Research Abstract

Anisotropies in the temperature of the cosmic microwave background radiation exhibit density inhomogeneity in the early Universe of age 380kyr.We have probed generation of primordial fluctuations during cosmic inflation which seeded these temperature anisotropies from their observations and discovered a modulation in their spectrum which is realized with the probability less than one in ten thousand and clarified its effects on determination of cosmological parameters to show that it is mandatory to take the modulation into account to analyze the data of PLANCK.
