Abstract
We report the first investigation of cool-core properties of galaxy clusters selected via their Sunyaev-Zel_s14dovich (SZ) effect. We use 13 galaxy clusters uniformly selected from 178 deg2 observed with the South Pole Telescope (SPT) and followed up by the Chandra X-ray Observatory. They form an approximately mass-limited sample (>3 × 1014 M _s13_s178857_s19 h -1 70) spanning redshifts 0.3 < z < 1.1. Using previously published X-ray-selected cluster samples, we compare two proxies of cool-core strength: surface brightness concentration (c SB) and cuspiness (_s13_s17945_s19).
