ignominious holes are the strong , dumb character — an age - old enigma . Hubble estimates that there are roughly100 millionblack holes in our galaxy alone , but because their gravitational pulling isso intense , light ca n’t escape . So even with the most advanced equipment,“stray ” black holes wandering in space are virtually unsufferable to find out .
Butnew researchfrom a team of scientists at Keio University in Japan could be a biz - changer in the hunt for these elusive giants . Initially , the group set out to watch the molecular gasolene around a supernova remnant calledW44 , located 10,000 lightyears away from our solar scheme .
However , after using the ASTE Telescope in Chile and the 45 - m Radio Telescope at the Nobeyama Radio Observatory in Japan , the researchers found foreign motion within that molecular cloud , which they nicknamed the “ hummer , ” since it was move at 223,694 miles per minute . The squad put forward a hidden black hole could be induce this unusual activity , and decided to canvas the matter further . Their findings werepublishedin January in Astrophysical Journal Letters .
“ Most of the Bullet has an enlarge move with a velocity of 50 km / s , but the bakshish of the Bullet has a speed of 120 km / s , ” Keio University grad student Masaya Yamada , the bailiwick ’s drawing card , saidin a press release . “ Its energizing vim is a few tens of times bombastic than that inject by the W44 supernova . It seems unacceptable to generate such an energetic swarm under average environments . ”
The team suggest that one of two scenarios could have caused the Bullet : an “ detonation good example ” or an “ outbreak model . ” In the first scenario , dull gas stuffy to the mordant hole triggers an explosion , quicken gas towards us . In the second , the sinister hole yield rise to fast - run flow of gas . The group is n’t yet trusted which of the two theory is more probable , but will investigate the situation further using the Atacama Large Millimeter / submillimeter Array ( ALMA ) in Chile .
The researcher hope that their method acting , of studying apparent movement inside accelerator cloud , will help reveal more black holes , because these tricksters wo n’t let out themselves . In January , scientists at the university of Durham and Southampton regain shroud “ monster disgraceful holes ” at the heart and soul of extragalactic nebula near our own Milky Way , shroud behind cloud of gas and debris . Perhaps the Keio University method will help us find some of these sneaky beasts , and other smaller black mess in our galaxy , too .
“ We found a fresh way of bring out stray black gob , ” team member Tomoharu Oka said .
