Tracing the Cosmos with Stochastic Gravitational-Wave Background

 

Abstract: Hybrid inflation provides a rich framework for understanding the early universe’s dynamics and its connection to observable cosmic structures. This talk will explore the role of hybrid inflation in generating topological defects and the stochastic gravitational wave background, emphasizing model-building approaches to connect theoretical predictions with observations. I will discuss the potential origins of the signals detected in the NANOGrav 15-year dataset and how they relate to cosmic phenomena such as scalar-induced gravitational waves and cosmic strings. Furthermore, we will delve into the intriguing possibility of primordial black hole formation during hybrid inflation and its implications for current and future astrophysical observations.  I will also talk about weighted Morphology and its implications on topological defects. This presentation aims to bridge theoretical insights with observational data, shedding light on the intricate interplay between inflationary physics, gravitational waves, and primordial black holes.
