Description

A conference in celebration of Brandon Carter's 80th birthday

Brandon Carter is one of the leading figures in general relativity and more specifically in black hole physics. He performed major advances in establishing the famous 'no hair' theorem and the laws of black hole thermodynamics. Various physical concepts are named after him, among which the Carter constant, the Carter tetrad, the Carter time machine and the Carter-Penrose diagrams. Brandon Carter has also developed the theory of superfluidity in relativity, as well as the geometry of cosmic strings and more generally of membranes in spacetime. He is also known in the field of epistemology for having formulated the weak anthropic principle, and in the context of the superstring "landscape" for having formulated the strong anthropic principle.

 

The conference will focus on the theory of black holes, topological defects in cosmology, the physics of neutron star interiors and the anthropic principle. The aim is to present the latest developments in the above-mentioned areas and to discuss the prospects for future research.

The conference is organized by Éric Gourgoulhon (LUTH, Observatoire de Paris) and Patrick Peter (IAP, Paris) and will take place

      Carter’s inspirations : from BKL conjecture to Stellar Pancakes 30m IAP, Paris

      IAP, Paris

      As a beginning researcher I had the chance to benefit from Brandon's wise advice for my early work, from my 1977 thesis on cosmological singularities that he directed to his suggestion to numerically visualize black holes in 1978. Then we could fully collaborate from 1982 to 1986 in a series of pioneering papers on the modelisation of tidal disruption of stars by big black holes.

      A visual journey into some Carter-Penrose diagrams 30m IAP, Paris

      IAP, Paris

      Although it looks simple, the Schwarzschild metric describes a complicated spacetime that is endowed with two asymptotic regions and two singularities. The situation is even more complicated for charged or spinning black holes. Grasping the complexity of these metrics can fortunately be achieved thanks to the celebrated Carter-Penrose diagrams. However, such diagrams do not allow to guess the complexity of the actual visual aspect of these metrics, that is, how a set of celestial spheres are distorted in the presence of strong gravitational fields. Conversely, addressing this issue necessitates to propagate geodesics in metrics that, most of the time, cannot be covered by a unique coordinate system and for which locating photons and oneself in a causal diagram is mandatory. In this talk, I will show a few movies of what an observer would see when travelling within a few black hole metric maximal analytic extensions: Schwarzschild, Reissner-Nordström and, of course, Kerr.
