Expanding Horizons: Understanding the EHT’s black hole discoveries

By: 

Perimeter Institute: 11/04/2019

"The Event Horizon Telescope (EHT) is a project to create a large telescope array consisting of a global network of radio telescopes and combining data from several very-long-baseline interferometry (VLBI) stations around the Earth. The aim is to observe the immediate environment of the supermassive black hole Sagittarius A at the centre of the Milky Way, as well as the even larger black hole in the centre of the supergiant elliptical galaxy Messier 87, with angular resolution comparable to the black hole's event horizon." - Wikipedia

From a Perimeter Institute email.

The Event Horizon Telescope (EHT) collaboration will announce a “groundbreaking result” regarding black holes on April 10 at 9 a.m. ET.

• Shep Doeleman, EHT Director, Centre for Astrophysics, Harvard & Smithsonian.
• Dan Marrone, Associate Professor of Astronomy, University of Arizona.

Following the announcement, at 11 am ET, black hole experts will explore the implications of the findings during “Expanding Horizons,” a live panel discussion at Perimeter Institute.

On the panel will be:

• Robert Myers, Perimeter Institute Director and BMO Financial Group Isaac Newton Chair in Theoretical Physics
• Beatrice Bonga, postdoctoral researcher, Perimeter Institute
• Asimina Arvanitaki, Perimeter Institute Faculty member and Stavros Niarchos Foundation Aristarchus Chair in Theoretical Physics
• Brian McNamara, Department Chair of Physics and Astronomy, University of Waterloo

"Analyses of the image - published in a series of six papers in the Astrophysical Journal Letters - confirm that within the limits of the EHT’s present sensitivity the shape and behavior of M87’s black hole fits Einstein’s predictions."
