The formation of structure and galaxies throughout the
Universe is the driving force behind billion-dollar Technological
developments such as the Square Kilometer Array, the James Webb Space
Telescope, and Extremely Large (ground-based)
Telescopes. I will take the audience through a tour of the
formation and evolution of the largest structures in the Universe,
highlighting the inter-dependency upon physics and micro-physics across
a wide dynamic range. While I will discuss the success of the
current astrophysical paradigm in which this work is conducted, the
emphasis of the talk will be on several of the key unanswered scientific
questions driving the UK's participation in these (and several other)
big international projects. Recent highlights to be touched upon
will include: simulating the first objects in the universe, the
near-field cosmological structure of the Milky Way, and alternative
theories of gravity.
BRAD GIBSON. B.Sc. (Waterloo, 1988), Ph.D.
(British Columbia, 1995),
Professor of Theoretical Astrophysics (University of Central Lancashire,
UK, 2006-); Professor of Astrophysics (Swinburne University, Australia,
2000-2005); Research Associate (University of Colorado, 1998-2000),
Fellow (Australian National University, 1995-1998).
Scientific interests: galaxy formation and evolution (designing
high-performance computational tools to simulate galaxy formation), the
distance scale (determined the expansion rate of the Universe as part of
the Hubble Space Telescope Key Project on the Extragalactic Distance
Scale), chemical evolution of the intergalactic and interstellar medium,
high-velocity clouds (uncovered the mystery of the anomalous velocity
clouds circling the Milky Way), galactic archaeology (employing forensic
techniques to deconstruct the history of the Milky Way - see April 2007
issue of Scientific American for his article on the subject), stellar
populations, high performance computational astrophysics, astrophysical
sociology, novel instrumentation (built the world's first Liquid Mirror
Telecope Observatory - a 2.7-metre facility outside of Vancouver -
awarded a SPIE Scholarship in Optical Engineering for this work).
