| « At the dawn of galaxies: dust enrichment and rise of early black holes » |

Recent observations with JWST and ALMA are transforming our view of the high-redshift Universe, revealing a population of early galaxies that appears significantly more mature than previously anticipated. The slow evolution of the UV luminosity function, the widespread presence of accreting black holes, and the unexpectedly high levels of metal and dust enrichment all suggest that galaxy evolution at cosmic dawn proceeds with remarkable efficiency.
In this talk, I will present a theoretical perspective on these findings, using semi-analytical models and cosmological simulations confronted with JWST and ALMA observations to explore some of the physical processes that have shaped the first billion years of cosmic history. |
