Title: Gravitational waves from the early Universe: How, When & Why?

Abstract: In this talk, I will discuss recent results for New physics beyond the Standard Model of particles and Cosmology relating to Gravitational Waves signals in form of stochastic backgrounds. In particular, I will focus on the cases of First Order Phase Transitions and inflation for Primordial Black Holes Dark Matter. I will motivate why Dark Matter is one of the main reasons for searches of new gravitational waves signals from early Universe. Implications for space-based gravitational waves interferometers such as TAIJI, LISA, TianQing projects, as well as for Pulsar-timing radio-astronomy such as NANOGrav are discussed.
