9.09.2021:Amaldi Medal for prof. Andrzej Trautman

The Amaldi Medal of the Italian Society of General Relativity and Gravitational Physics for the year 2021 is awarded to Professor Andrzej Trautman for his fundamental contributions to the theory of gravitational waves. The prize, named after the famous physicist Edoardo Amaldi who was one of the fathers of experimental gravitational physics, is awarded every two years to European scientists who have made significant contributions to general relativity and gravitational physics.

24.03.2021: It was with great sadness that we learned that Ted Newman, an honorary member of our Society, passed away on March 24, 2021, at the age of 92.

Ted Newman was born in New York City and graduated from the famous Bronx High School of Science there, then studied physics at New York University where he received his B.S. in 1951. He did his doctoral studies at Syracuse University in Peter Bergmann's group receiving his PhD in 1956. In 1956 he joined the University of Pittsburgh and worked there for the rest of his life. In the early 1960s Peter Bergmann organized a large group at Syracuse to work on the general theory of relativity. Members of this group included Joshua Goldberg, Roger Penrose, Rainer Sachs, Roy Kerr and for the 1960/61 academic year Ted Newman was also there. The focus was on research on two fundamental problems - gravitational waves and quantization of the gravitational field. Roger Penrose was fascinated by the spin description of the gravitational field and, together with Newman, wrote down Einstein's equations in the language of spinors creating the Newman-Penrose formalism, which is still popular today. Over the next several years, Newman developed this formalism and applied it to the study of the asymptotic properties of the gravitational field and the search for new exact solutions to Einstein's equations. Using this formalism, he found a rigorous solution to the Einstein-Maxwell equations describing an electrically charged and rotating black hole. Such a black hole is now called a Kerr-Newman black hole. He and his collaborators L. Tamburino and T. Unti found a vacuum extension of the Schwarzschild metric now known as the NUT spacetime. The Newman-Penrose formalism naturally introduces a composite description of spacetime. Together with Allen Janis, Newman proposed a new method for finding exact solutions to Einstein's equations using the complex coordinate rotations and basis vectors used in the Newman-Penrose formalism. The study of the asymptotic properties of gravitational and electromagnetic fields led to the discovery of asymptotic null surfaces associated with the congruence of null geodesic without shear. The intersection of these surfaces with the null boundary of conformally completed spacetime was named Heaven because they are self-dual solutions to Einstein's vacuum equations. The study of null geodesic congruences also allowed Newman to introduce the classification of caustics and wave fronts and a more accurate description of gravitational lensing. More recently, Newman has been interested in the possibility of reproducing the behavior of compact sources of a gravitational field from the asymptotic properties of that field. Ted Newman first came to Poland in 1962 for the International Conference on the Theory of Gravitation in Jablonno. He took a special liking to Poland and came very often, usually together with Josh Goldberg. His favorite time for visits was the second half of June, when fresh strawberries and cherries were available at the stalls in Warsaw. Ted Newman was usually full of energy and ideas. He liked classical music and greatly appreciated Górecki and especially Penderecki. He was last in Warsaw for Jurek Fest in September 2019.

Sir Roger Penrose, Honorary Member of the Polish Society on Relativity is among the 2020 Nobel Laureates in Physics. His distinguished achievement is the black hole theory. The concept of a black hole can already be found in the work of Laplace and was developed thanks to Einstein's theory and the solutions of Schwarzschild and Kerr (to which also Robinson and Trautman contributed). However, it was Sir Roger who proved the spacetime singularity theorem and formulated the cosmic censorship conjecture that imply that black hole is the final stage for a large class of gravitational collapse processes, in fact inevitable if a trapped surface has formed in space-time. Penrose also discovered, in a purely theoretical way, the process of extracting energy from a black hole at the expense of its momentum. Today's observations confirm the role that the Penrose process plays in black hole astrophysics. PoToR members continue to research various new issues in black hole theory.

Sir Roger also made outstanding contributions to other areas of the theory of gravity and other fields of science. His works on the asymptotic properties of space-time are fundamental for the theory of gravitational radiation. Penrose's theory of twistors led to the development of new branches of differential geometry and algebraic topology. Penrose's tailing found its realization in nature in the form of quasicrystals, a special form of a solid state in which atoms arrange themselves in an apparently regular, but not repeating structure. Penrose's Triangle Impossible was the inspiration for Escher's paintings.

The last time we hosted Sir Roger Penrose in Poland as a guest of the conference on the occasion of Jerzy Lewandowski's 60th birthday on September 16-20, 2019. Sir Roger gave a lecture on the theory of twistors:

Roger: Congratulations!

Another part of the Nobel Prize in Physics 2020 is shared by prof. Andrea Ghez (University of California, Los Angeles) and prof. Reinhard Genzel (Max Plank Instiute for Extraterrestrial Physics, Garching) "for the discovery of a supermassive compact object at the centre of our galaxy". They are leaders of two research teams, who have been monitoring the motions of stars orbiting the Galactic centre for nearly three decades. Genzel’s group used telescopes in Chile operated by the European Southern Observatory (ESO), while Ghez and her colleagues used the Keck Observatory in Hawaii. Their works have been essential for proving that the supermassive black hole resides in the center of our Galaxy, as predicted by the theory of gravity. Penrose’s discovery of the singularity theorem showed that black holes are a robust consequence of general relativity, forming naturally in very overdense regions. The central few parsecs of the Milky Way harbours a rich cluster of stars and hot gas. These have been used to trace the gravitational potential of the Galactic centre defined by the compact radio source Sagittarius A* (Sgr A*), at a distance of 25,000 light years. If the mass concentration at the very centre of the Galaxy is made of a single supermassive black hole, the velocities of stars there should be growing for progressively smaller radii, as for planets around the Sun. Such Keplerian orbits should not arise if the mass is due to a spatially distributed cluster of stellar-mass objects. Thanks to the work of Ghez and Genzel's groups, the orbits of the brightest stars closest to the middle of the Milky Way have been mapped with increasing precision. Their pioneering work has given us the most convincing evidence yet of a supermassive black hole at the centre of the Milky Way.

Prof. Andrea Ghez became 4th woman winning Nobel Prize in Physics, after Maria Curie-Skłodowska (1903), Maria Goeppert-Mayer (1963), Donna Strickland (2018).
