1 University of Durham Institute for Computational Cosmology Astronomy Research at Durham

2 Astronomy at Durham

3 ~90 astronomers in 5 groups: Xgal theory & observations (45) Astronomical instrumentation (32) Gamma rays (9) High energy astro (3) Historical astronomy (1) Astronomy at Durham

4 University of Durham Institute for Computational Cosmology The Institute for Computational Cosmology Funded by: JIF JREI Prof Peter Ogden Durham University  New building  Ogden Chair  New lectureship  COSMA-1 Supercomputer The “Cosmology machine” The Ogden Centre for Fundamental Physics Opened by Tony Blair on Oct/02

5 University of Durham Institute for Computational Cosmology Key questions addressed at Durham 1.What is the universe made of? 2.What is the identity of the dark matter? 3.What are the values of the fundamental cosmological parameters? 4.What is the origin of cosmic structure? 5.How do galaxies form and evolve? 6.What is role of quasars in galaxy formation? 7.Astrophysics of extreme objects (black holes, gamma ray sources)

6 University of Durham Institute for Computational Cosmology Research tools 1.Observations (space and ground-based telescopes) – Whole wavelength range from  -rays to radio – 4% of all worldwide telescope time (ESO VLT, Gemini) – Large surveys of galaxies and quasars – Targetted observations 2. Theory –Large supercomputer simulations –Analytical techniques (semi-analytic galaxy formation) –Modelling
