Astrophysicists have taken a huge leap of realization in understanding the evolution of supermassive black holes. Using data from Hubble and two other space telescopes, Italian researchers have established the finest evidence yet for the seeds that eventually mature into these cosmic giants.
Year after year astronomers has researched and discussed the possible formation of the first generation supermassive black holes. They came up with many retorts but nothing came as adjacent as it seems now. Thanks to Italian scientist Fabio Pacucci whose team has identified two objects from the premature universe which could be the key to open the lock about the long-haul mystery of ‘birth of supermassive black hole’. These two substances exemplified the most promising black hole seed candidates found so far in the history of cosmological science.
With the help of NASA’s Chandra X-ray Observatory, the NASA/ESA Hubble Space Telescope, and the NASA Spitzer Space Telescope the group have been able to analyze the data from a computerized based mathematical model and finally been able to find the two substances. Both of these recently revealed black hole seed candidates seem to be less than a billion years old after the ‘Big Bang’ incident and have an initial mass of about 100 000 times the Sun.
Fundamentally, there are two main theories to explicate the formation of super massive black holes in the premature universe. The first theory suggests that the seeds grow out of black holes with a mass about ten to a hundred times larger than our Sun, as expected for the collapse of a massive star. The black hole seeds then propagated through fusions with other trivial black holes and by pulling in gas from their surroundings. However, at this stage, they have to grow at a remarkably high rate to reach the mass of super massive black holes already exposed in the billion years young universe.
The recent findings, however, contradicts some of the old theories as the results indicates that at-least some of these massive cosmic giants with mass 100 000 times greater than that of the mass of Sun formed unswervingly when a massive cloud of gas collapsed. In this circumstance, the evolution of the black holes would be galvanizing, and would ensue more quickly. This new result helps to explain why we see super massive black holes less than one billion years after the Big Bang.
A lot of controversies still prevails over which path these black holes takes, said co-author Andrea Ferrari also of Scuola Normale Superiore. “Our work suggests we are converging on one answer, where black holes start big and grow at the normal rate, rather than starting small and growing at a fast rate.”
These two newly revealed black hole seed candidates match the theoretical predictions, yet auxiliary observations are needed to confirm their true nature. To distinguish between the two formations theories, it will also be obligatory to find more candidates.
The research will be further enhanced as the team is scheduling to conduct follow-up observations in X-rays and in the infrared range. The purpose is to check the properties expected for a black hole seeds found in these two objects. Upcoming observatories, like the NASA/ESA/CSA James Webb Space Telescope and the European Extremely Large Telescope, will definitely put a dent in the field of astrophysics and cosmology, by perceiving even smaller and more distant black holes.
