Postdoctoral Researcher (M/F)

id="offer-description" class="ecl-u-type-heading-2 ecl-u-mt-none ecl-u-mb-l">Offer Description The successful candidate will carry out postdoctoral research within the LPENS astrophysics team, as part of the ANR ForeSight project, which develops innovative approaches to separating the primordial B-modes of the cosmic microwave background from polarized Galactic microwave foregrounds. The precise research topic will be defined jointly with the team at the start of the contract, depending on the candidate's skills and interests and the progress of the project.Two main axes structure the project and will serve as a starting point for defining the topic: (i) extending ST-based component separation to multi-frequency, multi-component configurations, in connection with the application to detecting primordial CMB B-modes; (ii) positioning these methods relative to classical component-separation approaches, both through validation and hybridization with these approaches, and through the development of new ST algorithms built from scratch where existing methods fall short. Contribute to the development of non-Gaussian component-separation algorithms based on Scattering Transforms, in particular in multi-frequency configurations (extending the framework developed in Tsouros et al. 2026). Study how ST methods relate to classical component-separation approaches (GNILC, SMICA, NILC, Commander, parametric approaches): comparison, cross-validation, and hybridization where relevant.
