Astrophysics colloquium: What can we learn about Dark matter nature and baryonic physics?

Dr. Santi Roca-Fàbrega, Division of astrophysics, Department of Physics, Lund University

From AGORA to the Arrakihs ESA F2 space mission: What can we learn about Dark matter nature and baryonic physics?

In this talk, I will present the most recent results within the AGORA collaboration on the study of satellite galaxies and tidal streams and will put them in the context of the future ESA-F2 space mission known as ARRAKIHS.

In the first part of the talk, I will present both collaborations (AGORA and the ARRAKIHS consortium) to quickly move on how the results from high resolution simulations can help the community to better constrain the baryonic physics or even the nature of dark matter that needs to be implemented in the theoretical models to reproduce the high quality observations provided by present and future large observational efforts.
