Abstract
Galaxy cluster surveys have been recognized as one of the most powerful probes of dark energy, but their constraining power is limited by the accuracy of mass calibration. I will present my research on using simulations to improve mass calibration methods, including galaxy dynamics, weak gravitational lensing, clustering, and X-ray observations. These results not only mitigate the systematic uncertainties in current cluster surveys but also help the optimization for future ground- and space-based missions.
