measuring the Expansion of the Universe using the Supernova Hubble Diagram
– presented by
Erik Peterson,
5th Year PhD Student at Duke University
Edwin Hubble was one of the first astronomers to provide evidence for the expansion of the Universe simply by comparing a number of astronomical object’s distances to their recessional velocities on what is now known as the ‘Hubble Diagram.’ More recently, Type Ia Supernovae were used to measure the accelerated expansion of the Universe on another Hubble Diagram that reached far deeper into the Universe. That being said, there is plenty more to be learned from the Hubble Diagram, from Type Ia Supernovae, and from our Universe. In this talk, Erik will discuss how much more we can learn from these cosmological tools, specifically diving into his thesis projects, a near-infrared supernova survey called DEHVILS and a peculiar velocity analysis incorporating galaxy groups, as we prepare for NASA’s next flagship mission, The Roman Space Telescope.
