Macrostructure of the universe: An ‘unfocused’ eye that sees the big picture

31 marzo 2015

Designed to detect the fossil radiation of the Universe, the Planck satellite, working in tandem with Herschel, can also help to understand the macrostructure of the Universe. A just-published experimental study has detected astronomical sources that may be precursors to galaxy clusters, the largest dynamically stable structures existing in the Universe. These primitive elements have long been sought by astrophysicists since they are crucial for tracing the development of the Universe’s macrostructures. The classic methods used in the quest for large-scale structures are unfortunately difficult to apply (or just completely inapplicable to these objects).
