🌌 One step closer to unveiling dark matter

What is the dark matter? Is it hot or cold? Is it self-interacting? Can you eat it? 🤔

EPFL is leading the ARRAKIHS consortium, which will launch a satellite selected by ESA to address the nature of dark matter. The signature of the nature of dark matter is imprinted in the number of faint dwarf systems around massive galaxies, such as our own, and stellar streams in their halos. With the help of very efficient imaging technology, the scientists will unveil and characterize the stellar halo features an engineering challenge given the faintness of the astrophysical structures

The name ARRAKIHS (acronym for Analysis of Resolved Remnants of Accreted galaxies as a Key Instrument for Halo Surveys) alludes to the sci-fi planet in the novel Dune, but instead of looking for “spice”, this low-earth orbit satellite will be looking to unveil one of modern physics darkest secrets.

La matière oire est une composante mystérieuse de l'univers. Est-elle chaude, froide? Peut-on la manger? 🤔

L'EPFL dirige le consortium ARRAKIHS, qui lancera un satellite sélectionné par l'ESA pour étudier la nature de la matière noire. Le satellite utilisera une technologie d'imagerie efficace pour révéler les caractéristiques du halo stellaire autour des galaxies massives, permettant ainsi de percer l'un des plus grands secrets de la physique moderne.
