NASA and ESA telescopes have revealed ultra strong winds are blowing from black holes. These winds are so powerful and strong that they have the capacity of hindering star formation in the host galaxy.
According to a statement from NASA, telescoped have revealed that ultra strong winds which blow in all directions. These winds are so powerful that they have the capacity to hinder the formation of new stars in the host galaxy.
Two telescopes were employed for the study- NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) and ESA’s XMM-Newton. The focus of the study was PDS 456, a quasar, an extremely bright type of black hole, almost 2 billion light-years away. The results were then analyzed by a team led by Emanuele Nardini of Keele University in the UK.
The quasar PDS 456 was studied at five different times throughout 2013 and 2014 by the two telescopes. The NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) studied the high-energy X-ray observations while the low-energy X-ray observations were done by ESA’s XMM-Newton telescope. The scientists then combined the observation of the two telescopes and the team led by Nardini was able to trace iron dispersed by the quasar’s winds. The data demonstrated that the winds blow outwards from the black hole in a spherical front. After establishing the structure of the quasar winds the research team was able to estimate the strength of the winds. The quasar winds were so strong that they were pushing huge quantities of matter before them dispersing it outwards through the host galaxy and effectively preventing coalescing of matter to generate new stars.10 billion years ago the number of such supermassive black holes were more and their massive winds played a part in shaping the shapes of our present days shapes of galaxies.
Co-author Daniel Stern of NASA’s Jet Propulsion Laboratory said, “For an astronomer, studying PDS 456 is like a paleontologist being given a living dinosaur to study. We are able to investigate the physics of these important systems with a level of detail not possible for those found at more typical distances, during the ‘Age of Quasars.’”
The latest findings have been published in the journal Science.
