Seminario di cosmologia

Il 4 novembre alle ore 11 presso la sala riunioni C400,Matteo Braglia (New York University) terra' un seminario dal titolo

Detecting gravitational waves from inflation with LISA

Abstract

Inflationary mechanisms beyond the standard single-field slow-roll paradigm may give rise to Stochastic Gravitational Wave Backgrounds (SGWB) within the sensitivity range of the LISA satellite. This talk, a result of collaboration within the LISA Cosmology Working Group, delves into the potential of LISA in scrutinizing Early Universe Physics. Using a recently developed data analysis pipeline, I will present forecast constraints on the model parameters and discuss the implications of these forecasts for inflationary model builders. In passing, I will also discuss the impact that a large SGWB, which acts as an extra source of noise for LISA, may have on the detection of single events from binaries of Massive and Stellar Origin Black Holes, as well as Galactic White Dwarfs.
