HPC supports first black hole image


Scientists have obtained the first image of a black hole, using Event Horizon Telescope observations of the centre of the galaxy M87. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun. This long-sought image provides the strongest evidence to date for the existence of supermassive black holes and opens a new window onto the study of black holes, their event horizons, and gravity.

16 Apr 2019 Brussels - On 10 April 2019 the first-ever image of a black hole was unveiled. This once-in-a-lifetime achievement would not have happened without the support of a global team of dedicated scientists, and of European supercomputers. During a live-streamed press conference in Brussels, spectators were treated to a short video zooming in on galaxy M87 to end with a view of the supermassive black hole that exists at its centre and is 6.5 billion times more massive than the Sun.

BlackHoleCam scientists as part of the Event Horizon Telescope (EHT) Consortium contributed to obtain the long-sought image, which actually shows the "shadow" of the black hole surrounded by a bright ring. The black hole itself remains hidden, as light bends in the intense gravity and cannot escape to show us what reality looks like beyond the event horizon (point of no return).

Prof. Dr. Luciano Rezzolla, Chair of Theoretical Astrophysics at the Goethe University, Frankfurt, Germany, and one of the principal investigators (PI) of BlackHoleCam is part of the global network of more than 200 scientists that needed one year and eight telescopes to achieve their feat.

In addition to the telescopes, the team used supercomputing resources to explore theoretically the various aspects of this discovery and understand the properties of the black hole. The German Tier-0 systems SuperMUC, hosted by LRZ in Garching, HazelHen, hosted by HLRS in Stuttgart, and the LOEWE cluster in CSC in Frankfurt, were directly employed in these calculations. SuperMUC and HazelHen are part of the PRACE Research Infrastructure (RI) that supports excellent science and engineering in Europe.

"Two aspects of our work that would have been impossible without supercomputers: the direct simulations that first produce the plasma dynamics near a black hole and subsequently the appearance of the 'shadow' from a black hole, and the data reduction needed to turn the huge amount of interferometric data from the radiotelescopes into an image", explained Prof. Dr. Rezzolla.

When using world-class HPC systems, the need for efficient algorithms and skilled scientific programmers increases significantly. Katie Bouman, who is an assistant professor at the California Institute of Technology's computing and mathematical sciences department, was one of the talented scientists on the EHT team. The image showing her excitement at the first viewing of the image has gone viral, and has given a young and female face to universe science.

"In international projects with diverse teams of highly skilled and motivated people, the best scientific results are achieved. This project, which combines the most advanced technology with the finest theoretical supercomputer simulations, is a good example of that", Prof. Dr. Rezzolla added.

Prof. Dr. Luciano Rezzolla is a Member of the PRACE Access Committee, the body that gives advice to the Board of Directors concerning the allocation of resources of the RI.

The image opens new windows onto the study of black holes, their event horizons, and gravity, and PRACE will continue to support excellent research in this field via its Call for Proposals for Project Access. To date PRACE has supported 17 such projects, providing them with more than 780 million core hours combined. The topic is also featured in the Scientific Case for Computing in Europe 2018-2026 , which the PRACE Scientific Steering Committee, the body that provides advice and guidance on all matters of a scientific and technical nature which may influence the scientific work carried out by the use of the resources provided by PRACE.
