Sachs–Wolfe effect

Target entity: Sachs–Wolfe effect
Context triple: [Bardeen potential, usedToAnalyze, Sachs–Wolfe effect]

• A. Sunyaev–Zel’dovich effect
  The Sunyaev–Zel’dovich effect is a distortion of the cosmic microwave background radiation caused by high-energy electrons in galaxy clusters, used as a powerful probe of large-scale structure and cosmology.
• B. cosmic microwave background
  The cosmic microwave background is the faint, nearly uniform afterglow radiation permeating the universe, providing a snapshot of the cosmos about 380,000 years after the Big Bang.
• C. Gamow factor
  The Gamow factor is a quantum mechanical tunneling probability term that quantifies the likelihood of charged particles overcoming their mutual Coulomb barrier, especially in nuclear fusion processes.
• D. Lemaître–Hubble law
  The Lemaître–Hubble law is the fundamental cosmological relation that expresses the proportionality between a galaxy’s recessional velocity and its distance, providing the first observational evidence for the expansion of the universe.
• E. Zeldovich approximation
  The Zeldovich approximation is a cosmological model that provides a simple, first-order description of the growth of large-scale structure in the universe by tracking how matter elements move under gravity from initially small density perturbations.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Sachs–Wolfe effect
Target entity description: The Sachs–Wolfe effect is a cosmological phenomenon in which gravitational potential fluctuations imprint temperature anisotropies on the cosmic microwave background radiation, especially on large angular scales.
