Dark matter modeling

We are using the rotation curves of distant galaxies to constrain the nature of dark matter using 3D forward modeling wit GalPaK3D. Project funded by the ANR DARK. Read more here.

Automatic redshift estimation

We are developping new methods for the automatic redshift estimation of large hyperspectral data cubes from instruments such as MUSE and BlueMUSE (and future facility WST). Read more here.

Characterizing the circum-galactic medium of star forming galaxies.

Which are the physical properties of the circum-galactic medium around star-forming galaxies? How do they evolve with redshifts? Are they related to the DM profiles ?
Learn how I am using state-of-the-art VLT/MUSE and VLT/UVES data to answer these questions.

The origin of the scaling relations

The origin of the scaling relations can be nicely explained by the bathtub model. Read more to find out how I am using spectropolarimetry data to study the Lyman-$\alpha$ polarization and discriminate between the different scenarios.
