Description
The largest structures in the cosmic web probe the dynamical nature of
dark energy through their integrated Sachs-Wolfe imprints. In the
strength of the signal, typical cosmic voids have shown good consistency
with expectation AISW =
ΔTdata/ΔTtheory = 1, given the
substantial cosmic variance. Discordantly, large-scale hills in the
gravitational potential, or supervoids, have shown excess signals. In
this study, we mapped out 87 new supervoids in the total 5000
deg2 footprint of the Dark Energy Survey at 0.2 < z <
0.9 to probe these anomalous claims. We found an excess imprinted
profile with AISW ≈ 4.1 ± 2.0 amplitude. The
combination with independent BOSS data reveals an ISW imprint of
supervoids at the 3.3σ significance level with an enhanced
AISW ≈ 5.2 ± 1.6 amplitude. The tension with
ΛCDM predictions is equivalent to 2.6σ and remains
unexplained.

The Cosmic Microwave Background (CMB) contains the statistical information about the early seeds of the structure formation in our Universe. Its natural counterpart in the local universe is the distribution of galaxies that arises as a result of gravitational growth of those primordial and small density fluctuations.
