Testing gravity against the early time integrated Sachs-Wolfe effect
Open accessAbstract
A generic prediction of general relativity is that the cosmological linear density growth factor $D$ is scale independent. But in general, modified gravities do not preserve this signature. A scale dependent $D$ can cause time variation in gravitational potential at high redshifts and provides a new cosmological test of gravity, through early time integrated Sachs-Wolfe (ISW) effect-large scale structure (LSS) cross correlation. We demonstrate the power of this test for a class of $f(R)$ gravity, with the form $f(R)=\ensuremath{-}{\ensuremath{\lambda}}_{1}{H}_{0}^{2}\mathrm{exp}(\ensuremath{-}R/{\ensuremath{\lambda}}_{2}{H}_{0}^{2})$. Such $f(R)$ gravity, even with degenerate expansion history to $\ensuremath{\Lambda}\mathrm{CDM}$, can produce detectable ISW effect at $z\ensuremath{\gtrsim}3$ and $l\ensuremath{\gtrsim}20$. Null-detection of such effect would constrain ${\ensuremath{\lambda}}_{2}$ to be ${\ensuremath{\lambda}}_{2}>1000$ at $>95%$ confidence level. On the other hand, robust detection of ISW-LSS cross correlation at high $z$ will severely challenge general relativity.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
