Multiwavelegth view of XLSSC 122. Top: dirty map of the joint ALMA+ACA Band 3 observations overlaid with the distribution of member galaxies of the cluster shown as small gold circles, as in all other panels. The black contours are drawn at [−4.5, −3.5, −2.5, −1.5, 1.5, 2.5, 3.5]-σ. Middle: XMM-Newton image of Mantz et al. (2018) overlaid with the directly visible SZ decrement as seen by the ALMA+ACA imaging with a uv-taper of 10 kλ. Bottom: HST imaging from Willis et al. (2020) used to find the cluster members. Here, we overlay in black the directly visible SZ decrement as seen by the ALMA+ACA observations, and in dark green, we show the adaptively smoothed X-ray contours drawn at [2, 4, 6, 8, 10]-σ. We further highlight the SZ centroid derived from CARMA measurements (Mantz et al. 2018) with the blue cross. Overall, this figure indicates a coherence between the pressure and density distribution of the ICM seen by ALMA+ACA and X-ray measurements, and the cluster member distribution.
