Observing Dark Energy

Scheme: Wolfson Research Merit Awards

Organisation: University College London

Dates: Apr 2008-Mar 2013

Value: £100,000

Summary: One of the greatest mysteries in the whole of science is the prospect that 75% of the Universe is made from a mysterious substance known as ‘Dark Energy’. Since a further 21% of the Universe is made from invisible ‘Cold Dark Matter’ that can only be detected through its gravitational effects, the ordinary atomic matter making up the rest is apparently only 4% of the total cosmic budget. These discoveries require a shift in our perception as great as that made after Copernicus’s revelation that the Earth moves around the Sun. My research aims to quantify Dark Energy, alternatives to Dark Energy, and the properties of elementary particles called neutrinos. I play leadership roles in several international surveys,in particular the Dark Energy Survey (DES), which will start observing in late 2012 and the Hubble SpaceTelescope Multi-Cycle Treasury CLASH programme, which started in 2010. This research will lead to either establishing the Dark Energy and Dark Matter paradigms, or to an entirely new paradigm, and potentially to detection of the neutrino mass.
