NASA's Wide Field Infrared Explorer, the WISE telescope, has made it possible to locate what appears to be the cosmic seed from which a black hole will later sprout, that finite portion of space within which there is such a high concentration of mass that none material particle, not even light, can escape from it.
The researchers were looking for black holes in "dwarf" galaxies, which can offer a glimpse into the nurseries of supermassive black holes , very powerful objects that are part of the heart of all galaxies and whose mass is on the order of millions or billions. of solar masses.
Scientists suggest that supermassive black holes would act as a motor for galaxies, but much is still unknown about them. Now, thanks to this study, scientists discovered that black holes do not need a collision to become bulky as previously believed, since black holes in dwarf galaxies are larger than expected, suggesting that black holes in dwarf galaxies are larger than expected. Galaxy mergers are not necessary to create large black holes.
As published in the Astrophysical Journal , supermassive black holes can form very early in the history of the universe or grow in harmony with their host galaxies feeding on surrounding gas, so the theory of galactic collisions to increase the size of a supermassive black hole would be ruled out thanks to this discovery.
