Jam packed issues filled with the latest cutting-edge research, technology and theories delivered in an entertaining and visually stunning way, aiming to educate and inspire readers of all agesHidden information in maps of galaxies spread across the universe could soon come forth, thanks to a new way of interrogating the data that preserves the three-dimensional nature of these maps.
However, the calculating power required to statistically analyze this three-dimensional galaxy data is fiendish, and so, for efficiency, the 3D data has traditionally been compressed down into what are called"n-point correlation functions," the"n" referring to a number . N-point functions are popular because they speed up processing time and are more efficient to use, but today's algorithms are sophisticated enough to bridge the gap and enable the full, uncompressed data to be analyzed.
Their results show a factor of between three and five improvement in detail and accuracy in the FLI analysis compared to two- and three-point correlation functions. This extra detail indicates that there is information that is being hidden in the old way of doing things. When it comes to the dark universe and how it has affected the growth of galaxies in large-scale structures across the universe, there's still much that we're, well, in the dark about. But with FLI, it's possible to describe the dark-matter distribution associated with the galaxies in the map.
