| Sammanfattning≠ | The Sunyaev-Zel'dovich effect is a phenomenon in which the cosmic microwave background (CMB) is distorted as photons travel through hot gas in galaxy clusters. Proposed by Rashid Sunyaev and Yakov Zel'dovich in 1972, this effect provides a powerful method for detecting distant galaxy clusters and measuring fundamental cosmological parameters without distance assumptions. | Weak gravitational lensing occurs when light from distant sources bends slightly as it travels through the universe, passing through the gravitational fields of matter concentrations. Proposed theoretically by Nick Kaiser in 1992, this subtle effect has become one of the most powerful cosmological probes, directly revealing the distribution of all matter (dark and luminous) across cosmic distances. |
