Galaxies and their central supermassive fatal gob grew in tandem , the outcome of countless collision and mergers between ancient , belittled galaxy . But galax sometimes merged without combining their black holes , eject some of these objects out into the deepness of open space .
According to a computer simulation by Valery Rashkov and Piero Madau at UC Santa Cruz , a shocking bit of these give up black maw might be encounter in the Milky Way ’s halo , which is a jumbo outlying region of gas find beyond our Galax urceolata ’s stars . There ’s considerable variance in full term of just how many black holes are out there — Rashkov and Madau place the number of dark holes between as low as 70 and and as gamey as 2,000 .
These objects are what the researchers refer to as “ seed ” black hole . These intermediate - sized grim holes were once find at the inwardness of early collections of stars and petrol — these structures were n’t big enough to be consider galaxies in their own right , but they combined as the building engine block for galaxy like the Milky Way . While a good number of these original , relatively modest shameful hole would have blend together to imprint the current harvest of supermassive black holes , but the pandemonium of these intergalactic mergers could have entrust some of the black holes stranded in the far area of space .
While most of these rogue black trap would be moderately much impossible to find , some of them might have brought entire whizz clump and clustering of drear matter along with them . If that ’s the case , we should be able to make out the light of those clusters in the Milky Way ’s doughnut . For more , hold in outNew Scientistand the original paper atarXiv .
