Unveiling the nature of dark matter with space telescopes
The famous "Bullet Cluster" where we have observed two massive galaxy clusters that have collided. During the collision the hot gas (depicted in red) that exists in the cluster has interacted with each other and separated from their member galaxies. The dark matter as mapped by gravitational lensing traces the dark matter in the cluster (https://iopscience.iop.org/article/10.1086/508162)
Gravitational lensing of massive galaxy clusters
Space telescopes have enabled high precision gravitational lensing allowing us to map out the distribution of dark matter in these environments.
Dark Matter and Deep learning
Deep learning presents a new and exciting way to unveil the nature of dark matter. Using novel algorithms we can extract the subtle signatures of dark matter from the data in order to better understand our Universe.
Weak Gravitational lensing of Cosmos-Web
The James Webb Space Telescope is revolutionising astrophysics with its deep, high resolution observations. The largest programme was the COSMOS-WEB program, observing 1 square degree around the COSMOS field. We are leading the weak gravitational measurement of this field that will ultimately provide the deepest and highest resolution map of the cosmos ever created.
Hydrodynamical simulations of massive galaxy clusters with exotic dark matter
Hydrodynamical simulations of massive galaxy clusters are vital if we are to understand and interpret the observations we make. At EPFL we are leading the development and running of exotic dark matter models that will enable the discoveries of the future.
Self-interacting dark matter with European Space Telescope, Euclid
The all-sky space telescope Euclid will change the face of cosmology. Observing over 14,000 square degrees, down to unprecedented depths it will deliver a view of the Universe that we have never seen. In particular it will deliver observations of thousands of galaxy clusters that will shed light on the nature of dark matter. We at EPFL are leading many projects to understand dark matter with the Euclid telescope.
Unveiling the nature of dark matter with the Hubble Space Telescope
The Hubble Space Telescope has been the origin of many astronomical discoveries and to this day has a rich archive of many observations of galaxy clusters. We are using this rich dataset to discover more about our Universe and further understand what is dark matter.
