Big Data, Big Skies: The Era of the Nancy Grace Roman Telescope – Jen Sobeck (Caltech, USA)

Abstract: The Nancy Grace Roman Space Telescope, the next NASA flagship mission set to launch by May 2027, will revolutionize our understanding of the cosmos.  With a field of view 100 times greater than the Hubble Space Telescope at comparable resolution, Roman will perform an unprecedented high-latitude survey to map the distribution of dark matter and measure the expansion history of the universe through weak lensing and galaxy clustering.  Simultaneously, the Roman microlensing survey will conduct a census of exoplanets in the Milky Way Bulge, identifying worlds ranging from the habitable zone to free floating planets. Roman will generate a staggering 1.4 terabytes of data every day, sending down roughly 20 petabytes over its baseline five-year mission—a data volume that dwarfs previous space observatories.  This presentation will provide an overview of the Roman mission as well as discuss in detail one of its core component surveys, the Galactic Bulge Time Domain Survey.
