L’evento ha lo scopo principale di permettere l’esplorazione del territorio (geologica) utilizzando tecnologie innovative che permettono la piena fruibilità a tutti gli studenti anche a coloro affetti da disabilità motorie. I partecipanti potranno vivere una giornata da esploratori, come veri geologi, attraverso l’utilizzo della REALTA’ VIRTUALE IMMERSIVA.
In the last decade, huge efforts have been made to measure the polarization of the Cosmic Microwave Background, in order to find the imprints on its polarized anisotropies of a stochastic background of primordial gravitational waves that might have been produced during the inflationary phase, commonly referred as CMB B-modes. These primordial anisotropies are expected to peak at large angular scales (> degree). To date, several challenges have prevented the detection of primordial B-modes mostly because of the diffuse polarized radiation coming from the Milky Way. On smaller angular scales, extragalactic polarized emission from Radio and Star-forming galaxies represent the major contamination to CMB polarization. To date, several ground-based experiments are updating their cameras to achieve high sensitivities in order to ultimately constrains CMB B-modes. As a consequence, an increasing number of polarized radio sources will be detected and surveyed in the forthcoming CMB measurements. In my talk I will outline the state of the art of CMB B-modes constraints and show the forecasts for extragalactic sources that will be detected in mm and sub-mm wavelengths.
