A scientific consortium discovered an enormous black hole growing at a more rapid pace than its host galaxy.
The finding comes to challenge the hand-in-hand development theory in which the majority of black holes develop at approximately the same pace as their host galaxies.
Scientists from Yale University, Oxford University, ETH Zürich, University of Hawaii, the Max-Planck Institute and the INAF-Osservatorio Astronomico di Roma were mapping the growth across cosmic time of supermassive black holes when they came upon the enormous black hole formed approximately two billion years following the Big Bang.
Using the Hawaii based 10-meter Keck telescope, the scientists discovered the enormous black hole at the heart of the CID-947 galaxy. The observations concern the enormous black hole at an early age accounting for 14 percent of the current age relative to the Big Bang.
“Our survey was designed to observe the average objects, not the exotic ones. This project specifically targeted moderate black holes that inhabit typical galaxies today. It was quite a shock to see such a ginormous black hole in such a deep field”,
stated one of the astrophysicists and co-authors of the study, C. Megan Urry.
The enormous black hole is at the center of CID-947 and measures 7 billion solar masses compared to its host galaxy. The mass of CID-947 is in line with that of the majority of galaxies, being normal-sized.
So, at the heart of a normal-sized galaxy lies a gigantic black hole that challenges previous knowledge of the growth relationship between host galaxies and the black holes at their center. At the same time, it proves difficult to not reasses the hypothesis that as black holes expand, the radiation they emit curtails star creation.
At the time of the finding, the scientists declared that stars were still forming in CID-947, pointing that the galaxy shows signs of continual growth.
The findings of the scientific consortium feature in the latest issue of the Science journal.
