‘Green Pea’ Galaxies May Have Reheated the Universe After Cosmic Dark Age

Swiss scientist may have find the answer to a troubling secret about the former evolution of our creation . After the Big Bang , the universe cool down down for a billion year in a variety of cosmic dark age . But then it mysteriously reheat . negatron and protons that had been happily joined in hydrogen atom were pull aside again during a period recognize as the “ cosmic reionization . ” What could have done this ?

In a raw paper inthe journal Nature , researchers from the University of Geneva name their psychoanalysis of so - called “ green pea plant ” galaxies . No one knewthese galax existed until 2007 . They got their nickname by demonstrate up as unclouded green blobs on theSloan Digital Sky Survey(SDSS ) , and because they were such compact little thing . But do n’t permit their small sizing fool you : green pea galaxies are wizard factories , and they pack a wallop in terms of how much energy they let loose .

Since 2013 , scientistshave suspectedthey gave off enough energy to ionize hydrogenfloating between galaxies . This is no little effort . It ’s not that hard to divest an negatron from a H atom , but most galaxies have so much rubble and debris that their radiation sickness does n’t make it into intergalactic space . So how could the galaxies that exist at the metre be capable of emitting sufficient energy to reheat the intact existence ?

To try immature pea galaxy were different , the Swiss researchers pored over the SDSS datum and notice 5,000 of them . Then theyselected five immature pea galaxiesamong the 5,000 , and studied them with the Hubble Space Telescope . And they found that one of those galaxies , J0925 , is n’t just leaking photon able of ionizing hydrogen — those photon are actively being force out .

This put up a lose piece to the fretsaw puzzle of how the early world evolved . The Big Bang chip in the creation its first kick of heat , after which thing slowly cooled down . Electrons found protons and ions became atoms . After some time , matter condense even more , forming stars and galaxies .

Then , when the universe of discourse was about a billion geezerhood onetime , the green pea wandflower went to study . They formed stars cursorily and violently . Thestar explosions and galactic windsin the green pea galax turn out enormous amount of energy off into space , stripping negatron off atoms once again and have the nifty cosmic deionization , thereby reheating the population .
