“The black holes have 8 or 30 times the mass of our sun. This is the first Double system Black holes, where we observed such a huge difference between the masses, “says Roberto Cotesta from the” Astrophysical and Cosmological Relativity Theory “department at the Albert Einstein Institute in Potsdam. “This large difference in mass means that we can measure several properties of the system more precisely: its distance from us, the angle at which we look at it and how quickly the heavy black hole rotates around its axis.”
Better detectors
The researchers discovered the fascinating system, which is marketed under the name GW190412, on April 12, 2019. It is a premiere insofar as the same instruments have so far only been used Double systems were discovered on black holes that had approximately the same mass. The black holes, which rotate around each other and their own axis, could be discovered through further development and better sensitivity of the detectors used. They are the proof that a more diverse so far hidden population Double systems give as known so far.
