Cosmology Seminar
Cosmology Seminars are held at on Mondays at 11 am during the academic year, on the 3rd floor Varian conference room. These are more focused and less didactic than the colloquium, and provide a stage for younger researchers to present their work in more detail.
Please contact Risa Wechsler, Daniel Gruen, Josh Meyers, or Kyle Story for more information.

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

The statistical properties of the primordial curvature perturbations are a key ingredient of the success of the LCDM model in explaining the Universe as we observe it today.
