Résumé
| I
will review the cosmological and
astrophysical motivations for
measuring the mass and internal
structure of galaxy clusters,
including probing dark energy, the
nature of dark matter, and the
environment of galaxies
within/surrounding clusters.
I will also present the
theoretical, observational, and
modeling details of several
lensing-based measurement
techniques, including the "simple"
mass enclosed within the Einstein
radius, parametric modeling
techniques, and "non-parametric"
methods. From the early days
of lensing-based cluster studies,
lensing mass measurements have
been compared with results from
other techniques, at times
creating great controversy.
I will review these
comparisons, and discuss the
growing trend towards joint
analysis of lensing, X-ray, and
dynamical data. The lectures
will close with a summary of major
unsolved problems and future
opportunities. |
