French astrophysicist

Jean Pierre Luminet (born 3 June 1951) is a French astrophysicist, specializing in black holes and cosmology. He is an emeritus research director at the CNRS (Centre national de la recherche scientifique). Luminet is a member of the Laboratoire d'Astrophysique de Marseille (LAM) and Laboratoire Univers et Théories (LUTH) of the Paris Meudon Observatory, and is a visiting scientist at the Centre de Physique Théorique (CPT) in Marseilles. He is also a writer and poet. Luminet has been awarded several prizes on account of his work in pure science and science communication, including the Georges Lemaître Prize (1999) in recognition of his work in cosmology. In November 2021, he received the UNESCO Kalinga Prize for the Popularization of Science. He serves on the editorial board of Inference: The International Review of Science. The asteroid 5523 Luminet, discovered in 1991 at Palomar Observatory, was named after him. Luminet has published fifteen science books, seven historical novels, and six poetry collections. He is an artist, an engraver, a sculptor, and a musician. During his music career, he has collaborated with composers such as Gérard Grisey and Hèctor Parra. Some of Luminet's literary works have been translated into other languages, such as Chinese, Korean, Bengali, German, Lithuanian, Greek, Italian or Spanish.

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 University of São Paulo, Brazil (1984 and 1988), at the University of Berkeley, California (1989–1990) and a visiting astronomer at the European Southern Observatory, 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 Event Horizon Telescope 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 fr, 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 cosmic microwave background observed by the Wilkinson Microwave Anisotropy Probe led to Luminet suggesting that the shape of the universe is a finite dodecahedron, attached to itself by paired opposite faces, forming a Poincaré homology sphere. During the following years, astronomers searched for more evidence to support this hypothesis but found none. Jean Pierre Luminet is a specialist in the history of cosmology and in particular the emergence of the concept of the Big Bang. He emphasizes in several books and articles the leading role played by the Belgian priest and cosmologist Georges Lemaître. In 2018, the International Astronomical Union (IAU) recommended that Hubble's law be known as the Hubble Lemaître law. Luminet published a critical analysis of the Holographic principle and the AdS/CFT correspondence while working on Quantum gravity.

Luminet is devoted to drawing, engraving (learned with Jean Delpech at Ecole Polytechnique), and sculpture. A thorough analysis of his artwork has been done by Martin Kemp, Professor of Art History at Oxford University. In the field of music, Luminet collaborated in 1991 with Gérard Grisey (a former pupil of Olivier Messiaen and Henri Dutilleux) to produce a piece of cosmic music called Le Noir de l'étoile Composed of an ensemble of 16 soloists, large orchestra, and electronics, the piece describes an Utopian voyage through a giant black hole. It was created in 2018 in Barcelona, Paris, and Köln. In 1998, Luminet was a curator of the exhibition Figures du Ciel (Figures of Heaven), coupled to the opening of the new Bibliothèque nationale de France. (October 1998 – January 1999)
