With new algorithms and supercomputers, an incredibly detailed radio map of the universe has been created. Now astronomers can look at radio data of galaxies with much more precision. This research was published in Nature Astronomy by Leiden University Ph.D. student Frits Sweijen and colleagues.
“This single map has almost as many pixels as previous maps of the entire sky had,” says Frits Sweijen. The researchers solved the blurring effect of UV radiation in our atmosphere: With special software they managed to correct for this interference. Supercomputers in Leiden and Amsterdam used their enormous computing power to ensure that this also went fairly quickly.
