Description
One of the foundations of the concordance cosmological model is that approximately 85 per cent of the matter content of the Universe is in the form of some yet unknown component that we can detect only through its gravitational effect: dark matter. While the standard Cold Dark Matter model is very successful at explaining the large scale structure distribution of the universe, it has been challenged by observations at the scale of galaxies and below, motivating the exploration of alternative scenarios such as Self-Interacting or Warm Dark Matter.
I will present the first results from the new AIDA-TNG project, where we simulate three cosmological volumes, including six dark matter scenarios together with galaxy formation. Resolving systems from 10^9 to 10^14.5 solar masses, the AIDA-TNG project offers crucial new data to understand the effect of alternative dark matter models on multiple scales and observables. I will present our results on the density profiles of dark matter halos and subhalos, stellar and halo shapes, as well as the effect of SIDM and WDM on the properties of the galaxy general population. Moreover, I will talk about our first insight on large-scale power spectra and the Lyman-alpha emission on large scales, demonstrating the promising potential of this sample.
