Gravitational waves from primordial fluctuations - Guillem Domenech (26 October 2022)

A QMUL Astronomy Unit Cosmology & Relativity Seminar

Fluctuations in the primordial universe inevitably induce gravitational waves. The resulting gravitational wave spectrum not only contains information about the spectrum of such fluctuations but on the composition of the universe at the time of wave generation. In this talk, I will explain the generation of such induced gravitational waves and I will discuss the gravitational waves signals of a primordial black hole dominated early universe.
