    Description

    The detection of gravitational waves from merging black holes opened a new era in astronomy and cosmology. A significant fraction of detected binary black hole events has shows two characteristics unexpected by part of the community: large progenitors masses and low effective spin. This fact suggested that those black holes might have a primordial origin and that they may constitute a fraction of the dark matter. In this talk I show how, using clustering properties of GWs events and cross-correlating them with future large-scale structure surveys, it is possible to discriminate between mergers of primordial progenitors or mergers of black holes coming from stellar evolution. Moreover I will show what we can understand of Early Universe physics in case part of the dark matter is made of these compact objects.
