Research Expertise and Interest
astrophysics, black hole, dark matter, cosmology, formation and evolution of galaxies, cosmic microwave background radiation
Understanding the formation and evolution of galaxies and large scale structure in the Universe has been the central theme of my recent research. With the aid of large supercomputers, my collaborators and I have performed numerical simulations of the clustering of dark matter in various cosmological models of structure formation from the Early Universe until the present day. By comparing the simulation results with astronomical observations, constraints can be obtained on the nature of dark matter such as the mass of neutrinos and on cosmological parameters such as the density and expansion rate of the Universe. Another part of my research effort has been on the computation of the temperature variations imprinted on the cosmic microwave background radiation which provides a snapshot of the infant Universe. Other interests include theoretical particle physics and classical violin performance.
