Constraints on Non-Thermal Pressure at galaxy cluster outskirts from a Joint SPT and XMM-Newton Analysis

Arnab Sarkar, Michael McDonald, Lindsey Bleem +11

We present joint South Pole Telescope (SPT) and XMM-Newton observations of 8 massive galaxy clusters (0.8--1.7$\times$10${}^{15}$ M${}_{\odot }$) spanning a redshift range of 0.16 to 0.…
