If you are currently employed in academia and would like to work within the Aquila consortium, please get in touch with us through this form or reach out to individual members to discuss potential collaborations.
We have opportunities for people interested in joining our institutions, at different levels of seniority:
- Bachelor and Master projects, for internships at the Bachelor or Master level,
- PhD projects, for longer projects leading to a PhD in cosmology and/or data science,
- Postdoctoral positions and Fellowships, if you hold a PhD degree in a relevant field (including astronomy, statistics, or computer science),
- Faculty positions, if you are looking for a permanent academic position in one of our institutions.
Bachelor and Master projects
We continually have opportunities for Bachelor and Master projects in our different institutions, which we typically discuss directly with candidates. Please choose the person you would like to work with and make direct contact by email.

October 2025: Internship: Tessellations in cosmological N-body simulations
Tessellation techniques are widely used in observational and computational cosmology to adaptively sample sets of data points while controlling signal-to-noise ratio. They are useful to analyze the morphology of the observed large-scale galaxy distribution (e.g., the Euclid survey, which represents the main collaborative framework of this project, but also DESI, LSST, etc.), or simply for obtaining accurate estimates of the local density and velocity field in the dark matter distribution generated from a N-body simulation, for subsequent post-processing to create simulated observations, such as synthetic Lyman-alpha forests (e.g., DESI), virtual galaxy catalogs (notably Euclid, but also DESI, LSST), or mock gamma-ray sky surveys for indirect detection of dark matter (e.g., Fermi LAT). However, tessellation methods are still not free of noise and usually require additional processing to obtain a smoother representation of the data. In particular, an important challenge is to be able to accurately measure the velocity field and its spatial derivatives in a cosmological N-body simulation. Here we propose to do so by applying a local adaptive convolution to the tessellation network, which can be performed directly with the appropriate percolation algorithm, and to test the ability of such an algorithm to generate smooth velocity fields and their derivatives, with comparisons to methods already existing in the literature.
