Education
editDenis Burgarella studied in Marseille (Lycée Marcel Pagnol) from 1975 to 1978. From 1978 to 1982, he studied at Université Aix-Marseille II (now Université d'Aix-Marseille). After that, he moved to Nice University where he got a Ph.D. in astrophysics at LAM.[2] From 1987 to 1989, he did a CNES Post-doc there as well. From 1989 to 1992 he did a post-doc in Space Telescope Science Institute.
Career
editSince 1992 Burgarella has a permanent position as an astronomer in LAM.
He was president of SF2A from 2008 to 2010.[3] He was president of the J1 commission of the International Astronomical Union (IAU) from 2015 to 2018. From 2018 to 2021, he is president of IAU Division J. (Galaxies and Cosmology)[4]
Research
editHis research works are about galaxy at all redshifts (z), in a cosmological context and more specifically on the formation and evolution of galaxies and the detection, identification and study of galaxies in the early universe using a multi-wavelength approach (Spectral Energy Distribution, SED) via observation and modelling. In Burgarella et al. (2020)).[5] Denis Burgarella and his colleagues have identified and characterised (some of) the first dust grains created from stars in the universe at redshifts 5 < z < 10.
To understand these galaxies, they have developed, with Médéric Boquien and a team to seven people, a code that models the emission of galaxies from the X-rays to the sub-mm: CIGALE, Code Investigating GALaxy Emission).[6] CIGALE is parallelised in Python 3 and is designed to fit large samples of several ten of thousands observed SEDs by comparing the observed data to several 100 million models.
