Poster 128: Logan Kelley – Weighing Abell 2029: How Different Assumptions Change a Galaxy Cluster’s Mass

<< Return to the Virtual URS Main Page

Faculty mentor: Daniel Wik

This project consisted of deriving the value for a galaxy cluster, Abell 2029, multiple times in order to test how the final value for the mass changed when we changed certain assumptions. Assumptions that were tested included: the assumption of hydrostatic equilibrium, the assumption of correctly centered regions, and assuming the equipment you are working with was properly calibrated. This was done to find the assumption which was the biggest source of uncertainty for mass estimation.
