Rashid Alievich Sunyaev (Cyrillic: Раши́д Али́евич Сюня́ев; born March 1, 1943 in Tashkent, USSR) is a Soviet and Russian astrophysicist of Tatar descent. He was educated at the Moscow Institute of Physics and Technology (MS). He became a professor at MIPT in 1974. Sunyaev was the head of the High Energy Astrophysics Department of the Russian Academy of Sciences, and has been chief scientist of the Academy's Space Research Institute since 1992. He has also been a director of the Max Planck Institute for Astrophysics in Garching, Germany since 1996.
Sunyaev and Yakov B. Zel'dovich developed the theory for the evolution of density fluctuations in the early universe. They predicted the pattern of acoustic fluctuations that have been clearly seen by WMAP and other CMB experiments in the microwave sky and in the large-scale distribution of galaxies. Sunyaev and Zel’dovich stated in their 1970 paper, “A detailed investigation of the spectrum of fluctuations may, in principle, lead to an understanding of the nature of initial density perturbations since a distinct periodic dependence of the spectral density of perturbations on wavelength (mass) is peculiar to adiabatic perturbations.” CMB experiments have now seen this distinctive scale in temperature and polarization measurements. Large-scale structure observations have seen this scale in galaxy clustering measurements.
With Yakov B. Zel'dovich, at the Moscow Institute of Applied Mathematics, he proposed what is known as the Sunyaev-Zel'dovich effect, which is due to electrons associated with gas in galaxy clusters scattering the cosmic microwave background radiation.
