Revisiting cosmic microwave background radiation using blackbody radiation inversion

Abstract Blackbody radiation inversion is a mathematical process for the determination of probability distribution of temperature from measured radiated power spectrum. In this paper a simple and stable blackbody radiation inversion is achieved by using an analytical function with three determinable...
