Description

Cosmic Cartography to Counter Cosmic Conundrums. This project aims to make a comprehensive map of cosmic structure spanning four billion light years around our Milky Way, and analyse it to measure how our galactic neighbourhood warps our view of the Universe beyond. Using innovative machine learning methods to combine galaxy positions with galaxy motions this project should reveal hidden structures and determine their impact on our measurements of the expansion rate of the Universe. Expected outcomes include a 3D cosmic map that can be used by astrophysicists in perpetuity; this awe-inspiring new view of our cosmos is expected to provide social and cultural benefits, in addition to economic benefits arising from applying the new statistical methods to big data in industry and government.. Scheme: Discovery Projects. Field: 5101 - Astronomical Sciences. Lead: Prof Tamara Davis
