[ Computational Astrophysics, Cosmology and CMB ]
Dick Bond works on the theory of tiny cosmic microwave background (CMB) fluctations, geometrical mappings of sound waves when this "oldest light in the Universe" decoupled from matter some 14 gigayears ago. These fluctuations encode information on the many parameters that define cosmic structure formation theory, which he and collaborators determine by analysis of data from Boomerang, CBI and other CMB experiments. The impact this has on inflation and the early universe is of great interest to him, as is the nature and behaviour of dark matter and dark energy. Another area of active research is the "cosmic web" paradigm for structure formation from the nonlinear dynamics of random density fields. He is studying the distribution and state of gas in the Universe that this engenders, through gasdynamical studies of the intergalactic medium at high redshift (Lyman alpha forest) and the intercluster/intracluster medium at lower redshift (the Sunyaev-Zeldovich effect).
