ISLAMABAD: Winds blasted out by the giant black holes found at the centre of galaxies are strong enough to stunt the birth of new stars, astronomers have found.
By training two space telescopes on a supermassive black hole with the mass of a billion Suns, they measured the strength of its ferocious winds, BBC reported.
The team also confirmed that these winds blow outwards in every direction, an idea that had been tricky to prove.
The work shows how such black holes can affect the evolution of their galaxies.
It was conducted by an international team of astronomers using the telescopes XMM-Newton and Nustar, run by the European Space Agency (Esa) and Nasa respectively.
“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,” said Prof Fiona Harrison of the California Institute of Technology, Nustar’s principal investigator.
The two telescopes simultaneously recorded different wavelengths of light coming from their distant target: a black hole two billion light-years away known as PDS 456. It shines brightly with many types of light, making it a quasar.
Nustar specialises in high-energy X-rays while XMM-Newton views low-energy X-rays.
