Sachs–Wolfe effect : ウィキペディア英語版 | Sachs–Wolfe effect
The Sachs–Wolfe effect, named after Rainer K. Sachs and Arthur M. Wolfe,〔 〕 is a property of the cosmic microwave background radiation (CMB), in which photons from the CMB are gravitationally redshifted, causing the CMB spectrum to appear uneven. This effect is the predominant source of fluctuations in the CMB for angular scales above about ten degrees. == Non-integrated Sachs–Wolfe effect ==
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.
