Title: Structure formation and Spherical Collapse Model in dark energy
models
Date: Tuesday, April 27th, 2010
Time: 12:00
Venue: Villa Bazzoni

Abstract:
Despite efforts from both observational and theoretical sides,
the nature of the dark energy remains obscure. Consequently, a plethora
of different models has been proposed for the origin and the time
evolution of the dark energy. Despite the fact that observations
constrain the present value of w quite tightly, the time evolution of
the equation-of-state parameter is rather poorly constrained. I will
present results on structure formation for different class of dark
energy models, with and without dark energy clumps. I also shortly
review the numerical techniques necessary for the spherical collapse
approach.
