Résumé
| In
these lectures I will
introduce an application of a
weak gravitational lensing
that provides an important
direct link to the study of
the formation and evolution of
galaxies: what are the
(global) properties of the
dark matter halos
as a function of their
baryonic properties. The
lensing signal around
galaxies, i.e. the galaxy-mass
cross-correlation function
can be used for cosmology, but
can also decomposed in the
context of the halo model,
which will also be discussed.
Finally I will review a number
of applications, the latest
results, and what is needed to
make further progress. |
