Denis Burgarella

Denis Burgarella studied in Marseille (Lycée Marcel Pagnol) from 1975 to 1978. From 1978 to 1982, he studied at Université Aix-Marseille II (now Aix-Marseille University) DEUG A (Mathematics and Physics), in Licence de Physique, Maîtrise de Physique and DEA in Computer Sciences. After that, he moved to Nice University where he got a PhD in astrophysics (actually done in LAM), Images of the Universe (Nov. 1987).

• 1984 – 1987: PhD in Laboratoire d'Astronomie Spatiale de Marseille (now Laboratoire d'Astrophysique de Marseille)
• 1987 – 1989: CNES Post-doc Laboratoire d'Astronomie Spatiale de Marseille (now Laboratoire d'Astrophysique de Marseille)
• 1989 – 1992: Post-doc PhD in Space Telescope Science Institute (STScI)
• 1992 – Now: Permanent position (Astronomer) in Laboratoire d'Astrophysique de Marseille

His 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)).[4] 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).[5] 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.
