An article published in the journal “Astronomy & Astrophysics” reports a study on the Andromeda galaxy based on the best image captured in the microwave band. A team of researchers coordinated by Professor Elia Battistelli of the physics department at Sapienza used the Sardinia Radio Telescope (SRT) and its ability to work at high radio frequencies to create a map of Andromeda at 6.6 GHz, a frequency detected for the first time that fills a gap in the studies of the galaxy considered a sort of sister of the Milky Way. This helped to better understand the processes taking place within Andromeda identifying areas of star formation.
