Titre |
Exploring the early universe with the stochastic background of induced gravitational waves |
|
Résumé |
Primordial black hole formation is always accompanied by a large amount of secondary gravitational waves.
The so-called induced gravitational waves are in principle observable by future gravitational waves
detectors. In this talk, I will present how we can use the spectrum of induced gravitational waves to tell
apart the evolution of the universe prior to Big Bang nucleosynthesis. As a practical example, I will use the
latest NANOGrav results on the stochastic background of nanohertz gravitational waves to constrain the
equation of state parameter of the early universe and the mass of the associated primordial black holes. |
