A team of international scientists that includes a Waterloo, Ont. researcher has released a more detailed image of a black hole.
The Perimeter Institute for Theoretical Physics in Waterloo says the new image shows the “swirl” of light around the black hole as it appears in polarized light.
Prof Avery Broderick of the University of Waterloo said: polarized light allows researchers to learn more about the magnetic fields surrounding the black hole in the M87 galaxy.
They believe the new image will further help its understanding of how magnetic fields allow the black hole to “eat” matter and eject powerful energetic jets.
Two years ago, the Event Horizon Telescope (EHT) Collaboration team released the first image of a black hole.
The international collaboration is composed of more than 300 researchers who compiled the image from eight Earth-based telescopes positioned around the world.
Professor Broderick said he helped invent techniques that allowed the team to acquire polarized light, and it took two years for researchers to collect the images.
However, the image the researchers captured is not the closest black hole to Earth, but a hole in the center of the neighbouring galaxy Messier 87, which is easier to see with a telescope.
It is about six billion times the mass of our sun and located about 53 million light-years from Earth. One light-year is equal to 9.5 trillion kilometres.
