Gravitational Waves as a Probe of the Early Universe

Explore the fascinating world of gravitational waves and their potential to unlock secrets of the early Universe in this 1-hour 37-minute lecture by Valerie Demcke from CERN, hosted by the Dublin Institute for Advanced Studies. Delve into the current state of gravitational wave searches across various frequency bands, including the emerging evidence for a stochastic gravitational wave background detected by pulsar timing arrays. Examine the data analysis challenges faced by next-generation interferometers and discover innovative approaches for detecting gravitational waves at MHz and GHz frequencies. Gain insights into how these elusive waves, despite their extremely weak interactions, serve as a promising yet challenging probe of the early Universe.
