These oscillons, formed after the rapid expansion of the Universe during the inflationary period, can generate detectable gravitational waves when they decay.
In their study, Kavli Institute for the Physics and Mathematics of the Universe Project Researcher Kaloian D.
The findings provide a novel test of the early Universe dynamics independent of the conventionally studied cosmic microwave background radiation. The discovery of these gravitational waves would establish a new window into the Universe’s earliest moments, and could help shed light on some of the pressing fundamental questions in cosmology.
With the ongoing development of gravitational wave detectors and supercomputing resources, we can expect to gain even more insights into the Universe’s early moments in the coming years. Overall, the new study demonstrates the power of combining theoretical models with advanced computational techniques and observations to uncover new insights into the Universe’s evolution.Reference: “Enhanced Gravitational Waves from Inflaton Oscillons” by Kaloian D.
