stargazer at the University of Texas and the Space Telescope Science Institute have machinate a agency to open visual randomness from satellite images , revealing a coup d’oeil of our cosmos in its babyhood . They sharedtheirfindingson the preprint host arXiv .
The current hypothesis about our cosmos ’s early day goes something like this : In the outset , there was the Big Bang , with all its attendant spark and electrical tutelage . Some sentence after that , all go dark . Then the first wandflower bloomed , work with them cloud of energy thatre - ionizedand lit up the sky . endearing as this story sound , it ’s been difficult to turn up , as these old , one-time , former galaxies have long since grow picket and indistinct amidst the brilliant chaos of new celestial going - on .
tether author Rachael C. Livermore and her colleagues calculate that if they could dip or shut out some of that newer radiance , they might suffer a fortune of finding the ancient galaxies .
Their solution : a technique called ripple decomposition reaction , which can mask high - loudness brightness the same way noise - canceling headphones shut out sound .
“ The wavelet transform allows us to decompose an image into its component on different forcible shell , ” the authors write . “ Thus , we can insulate structure on heavy graduated table … and remove them , set aside objects on modest scale to be identify more easily . ”
They apply this new method to Hubble scope image of sensation cluster Abell 2744 and MACS 0416 . And it worked like a good luck charm . Selectively turning down the brightness revealed 167 never - before - see galaxies , all quite elderly and faint .
The writer say their discovery provide “ hard support ” for the theory of re - ionisation . They and other astronomers will have shipload of new images to examine quite presently , as theJames Webb Space Telescopeis schedule to launch in 2018 .
