The AIDA-TNG project

We introduce the AIDA-TNG project - "alternative dark matter in the TNG universe", a suite of cosmological magnetohydrodynamic simulations that simultaneously model galaxy formation and different variations of the underlying dark matter model. We consider the standard cold dark matter model and five variations, including three warm dark matter scenarios and two self-interacting models with constant or velocity-dependent cross-section. In each model, we simulate two cosmological boxes of 51.7 and 110.7 Mpc on a side, corresponding to TNG50 and TNG100, and combine the variations in the physics of dark matter with the fiducial IllustrisTNG galaxy formation model. We can thus select a large variety of objects from the cosmic web and compare not only their dark matter haloes in multiple models (rainbow colors in the figure), but also the baryonic distribution (blue color scale representing gas density).The AIDA-TNG runs are thus ideal for studying the simultaneous effect of baryons and alternative dark matter models on observable properties of galaxies and large-scale structures.
