NettetThe ISW e ect (Sachs & Wolfe 1967;Rees & Sciama1968;Martinez-Gonzalez et al.1990; Hu & Sugiyama1994) is a secondary anisotropy in the cos- mic microwave background (CMB), caused by the interaction of CMB photons with the time-evolving potentials from large- scale structure (LSS). Nettetintegrated Sachs-Wolfe (ISW; [4]) effect at late times. The temperature fluctuations in the ISW effect result from the differential redshift effect from photons climbing in and out of time evolving potential perturbations from last scattering surface to the present day.

"NettetA region cooler than surrounding sightlines can be observed if a large void is present, as such a void would cause an increased cancellation between the "late-time" integrated Sachs–Wolfe effect and the "ordinary" Sachs–Wolfe effect. [10] This effect would be much smaller if dark energy were not stretching the void as photons went through it. [11] " - Integrated sachs wolfe effect

The integrated Sachs–Wolfe (ISW) effect is also caused by gravitational redshift, but it occurs between the surface of last scattering and the Earth, so it is not part of the primordial CMB. It occurs when the Universe is dominated in its energy density by something other than matter. If the Universe is dominated by … Se mer The Sachs–Wolfe effect, named after Rainer K. Sachs and Arthur M.

University of Chicago, IL. • Aguiar, Paulo, and Paulo Crawford, Se mer The non-integrated Sachs–Wolfe effect is caused by gravitational redshift occurring at the surface of last scattering. The effect is not constant across the sky due to differences in the matter/energy density at the time of last scattering. Se mer • Sunyaev–Zeldovich effect • Cosmic microwave background spectral distortions Se mer NettetWe discuss the nonlinear extension to the integrated Sachs-Wolfe effect (ISW) resulting from the divergence of the large scale structure momentum density field. The nonlinear ISW effect leads to an increase in the total ISW contribution by roughly two orders of magnitude at l∼1000. This increase, however, is still below the cosmic variance limit of …
