Cosmic donut around black hole clumpy, not smooth
The thick donut-shaped disks of gas and dust that surround most massive black holes in the universe are \'clumpy\' rather than smooth as originally thought, says a study co-authored by an Indian-origin researcher.
London: The thick donut-shaped disks of gas and dust that surround most massive black holes in the universe are 'clumpy' rather than smooth as originally thought, says a study co-authored by an Indian-origin researcher.
Donuts around supermassive black holes were first proposed in the mid-1980s to explain why some black holes are hidden behind gas and dust, while others are not.
The new research is important for understanding the growth and evolution of massive black holes and their host galaxies.
Until recently, telescopes were not able to penetrate some of these donuts, also known as tori, which feed and nourish the growing black holes tucked inside.
This black hole lies at the centre of a well-studied spiral galaxy called NGC 1068, located 47 million light-years away in the Cetus constellation.
