The Universe on a mobile phone
(Press coverage of Leclercq et al. 2020)05-2020 Comparison between a traditional simulation (left panel) and a simulation using our new algorithm (right panel). In our approach, the volume of the simulation is a mosaic made of "tiles" calculated independently and whose edges are represented by dotted lines.

"Entropy" in French12-2017
I have been recently involved in Entropy, a collaboration project of artists and scientists which aims to frame a public lecture staged as an immersive live audiovisual performance. I have been in charge of translating the script, which tells the cosmic story of creation, into French. Stay tuned for future performances of the show in French!
Novel maps of matter flows in our cosmic neighbourhood
(Press coverage of Leclercq et al. 2017)07-2017 Slice through the celestial equator showing the radial component of the velocity field (in kilometers per second). Blue regions are falling towards us and red regions are flying away from us. Galaxies of the Sloan Digital Sky Survey main galaxy sample are overplotted. In the centre of the slice, the infalling dynamics of the Sloan Great Wall, one of the largest structure of the known Universe, can be observed. Figure from Leclercq et al. 2017.

Stars containing dark matter should look different from other stars
(Press coverage of Iocco et al. 2012)02-2012 A Hertzsprung-Russell diagram for stars of one solar mass in environments with varying asymmetric dark matter densities. At lower densities (blue and purple lines), the stars are brighter, while at higher densities (green and orange lines), the stars are cooler when compared to stars on the standard path that contain no dark matter. Figure from Iocco et al. 2012.
