[3.05] Calibrating the Mass-Temperature Relationship of Galaxy
Clusters  N. A. Bond, N. Bahcall, A. Sette (Princeton
University)  We present the most recent calibration of the mass-
temperature relationship for galaxy clusters. Using separate
data from weak gravitational lensing and X-ray observations, we
can empirically determine the relationship without assuming
hydrostatic equilibrium or resorting to any virial arguments. We
will analyze the primary sources of error in the mass
measurements (including the mass-sheet degeneracy, contamination
due to large-scale structure, and the accuracy of the NFW and
isothermal mass profile fits) and consider how they might affect
the relationship.  [Previous] | [Session 3] | [Next]  Bulletin
