The Simons Observatory (SO), a most advanced network of telescopes aimed at mapping the Cosmic Microwave Background (CMB) with unprecedented precision, has reached a major milestone: the Large Aperture Telescope (LAT) has achieved first light. This marks the full deployment of the observatory, beginning of a new era of cosmological observations that could unveil fundamental aspects of the early Universe, aiming at the detection of cosmological Gravitational Waves from the very first moment after the Big Bang.
SISSA has been the first SO Member Institution in Italy, and plays a crucial role in the SO, leading the Theory and Analysis Committee (TAC). Under the chairship of Prof. Nicoletta Krachmalnicoff, the TAC provides guidance to the collaboration in terms of scientific strategy, ensuring that SO's data analysis and theoretical models maximize the impact of the experiment.
