Description
Understanding how modifications to the dark energy model affect the formation and evolution of galaxy clusters is of crucial importance to avoid potential biases when interpreting current and upcoming cosmological observations. However, this question remains relatively unexplored, particularly when realistic AGN feedback models are taken into account. In this presentation, I introduce the ADELINE suite of simulations, the first set of zoom-in simulations of galaxy clusters performed in alternative dark energy models and incorporating realistic baryonic physics, including AGN feedback.
These simulations provide a unique framework to investigate the sensitivity of the internal properties of galaxy clusters to the underlying dark energy model within the wCDM framework. I will discuss how modifications to the dark energy model impact the thermodynamic and structural properties of galaxy clusters throughout their redshift evolution, and investigate whether these signatures can be degenerate with the effects of AGN feedback.
Finally, I will examine the observational implications of these signatures, focusing on galaxy-cluster observables associated with the Sunyaev–Zeldovich and X-ray signals. These results provide a first step toward assessing the potential of the internal matter distribution of galaxy clusters as a probe of dark energy beyond LambdaCDM, while highlighting the importance of accurately modelling baryonic processes.
