Jean-Pierre Luminet (born 3 June 1951) is a Frenchastrophysicist, specializing inblack holes andcosmology. He is anemeritus research director at the CNRS (Centre national de la recherche scientifique). Luminet is a member of theLaboratoire d'Astrophysique de Marseille (LAM) and Laboratoire Univers et Théories (LUTH) of theParis-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 inpure science andscience communication, including theGeorges Lemaître Prize (1999) in recognition of his work in cosmology. In November 2021, he received the UNESCOKalinga Prize for the Popularization of Science. He serves on the editorial board ofInference: The International Review of Science.[1]
The asteroid5523 Luminet, discovered in 1991 atPalomar Observatory, was named after him.[2][3]
Luminet has published fifteen science books,[4] seven historical novels,[4] TV documentaries,[5] and six poetry collections. He is anartist, anengraver, asculptor, and amusician.[6] During his music career, he has collaborated with composers such asGérard Grisey[7] andHèctor Parra.[8] Some of Luminet's literary works have been translated into other languages, such as Chinese, Korean, Bengali, German, Lithuanian, Greek, Italian or Spanish.[9]
After studying mathematics at the Saint-Charles University of Marseilles in 1976, Luminet moved to Paris-Meudon Observatory to undertake a Ph. D. withBrandon Carter as his advisor. He metStephen Hawking at theDepartment of Applied Mathematics and Theoretical Physics in Cambridge, England. He defended his Ph.D. thesis in 1977 at Paris University on the subject ofSingularities 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 theUniversity of São Paulo, Brazil (1984 and 1988), at theUniversity of Berkeley, California (1989–1990) and a visiting astronomer at theEuropean Southern Observatory, Chile (2005).
In 1978, Luminet created the first "image" of a black hole with an accretion disk, using nothing but an early computer, math, andIndia ink. He predicted that it could apply to the supermassive black hole in the core of the elliptical galaxy M87.[10] In April 2019, theEvent 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 physicistBrandon Carter, Luminet invented the concept of aTidal disruption event (TDE), the destruction of a star passing in the vicinity of a supermassive black hole.[11] 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 supernovaSN 2015L, the tidal explosion of a white dwarf before being absorbed beneath a massive black hole.
In 1995, with his colleagueMarc Lachièze-Rey [fr], Luminet coined the term "Cosmic Topology"[12] for describing the shape of space, proposing a variety of universe models compatible with the standardFriedmann-Lemaître models of relativistic cosmology.
In 2003, large scale anomalies in the anisotropies of thecosmic microwave background observed by theWilkinson Microwave Anisotropy Probe led to Luminet suggesting that theshape of the universe is a finitedodecahedron, attached to itself by paired opposite faces, forming aPoincaré homology sphere.[13] 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 theBig Bang. He emphasizes in several books and articles[14] the leading role played by the Belgian priest and cosmologistGeorges Lemaître. In 2018, theInternational Astronomical Union (IAU) recommended thatHubble's law be known as the Hubble-Lemaître law.
Luminet published a critical analysis of theHolographic principle and theAdS/CFT correspondence while working onQuantum 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.[15][16]
In the field of music, Luminet collaborated in 1991 withGérard Grisey (a former pupil ofOlivier Messiaen andHenri Dutilleux) to produce a piece of cosmic music calledLe Noir de l'étoile[7] (The Black of the Star). This work for six percussionists, based on magnetic tape and astronomical signals coming frompulsars,[citation needed] is regularly performed around the world. In 2011, he began a collaboration withHèctor Parra, who composed the orchestral pieceCaressant l'horizon (Caressing the Horizon) inspired by Luminet's books. In 2017, Luminet wrote the scenario for Parra'sInscape.[17] Composed of an ensemble of 16 soloists, large orchestra, and electronics, the piece describes an Utopian voyage through a giantblack hole. It was created in 2018 in Barcelona, Paris, and Köln.
In 1998, Luminet was a curator of the exhibitionFigures du Ciel (Figures of Heaven),[18] coupled to the opening of the newBibliothèque nationale de France. (October 1998 – January 1999)
Luminet has received more than twenty prizes and honors, including:
