Query: Evidence for a high-z ISW signal from supervoids in the distribution of
  eBOSS quasars   The late-time integrated Sachs-Wolfe (ISW) imprint of $R\gtrsim
100~h^{-1}{\rm Mpc}$ super-structures is sourced by evolving large-scale
potentials due to a dominant dark energy component in the $\Lambda$CDM model.
The aspect that makes the ISW effect distinctly interesting is the repeated
observation of stronger-than-expected imprints from supervoids at
$z\lesssim0.9$. Here we analyze the un-probed key redshift range $0.8<z<2.2$
where the ISW signal is expected to fade in $\Lambda$CDM, due to a weakening
dark energy component, and eventually become consistent with zero in the matter
dominated epoch. On the contrary, alternative cosmological models, proposed to
explain the excess low-$z$ ISW signals, predicted a sign-change in the ISW
effect at $z\approx1.5$ due to the possible growth of large-scale potentials
that is absent in the standard model. To discriminate, we estimated the
high-$z$ $\Lambda$CDM ISW signal using the Millennium XXL mock catalogue, and
compared it to our measurements from about 800 supervoids identified in the
eBOSS DR16 quasar catalogue. At $0.8<z<1.2$, we found an excess ISW signal with
$A_\mathrm{ ISW}\approx3.6\pm2.1$ amplitude. The signal is then consistent with
the $\Lambda$CDM expectation ($A_\mathrm{ ISW}=1$) at $1.2<z<1.5$ where the
standard and alternative models predict similar amplitudes. Most interestingly,
we also detected an opposite-sign ISW signal at $1.5<z<2.2$ that is in
$2.7\sigma$ tension with the $\Lambda$CDM prediction. Taken at face value,
these moderately significant detections of ISW anomalies suggest an alternative
growth rate of structure in low-density environments at $\sim100~h^{-1}{\rm
Mpc}$ scales.
