Description
Understanding the effect of baryon-driven astrophysics on probes of large-scale structure is crucial to correctly interpret the increasingly precise data from ongoing surveys. The state-of-the-art cosmological hydrodynamic simulation, MillenniumTNG, represents a formidable tool in this respect. Combining a cosmologically representative volume of (740 cMpc)^3 and a mass resolution of ~3X10^7 Msun per baryonic mass element, MillenniumTNG enables us to resolve the detailed properties of galaxies over a very wide range of masses. I am therefore using this simulation and its dark-matter-only counterpart to study the impact of baryons on the concentration-mass relationship of haloes in an unprecedented halo mass range (~10^11-10^15 Msun) and redshift interval (0<z<7). I will show my preliminary results and discuss possible implications for cosmological probes such as lensing.
