FI: THE FIRST IMAGE OF A BLACK HOLE - LUCIANO REZZOLLA 
 ELENCO COMPLETO 

DATA: 04-06-2019

SEZIONE DI FIRENZE
I will briefly discuss how the first image of a black hole was obtained by the EHT collaboration. In particular, I will describe the theoretical aspects that have allowed us to model the dynamics of the plasma accreting onto the black hole and how such dynamics was used to generate synthetic black-hole images. I will also illustrate how the comparison between the theoretical images and the observations has allowed us to deduce the presence of a black hole in M87 and to extract information about its properties. Finally, I will describe the lessons we have learned about strong-field gravity and alternatives to black holes. (Luciano Rezzolla)
