Blasting winds from “black hole” equivalent to 10 times the mass of the SunRaymond Billings (Author) Published Date : Feb 22, 2015 12:27 IST
Astronomers just found that winds blasting out of the gigantic black holes are so strong that they can inhibit the dawn of new stars.
Two space telescopes have been trained on a colossal black hole in order to measure the strength of this brutal stream of air.
It has been confirmed that these winds are blowing in an outward direction without being specific towards any particular way. This has baffled scientists even further.
This situation is demonstrating how such black holes have impact on the evolution of their galaxies.
An international panel of astronomers has carried out this research with the assistance of the XMM-Newton and Nustar telescopes under the supervision of both ESA and NASA.
Prof Fiona Harrison of the California Institute of Technology, Nustar's principal investigator stated that We know that black holes in the centre of galaxies can feed on matter, and this process can produce winds. This is thought to regulate the growth of galaxies.
The diverse wavelengths of light appearing from the remote black hole which is almost 2 billion light years away called PDS has been taped concurrently by these two telescopes. What was observed was that they illuminate brightly with various kinds of light which makes it a quasar.
Nustar is focused on high-energy X-rays whereas XMM-Newton on low-energy ones and XMM-Newton has already indentified wind blowing in the direction of the Earth from PDS 456 as iron atoms being carried by the enormous rush obstructs X-rays in a distinctive method. Apart from that it has assisted in allowing astronomers in calculating that the wind was moving at a 1/3 speed of light.
The addition of high-energy observations received by Nustar has helped the group to identify various signs of iron which was sprinkled around the edges proving that the wind most probably gusts out in what we can only call a circular blast.
Prof Harrison said that Knowing the speed, shape and size of the winds, we can now figure out how powerful they are.
This power is has be under strict observation since it is around 10 times the mass of the Sun blowing out annually alongside a trillion times more energy in comparison to the emission of our star.
Now we know that quasar winds significantly contribute to mass loss in a galaxy, driving out its supply of gas, which is fuel for star formation, said Dr Emanuele Nardini from Keel University in the UK, the study's lead author.
This study provides a unique view of the possible mechanism that links the evolution of the central black holes to that of their host galaxies, over cosmic time.
