Looking for signs of the Big Bang in the desert
(PHYSorg.com Space & Earth)

The silence of an immense desolate land in which to search for reverberations coming from the time at which everything began. The Simons Observatory will be built in the Chilean Atacama desert at an altitude of several thousand metres for the purposes of studying primordial gravitational waves which originated in the first instants of the Big Bang. The SISSA research group led by Carlo Baccigalupi and Francesca Perrotta will take part in this prestigious international project which will lead to the realization of an ultra-modern telescope project. Their role will involve studying and removing `signal contaminants`, emissions from our galaxy and other astrophysical objects which interfere with the analysis and study of primordial gravitational waves.
