In 2022, the European Space Agency will launch the Euclid satellite dedicated to the study of dark energy and dark matter. Euclid will observe a large fraction of the sky in the visible and near-IR, and will use galaxies as probes of the 3D structure of the Universe as a function of cosmic time. The area of the sky that will be surveyed by Euclid contains the darkest sky regions , chosen to avoid contamination by interstellar dust as much as possible, but dust is present on every line-of-sight, at various level.
This thesis will use state-of-the art observations of interstellar dust in the visible/near-IR range recently obtained with Megacam on the Canada-France-Hawai Telescope. These images, taken as a part of a large program to complement the Euclid data, reveal the structure of the interstellar medium with very fine details, giving us a taste of what Euclid will observe over vast areas. The aim is to analyse these images both in an interstellar context (dust and structure) and in the context of Euclid, to characterise this contaminating emission and contribute to the optimal scientific return of the mission.
The PhD will be done at Université Paris-Saclay, under the direction of N. Ysard (IAS) and M.-A. Miville-Deschênes (AIM). A master’s degree in astrophysics or equivalent is a prerequisite for application.
