He won the top spot in the Eso - European Southern Observatory's picture of the week, the image captured by the Vlt Survey Telescope, the telescope built byInaf in Naples that made a major scientific achievement possible.
The image is part of the paper "Formation of an ultra-diffuse galaxy in the stellar filaments of NGC3314A: caught in act?" as part of the Vegas project - the Vst Early-type galaxy survey, published last summer in Astronomy & Astrophysics Letters, whose authors, afterEnrichetta Iodice, a researcher at Inaf in Naples and principal investigator of Vegas, include Frederick Antonio La Marca, who graduated in Physics with a major in Astrophysics in February 2021, summa cum laude, whose contribution within the VEGAS collaboration focused on the fainter galaxy populations that are thought to be the 'building blocks' that formed the major galaxies.
The photograph captured two overlapping but gravitationally non-interacting spiral gal axies and, hidden near them, an ultra-diffuse galaxy that provides new clues to a yet-to-be-tested hypothesis that these types of galaxies can also form as a result of gravitational interactions between galaxies or between galaxies and the surrounding interstellar medium.
