Cross-Calibration of Cluster Mass-Observables

Understand

This paper is a first step towards developing a formalism to optimally extract dark energy information from number counts using multiple cluster observation techniques.

• We use a Fisher matrix analysis to study the improvements in the joint dark energy and cluster mass-observables constraints resulting from combining cluster counts and clustering abundances measured with different techniques.
• We use our formalism to forecast the constraints in Omega_{DE} and w from combining optical and SZ cluster counting on a 4000 sq.
• degree patch of sky.
