Scheme of the detection of baryons in intergalactic gas

An article published in the journal “Nature” describes the discovery of the missing ordinary matter in the universe. A team of researchers led by Fabrizio Nicastro of INAF, Rome, Italy, discovered what is technically called baryonic matter after having searched it for almost twenty years using ESA’s XMM-Newton space telescope keeping under observation the quasar 1ES 1553+113 up to find the traces of the baryons hidden in the hot gas present among the galaxies.
