Abstract:

The talk is divided in two parts. Mauro Pieroni will first discuss some early Universe mechanisms that leave observable signatures (non-trivial frequency shape, chirality, ...) in the stochastic gravitational wave background (SGWB). In particular, Mauro Pieroni will discuss gauge field production during (and at the and of) axion inflation and (scalar) particle production during preheating. The second part of the talk will focus on methods to detect, and possibly characterize, these signatures with future space based detectors like LISA and Taiji.
