DIMITRIS PSALTIS, the Greek, Who Took the First Picture of a Black Hole, Apr 11, 2019

A Greek researcher of the Diaspora Dimitris Psaltis, professor of astronomy and physics at Arizona University, played a key role in the new Event Horizon Telescope (EHT) that took the first picture of a black hole [19659002] The monstrous black hole in Messier The 87 galaxy has a diameter of about 40 billion kilometers (three million times greater than the Earth) and is located at a distance of 500 million trillion kilometers
D. Psaltis and his colleagues first undertake once in such an astrophysical scale – to investigate whether the black hole image verifies Albert Einstein's general theory of relativity. For this purpose, the relevant "tests" developed and concluded that Einstein was once again justified, as the black hole image finally fits well into the simulations preceding it on the basis of the theory

Immediately After today's announcement, the Greek astrophysicist said: "The EHT telescope for the first time allowed us to test Einstein's general theory of relativity about super-big black holes in galaxy centers. The size and shadow of the black hole in the M87 galaxy photographed confirms the exact predictions of Einstein's general theory of relativity, which increases our confidence The exhibition of a black hole is just the beginning of our quest to develop new tools that allow us to interpret the extremely complicated facts of nature. "



Dimitris Psaltis was born in Serres 1970 and took He received his PhD from Aristotle University in Thessaloniki in 1992. He completed his PhD at the University of Illinois (1997) and was a postdoctoral researcher at the Harvard-Smithsonian Center for Astrophysics, MIT University and the University of Preventive Studies Institute, and has been awarded by the Bodossakis Foundation (2005). 

Since 2003, he has taught at the University of Arizona, where he is currently a professor of astronomy and physics. His research focuses on the control of Einstein's general theory of relativity on a cosmic scale, which primarily studies black holes and neutron stars.

Mr. Psaltis treats the telescope of Horizons of Events from his early stages. With his research team at the University of Arizona, he developed the General Relativity Theory test, which the EHT telescope performs. He has also developed simulation algorithms on computers that predict how the first images of black holes will look.

In addition to EHT, he is a member of Scientific Panels of ESO and NICER's LOFT mission NASA, and the Scientific Advisory Board of the Max Planck Institute in Bonn
