Programme on Computational Cosmology

What are we doing?

We address how data from enormous experiments can be processed, and look at ways of extending to other disciplines methods that are developing in astrophysics and cosmology

Why is it important?

For most of scientific history, how fast we added to our knowledge of the universe was limited by the amount of data available. 21st century science is fundamentally different. Advances in technology provide an unprecedented wealth of information to researchers in diverse fields across the sciences

How are we different?

We are a team of astrophysicists who recognise the tools and technologies we are developing to map the skies can be used in many other fields of analysis. Our focus is on enhancing collaboration across disciplines and sharing methodologies that will accelerate progress in fields as diverse as oceanography, climate science and medicine.

Projects

Processing Data: we are working on methods required for processing and using data from multi-detector experiments that collect data on long time scales.

Applying tools from modelling the universe: we are developing and using codes that make it possible to model the evolution of a significant piece of the early Universe and still zoom in on the formation of an individual galaxy like the Milky Way. Our experience has allowed us to undertake the largest, detailed, gravitational/hydro-dynamical simulation of the visible Universe.

Citizen Science: our Zooniverse project has pioneered a novel approach to ensure that in processing data, the ability to make serendipitous discoveies and unexpected connections is not lost. It began with Galazy Zoo, where 250,000 volunteers were recruited to analyse data from the Sloan Digial Sky Survey, of one million galaxies, producing classifications more accurate than current state-of-the-art computer models. The volunteers made change chance discoveries of new types of objects like the super-star-forming Pea Galaxies and the unusual Hanny’s Voorwerp. The Zooniverse platform has now expanded fields like climate sciencie, papyrology and zoology and now has more than one million volunteers.
