Title: Steps toward phase space distribution function reconstruction of galaxy dark halos.
Date: 1 May  2011
Place: Cosmology weekly seminars, Physics department, Sharif University

Abstract:
In this talk I will mention some properties of galaxies
dark halo's density profiles and shapes that
we know from gravitational lensing and n-body simulations . then I
will briefly explain the FEM method
and its application to DF reconstruction of spherical stellar
systems and why we can't use
the same steps for non integrable systems. Finally I will introduce
the NAFF method ( Numerical Analysis of Fundamental Frequencies) since
it is one of steps toward the DF reconstruction of non integrable systems.
