  • Astro-PAHs infrared emission, from the laboratory to the interstellar medium

01/05/14

Un financement de thèse est disponible dans le groupe Astrophysique et Edifices Moléculaires au laboratoire ISMO de l’Université Paris Sud.

Project description:
Dust is a key component of the interstellar medium and plays a capital role in many astrophysical processes. During this PhD, we will tackle the aromatic carbon bearing component responsible for the emission bands observed in the mid-infrared, the so-called Aromatic Infrared Bands (AIBs), thanks to dedicated laboratory experiments and numerical simulations. The size range of the laboratory analogues will span several Angstrom to few nanometers, that is to say containing tens to a few hundreds of carbon atoms, a range which remains scarcely explored although of great astrophysical relevance.
Methods:
To study these “astro-PAHs”, the spectrometer Firefly will be coupled to the Nanograins experimental set-up wherein a flame is used to produce analogues of the interstellar carbonaceous dust. Firefly is dedicated to the measurement of IR emission of molecules and nanoparticles in the gas phase following excitation by light. A numerical simulation effort will also be undertaken using some theoretical tools developed in the recent years in our group. The IR emission spectra of nanoparticles resembling those produced in Nanograins will be computed. Comparison between experimental, theoretical and astrophysical spectra will thus be conducted.
Profile description:
We are looking for a candidate having a master in the field of physics or physical chemistry, with good experimental and programming skills.
Application:
Please send a complete CV, 2 letters of recommendation as well as a list of the courses followed in 2013-2014 with grades and possibly ranking to Prof. Pascal Parneix and/or Dr. Thomas Pino . The deadline for application is end of July 2014 but the position will be filled asap.
