Our focus:
  Gravitational Lensing

Welcome to the web site of the lensing research group of Ben Metcalf at the Department of Physics and Astronomy - University of Bologna. Here you will find all information about our research projects in theoretical astrophysics and cosmology!

Lensing helps to find a solution to many different puzzles in astronomy. Today we are able to unveil the distribution of Dark Matter in Lensing Galaxies? This gives important clues on one of the central questions of structure formation: the role played by Dark Matter.

Tuesday's Talk: Since dark matter was postulated by Fritz Zwicky in 1934 much effort has been put into unveiling what is thought to constitute 23% of the energy density of the universe. However, direct evidence of its existence and a concrete understanding of its nature have remained elusive. Studies on the distribution of dark matter by means of their gravitational interaction are nevertheless feasible and provide important clues on structure formation. This is where the combination of stellar population synthesis and free-form lens modelling comes in helpful.
