2010/12/27
A number of recent proposals for a quantum theory of gravity are based on the idea that spacetime geometry and gravity are derivative concepts and only apply at an approximate level. There are two fu...
Level Crossing Analysis of Cosmic Microwave Background Radiation: A method for detecting cosmic strings
Cosmic Microwave Background Radiation detecting cosmic strings
font style='font-size:12px;'>
2010/12/27
In this paper we study the footprint of cosmic string as the topological defects in the very early universe on the cosmic microwave background radiation. We develop the method of level crossing analy...
