Imprint of DES super-structures on the Cosmic Microwave Background
  Small temperature anisotropies in the Cosmic Microwave Background can be
sourced by density perturbations via the late-time integrated Sachs-Wolfe
effect. Large voids and superclusters are excellent environments to make a
localized measurement of this tiny imprint. In some cases excess signals have
been reported. We probed these claims with an independent data set, using the
first year data of the Dark Energy Survey in a different footprint, and using a
different super-structure finding strategy. We identified 52 large voids and
102 superclusters at redshifts $0.2 < z < 0.65$. We used the Jubilee simulation
to a priori evaluate the optimal ISW measurement configuration for our
compensated top-hat filtering technique, and then performed a stacking
measurement of the CMB temperature field based on the DES data. For optimal
configurations, we detected a cumulative cold imprint of voids with $\Delta
T_{f} \approx -5.0\pm3.7~\mu K$ and a hot imprint of superclusters $\Delta
T_{f} \approx 5.1\pm3.2~\mu K$ ; this is $\sim1.2\sigma$ higher than the
expected $|\Delta T_{f}| \approx 0.6~\mu K$ imprint of such super-structures in
$\Lambda$CDM. If we instead use an a posteriori selected filter size
($R/R_{v}=0.6$), we can find a temperature decrement as large as $\Delta T_{f}
\approx -9.8\pm4.7~\mu K$ for voids, which is $\sim2\sigma$ above $\Lambda$CDM
expectations and is comparable to previous measurements made using SDSS
super-structure data.
