Rashid Alievich Sunyaev (Tatar: Рәшит Гали улы Сөнәев, Russian: Раши́д Али́евич Сюня́ев; born 1 March 1943 in Tashkent, USSR) is a famous scientist from Russia and Germany. He is an astronomer, which means he studies stars, planets, and everything in space.
He earned his first degree from the Moscow Institute of Physics and Technology (MIPT) in 1966. He later became a professor there in 1974. Sunyaev has led the High Energy Astrophysics Department of the Russian Academy of Sciences. Since 1992, he has been a chief scientist at the Academy's Space Research Institute. He also directs the Max Planck Institute for Astrophysics in Germany. Since 2010, he has been a visiting professor at the Institute for Advanced Study in Princeton.

Discovering the Universe's Secrets
Rashid Sunyaev has made many important discoveries about how the universe works. He often worked with another great scientist, Yakov B. Zeldovich. Together, they helped us understand the early universe.
How the Universe Grew
Sunyaev and Zeldovich created a theory about how tiny changes in the early universe grew over time. They predicted how sound waves moved through the very first universe. These sound waves left a special pattern. This pattern has been clearly seen by space telescopes like WMAP. It also helps us understand how galaxy clusters are spread out in huge groups across the universe.
In 1970, they wrote that studying these patterns could help us learn about how the universe first began. Modern experiments have now confirmed their ideas.
The Sunyaev-Zeldovich Effect
With Yakov B. Zeldovich, Sunyaev also explained something called the Sunyaev-Zeldovich effect. This effect happens when cosmic microwave background radiation (CMB) passes through hot gas in galaxy clusters. The electrons in the gas scatter the CMB light. This scattering changes the CMB's brightness. Scientists use this effect to find and study galaxy clusters.
Black Holes and X-rays
Sunyaev and Nikolay I. Shakura developed a model for how matter falls into black holes. This matter often forms a flat, spinning disk called an accretion disk. They also suggested a way to detect X-rays coming from matter as it spirals into a black hole.
He has also worked on important studies about the very early universe. This includes how hydrogen atoms first formed and how the cosmic microwave background radiation was created.
Leading Space Observatories
Sunyaev led the team that operated an X-ray observatory on the Mir space station. This observatory was part of the Kvant-1 module. In 1987, Kvant made the first discovery of X-rays from a supernova. He also led the team for the GRANAT orbiting X-ray observatory.
Today, his team is working on the Spectrum-X-Gamma International Astrophysical Project. They also work with data from the INTEGRAL spacecraft. At the Max Planck Institute in Germany, he studies high-energy astrophysics and physical cosmology. He also helps interpret data from the ESA Planck spacecraft mission.
