Jean-Loup Puget and his collaborators reported the first identification of the Cosmic infrared background using COBE data.
[1] He is also, along with Alain Léger, credited with the origin of the hypothesis that the series of infrared lines observed in numerous astrophysical objects are caused by emission from polycyclic aromatic hydrocarbons.
[2] He is currently principal investigator of the HFI module of the Planck space mission.
He has been a member of the Académie des sciences (France) since 2002 and was awarded the Prix Jean Ricard in 1989.
Jean-Loup Puget, Nazzareno Mandolesi and ESA Planck team were awarded 2018 Gruber Prize in Cosmology for their definitive measurements of the properties of our expanding universe.
