European Southern Observatory in the Month of June 2013 gathered the most detailed observations ever of the dust around a huge black hole at the centre of an active galaxy with the help of Very Large Telescope Interferometer (VLTI).
The astronomers found that the glowing dust is located above and below the torus rather than being located in a dough nut shaped torus around the black hole.
As per the observations it was found that dust is being pushed away from the black hole as a cool wind disrupting the current theories and revealing, evolving supermassive black hole and it’s interacting with surroundings.
Summing up all the last twenty years study by astronomers it was found that almost all galaxies have a huge black hole at their centre. Few of these black holes are growing by drawing in matter from their surroundings, which in turn is creating the process of formation of most energetic objects in the Universe: active galactic nuclei (AGN).
According to the new observations of a nearby active galaxy called NGC 3783, harnessing the power of the VLTI at ESO’s Paranal Observatory in Chile, have given a team of astronomers a surprise.
The newly-discovered dust forms a cool wind which stream outside from the black hole. This wind must play an important role in the complex relationship between the black hole and its environment. The new observation made is going to lead a paradigm shift in the understanding of AGN. They are direct evidence that dust is being pushed out by the intense radiation.
