The structure and principles of the universe

How does the universe work?

We are at the forefront of understanding the formation and evolution of stars and galaxies and explore the underlying sub-atomic building blocks of our Universe from the Higgs Boson to gravitational waves. Our research drives new technologies in space imaging, robotics and semiconductors for aerospace, nuclear waste management and healthcare.

To understand what 'is', you need to understand what 'could be'. We are developing statistical methods to quantitate risk in complex systems and determining how space and numbers can be assembled, either continuously or algebraically, whilst mapping the effects of symmetries.

We have a total of £17 million in grant income in this area. Our researchers play a leading part in the largest multi-institution international collaborations and in consortia using the most modern telescope facilities.

Revolutionary HiPERCAM captures movies of space

Professor Vik Dhillon is the lead scientist behind HiPERCAM, which can take more than 1,000 images per second and will revolutionise scientists' understanding of stars and black holes. The camera is mounted on the world's largest optical telescope, the Gran Telescopio Canarias.

LIGO: Gravitational waves detected 100 years after Einstein's prediction




Dr Ed Daw was part of the LIGO collaboration that observed ripples in the fabric of spacetime, known as gravitational waves, for the first time.

Axions and WIMPS: Particle physicists debate dark matter

To date there has been no conclusive proof of the existence of dark matter. In this podcast, Professor Dan Tovey and Dr Ed Daw debate two theories that may explain it – axions and weakly interacting massive particles (WIMPs).

Sheffield telescope facilities

There are two telescopes on the roof of the Hicks Building: a robotic 0.25m telescope and a computer-controlled 0.40m telescope, which our students use during their astrophysics courses. We also share a 0.5m telescope with the University of Durham at the William Herschel Observatory on La Palma.

Our astrophysics researchers have uploaded images they've captured using our telescopes to their Flickr site, plus snaps from our undergraduate field trips to La Palma.
