Anthony Jones has been trying to understand the chemical composition, structure, origin and evolution of cosmic dust in the Milky Way and galaxies beyond for more than 30 years. It has therefore taken him a long time to come to the conclusion that a dust model firmly anchored to laboratory data is the only conceivable way to go. His dust modelling efforts are therefore the fruits born of the roots planted by the early cosmic dust modelling pioneers. Researcher, CNRS, IAS, Orsay, France |
![]() | Nathalie Ysard's role in THEMIS concerns dust emission/extinction modelling (with or without radiative tranfer) and dust optical property calculations. Her scientific interests, among others, concern dust evolution in the ISM, in particular to understand the first stages of star formation. Researcher, CNRS, IAS, Orsay, France |
![]() | Melanie Koehler's role in THEMIS is to calculate the optical properties of the dust particles, to derive the material composition of the grains, and to investigate the evolution of dust towards the denser regions of the ISM. Former research Fellow, Queen Mary Universty, London, United Kingdom Now a data scientist |
Marco Bocchio has been involved in the THEMIS framework studying the grain charging effect as well as Coulomb fragmentation in HII regions. Using the THEMIS dust model, he also explored the dust destruction efficiency in supernova-triggered shock waves. Former research fellow, Osservatorio di Arcetri, Arcetri, Italy Now a data scientist |
![]() | Laurent Verstraete's role in THEMIS is to make the interface with the DustEM numerical tool. He also contributes to the calculation of the grain optical properties and to the study of the grain photo-processing (charge, Coulomb explosion, photoelectric effect).
