Scientists have published the most detailed images of galaxies outside ours, revealing their inner workings in unprecedented detail.
The images are based on data collected by Low Frequency Array (LOFAR), a network of more than 70,000 small antennas located in nine European countries. The results are the result of many years of work by a team led by Leah Morabito, Ph.D. from the University of Durham.
The study authors note that more than 13 terabits of raw data per second must be digitized, transferred to the central processing unit and then combined to create a single image, which is the equivalent of more than 300 DVDs.
The new images, made possible by the international nature of the collaboration, are pushing the boundaries of what we know about galaxies and supermassive black holes. A special issue of the scientific journal Astronomy & Astrophysics is devoted to 11 research papers describing these images and scientific results.
