| 13:30 - 15:00 Weekly Seminar Knocking at the Door of the Cosmic Microwave Background (CMB) School ASTRONOMY I will talk about the model-building approach to describe the very early universe, which can address the several unresolved puzzles of the hot Big Bang Cosmology. The formation of topological defects as a result of phase transition is another promising phenomenon to probe the unseen universe. I will briefly describe the formation of topological defects and the emission of the Stochastic Gravitational-Wave Background (SGWB). One of the topological defects, Cosmic Strings, may have an imprint on the CMB. I will briefly talk about how we can see their footprints in the CMB and constrain the cosmic string tension. Recently, (International Pulsar ... |
