Detection of the kinematic Sunyaev–Zel'dovich effect with DES Year 1 and SPT
Here, we detect the kinematic Sunyaev-Zel'dovich (kSZ) effect with a statistical significance of 4.2σ by combining a cluster catalogue derived from the first year data of the Dark Energy Survey with cosmic microwave background temperature maps from the South Pole Telescope Sunyaev-Zel'dovi...

This measurement is performed with a differential statistic that isolates the pairwise kSZ signal, providing the first detection of the large-scale, pairwise motion of clusters using redshifts derived from photometric data. By fitting the pairwise kSZ signal to a theoretical template, we measure the average central optical depth of the cluster sample, $\bar{τ}$ e =(3.75±0.89)×10 -3 $\bar{τ}$e=(3.75±0.89)×10 -3 .
