SunyaevZeldovicheffekten
The Sunyaev-Zel'dovich effect is a phenomenon observed in the cosmic microwave background (CMB) radiation. It occurs when CMB photons scatter off hot, ionized gas in galaxy clusters. This scattering causes a distortion in the CMB spectrum, leading to a slight deficit of photons at certain frequencies and an excess at others. The effect is named after Rashid Sunyaev and Yakov Zel'dovich, who predicted it in 1970.
There are two primary forms of the Sunyaev-Zel'dovich effect: the thermal Sunyaev-Zel'dovich (tSZ) effect and the
The Sunyaev-Zel'dovich effect is a powerful tool for studying galaxy clusters and cosmology. By measuring the
