  1. Bernard60: Conference Summary Peter Coles (University of Nottingham)

  2. The abnormal distribution

  3. Why is the density field so lognormal?

  4. “CONCORDANCE”

  5. The Standard Model

  6. Cosmic Comments • The consistency of so many different measurements with a “standard” model is truly remarkable • ..but the standard model is not complete • Can it be completed? • Landscape versus Prediction • Is there a fundamental theory? • Anthropic principles

  7. Universe versus University • Cold Dark Matter = administration • Baryons = academics • Remorseless growth of CDM does not imply the same for baryons (“downsizing”) • “Chaos”= “a space where no information exists or where information is lost.” • Dark Energy=government interference

  8. “All science is cosmology” Arthur Stanley Eddington

  9. Galaxies and Surveys • Galactic archaeology • Is the Milky Way a freak? • “The only normal person there was Bernard…” • Dwarf galaxies: are they segregated? • SDSS versus 2dFGRS

  10. GAIA: One Billion Stars in 3-d will Provide… • in our Galaxy… • the distance and velocity distributions of all stellar populations • the spatial and dynamic structure of the disk and halo • its formation history • …and beyond • definitive distance standards out to the LMC/SMC • rapid reaction alerts for supernovae and burst sources (~20,000) • QSO detection, redshifts, microlensing structure (~500,000) • fundamental quantities to unprecedented accuracy:  to 10-7 (10-3 present)

  11. “The Essence of Cosmology is Statistics” George McVittie

  12. SKA (Square Kilometre Array) • 0.15-20 GHz • 1 sq. deg. (1.4 GHz) • interferometer • 0.1 arcsecond resolution at 1.4 GHz (like Hubble) • Best ever sensitivity in radio!

  13. Precision Cosmology “…as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns -- the ones we don't know we don't know.”

  14. WMAP • WMAP has raised the bar for quantitative cosmological studies.. • There are anomalies, such as the “Axle of Elvis” • Polarization is hard… • Sunyaev-Zel’dovich.

  15. “If tortured sufficiently, data will confess to almost anything” Fred Menger

  16. Polarization Map (?)

  17. Gravitational Waves • Experiments: nearly there after decades of steady progress! • Theory: progress only in last few years.. • Holy Grail • The Grail Quest was a futile search for an non-existent object of dubious significance which consumed a vast amount of resources.

  18. Happy Birthday Bernard! ..and thanks!!
