Scientists have published a new, detailed radio image of the Andromeda galaxy—the Milky Way’s sister galaxy—which will allow them to identify and study the regions of Andromeda where new stars are born.
The study—which is the first to create a radio image of Andromeda at the microwave frequency of 6.6 GHz—was led by University of British Columbia physicist Sofia Fatigoni, with colleagues at Sapienza University of Rome and the Italian National Institute of Astrophysics. It was published online in Astronomy and Astrophysics.
“This image will allow us to study the structure of Andromeda and its content in more detail than has ever been possible,” said Fatigoni, a Ph.D. student in the department of physics and astronomy at UBC. “Understanding the nature of physical processes that take place inside Andromeda allows us to understand what happens in our own galaxy more clearly—as if we were looking at ourselves from the outside.”
