The Center for Astrophysics and Gravitation (CENTRA) of the Instituto Superior Técnico (IST) is linked in various ways to the 2020 Nobel Prize in Physics. Thus, the text on the scientific basis of the award prepared by the Nobel Committee for Physics and published by the Royal Swedish Science Academy, entitled “Theoretical Foundations of Black Holes and the Supermassive Compact Object at the Center of the Galaxy”, cites several scientific articles, including an article by José Sande Lemos, IST Senior Lecturer and President of CENTRA, and Carlos Heredero, coordinating researcher of the Department of Mathematics of the University of Aveiro who has already worked in this center (you can see the appointment HERE).
The article was published in the “Gazeta de Física” in 2018 with the title “Black hole 50 years later: the genesis of its name”, “precisely to mark the 50th anniversary of the creation of the black hole concept, in 1968, by the North American theoretical physicist John Wheeler, from Princeton University (USA), who was one of the last collaborators of Albert Einstein ”, says José Sande Let’s read Expresso. we were surprised by the citation of our article ”, confesses the president of CENTRA, adding that“ it is extraordinary that Roger Penrose won the Swedish Oscar, he is an idol, one of the greatest men of the 20th century and he is more than a theoretical physicist, He is a mathematical physicist, he has such deep thought at all levels that he is above the Nobel Prize ”.
At the same time, CENTRA participates, with the researchers Paulo García, António Amorim and Vítor Cardoso, in an international cooperation project of the European Southern Observatory (ESO), an organization to which Portugal belongs and which has a wide network of telescopes in the Atacama Desert. , in Chile. The project is called Gravity Collaboration, it is coordinated by the German scientist Reinhard Genzel, one of the winners of the 2020 Nobel Prize in Physics, and develops a second-generation instrument for the interferometer of the VLT (Very Large Telescope) super-telescope. Interferometry is an optical technique used in astronomy that consists of combining the light from different telescopes, receivers or radio antennas, in order to obtain higher resolution images.
José Sande Lemos also says, referring to the text on the scientific basis of the 2020 Nobel Prize in Physics: “He also mentions two articles by my doctoral advisor at the University of Cambridge, Donald Lynden-Bell, for being the first scientist to propose that at the center of all galaxies there is a black hole, particularly in the center of the Milky Way ”.
