High-temperature plasmas exist inside the clusters of galaxies. The temperature is generally 5-15 keV. These high temperature electrons interact with the 2.726 K cosmic microwave photons and distort the Planck spectrum. This is the well-known Sunyaev-Zeldovich effect. Since some of the clusters have temperature as high as 15 keV, it is extremely important to include the relativistic corrections in the Sunyaev-Zeldovich effect. This has been successfully carried out recently by our group as well as some other groups. In this talk I will discuss the importance of the relativistic corrections. In fact they will be extremely important for the forthcoming short-wavelength observations of the Sunyaev-Zeldovich effect.
