Dear Colleagues and Students,
You are cordially invited to Faculty of Science Seminar series. Our speaker is Professor Metin Gürses who is the faculty member of Department of Mathematics.
The title of Professor Gürses’s seminar is “History of Black Holes”
Date: Tuesday, 30 April 2019
Time: 15:40
Place: SA-240 Seminar Room
Faculty of Science
Abstract: Scientists pictured a black hole for the ¬rst time in great detail. This was achieved through a global network of radio dishes called “The Event Horizon Telescope” and produced the the ¬rst-ever¬ direct image of a black hole. The existence of black holes was ¬rst proposed by physicists nearly a century ago following Albert Einstein’s general theory of relativity, but the evidence was indirect. The Event Horizon Telescope now con¬rmed theoretical predictions and once more demonstrated that “a picture is worth a thousand words”. There are more than one black holes in the universe and the attention of astrophysicist was concentrated on M87 and Sagittarius A* since 2017. The ¬rst clean picture came from M87 and it took two years to put together the data. It is now possible to observe that M87 is spinning clockwise in the sky. Scientists are now studying to understand how the black hole produces it gigantic jets.
Professor Gürses will discuss the science behind the observations and what lies ahead. Please watch
the 2014 movie “Interstellar” and also see the information at
