Probe Combination in Cosmology: Status and Prospects

Giorno 9 marzo 2026, con inizio alle ore 15:00, presso la Sala Conferenze del DFA, il Prof. Carlo Baccigalupi (SISSA, Trieste, Italy) terrà un seminario dal titolo Probe Combination in Cosmology: Status and Prospects.

Il seminario appartiene al ciclo degli Highlights in Frontier Physics, nell'ambito delle attività del Dottorato di ricerca in Fisica.

Tutte le persone interessate sono invitate a partecipare.

Abstract. One of the major challenges in the context of the Cosmic Microwave Background (CMB) radiation is to detect a polarization pattern, the so called B-modes of CMB polarization, that are thought to be directly linked to the space-time fluctuations present in the Universe at the very first instants of life. To date, several challenges have prevented to detect the B-modes partly because of the lower sensitivity of the detectors. Our own Galaxy is observed in this context as a foreground contamination. However the awareness of improving the modeling of its polarized emission has been constantly increase not only to assess the cosmological signals but also to provide new insights onto the Galactic magnetic field probed with the Galactic polarized emissions, e.g. synchrotron and thermal dust.  This is particularly relevant in order to better characterize the foreground contamination for future CMB experiments (e.g. SO, LiteBIRD, CMB-S4 ), where high sensitivities are expected to be achieved.

Bio. Carlo Baccigalupi is a Full Professor of Cosmology and Astrophysics at SISSA, Trieste. His research focuses on the Cosmic Microwave Background (CMB), aiming to unravel the universe's origin and the nature of Dark Energy. A leading expert in data analysis and phenomenology, he plays a key role in major international missions like LiteBIRD and the Simons Observatory. Beyond the math, he is a dedicated mentor, guiding the next generation of physicists through the mysteries of the early universe.
