Scientific career

After studying mathematics at the Saint-Charles University of Marseilles in 1976, Luminet moved to Paris-Meudon Observatory to undertake a Ph. D. with Brandon Carter as his advisor. He met Stephen Hawking at the Department of Applied Mathematics and Theoretical Physics in Cambridge, England. He defended his Ph.D. thesis in 1977 at Paris University on the subject of ''Singularities in Cosmology''. In 1979, Luminet got a permanent research position at the CNRS and developed his scientific activities at Paris Observatory until 2014, before joining the Laboratoire d'Astrophysique de Marseille. During the two year interval, he was a visiting scientist at the

, Chile (2005). In 1979, Luminet created the first "image" of a black hole with an accretion disk, using nothing but an early computer, math, and India ink. He predicted that it could apply to the supermassive black hole in the core of the elliptical galaxy M87. In April 2019, the

Consortium confirmed Luminet's predictions by providing the first telescopic image of the shadow of the M87* black hole and its accretion disk. In 1982, along with physicist Brandon Carter, Luminet invented the concept of a Tidal disruption event (TDE), the destruction of a star passing in the vicinity of a supermassive black hole. They showed that this phenomenon could result in the violent destruction of the star causing a "stellar pancake" and nuclear reactions in the core of the star in the stage of its maximum compression. With other collaborators, Luminet predicted specific observational signatures and introduced the concept of "tidal supernovae". The theory of TDE was confirmed by observing eruptions resulting from the accretion of stellar debris. It explains the superluminous supernova SN 2015L, the tidal explosion of a white dwarf before being absorbed beneath a massive black hole. In 1995, with his colleague , Luminet coined the term "Cosmic Topology" for describing the shape of space, proposing a variety of universe models compatible with the standard Friedmann-Lemaître models of relativistic cosmology. In 2003, large scale anomalies in the anisotropies of the
