Description
Galaxy clusters are one of the pillars of future cosmological
observations (DETF), with potentially dramatic statistical power. They
are studied through several wavelengths and methods, including X-ray,
SZ, optical, gamma-ray and weak lensing. A major challenge, but also
potential source of constraining power, is the consistent calibration of
these observables to cluster halo mass. I will present the basics of
cluster theory, and sketch the current state of cluster cosmology.
Thereafter, I focus on the ongoing X-ray XMM Cluster Survey: initial
results, forecast cosmological constraints and how these generalize to
cluster cosmology in general (with an emphasis on systematics in
mass-observable scaling relations).
